Smiliarities and Differences Between Sharks vs Whales

Sharks Say They Are Out for Blubber!!!

Whales Want to Kick Some Prehistoric Tail!!!

Well to begin with Sharks are fish, and whales are mammals. Sharks lay eggs, Whale give live birth. Sharks are carniverous/omniverous and whales for the most part are not carniverous (but mainly derive protiens from plankoton). Sharks do not sleep, whales have a kind of sleep pattern as they are mammals. Which one is older evolutionarily is debatable - Sharks are older if you look at it from science, Whales are older if you look at it biblically. Sharks attack their food and hunt, Whales do not. Sharks do not raise their young, Whales stay with their young nearly six months. Sharks are not an endangered species, Whales are. Sharks are not trained to be entertainment at Seaworld or wildlife parks, Whales are. Sharks breed consistently in captivity, Whales do no breed as openly in captivity. Sharks have one natural enemy dolphins, Whales have one natural enemy the Giant Squid - and one unnatural enemy Man. Sharks have one of the smallest brains of any creature human size or larger, Whales have the a brain just barely bigger than a shark. Sharks appear to base almost all of their activity upon instincts and primal drives involuntarily, Whales appear to have some self determination as they occasionally committ suicide when old or injured. Sharks are not friendly toward humans or any other meat so you cannot swim with them safely, Whales of some species may let you swim or ride them for brief periods. Sharks have no language or communication that we know of, Whales make noise of many kinds and sing to one another over distances. Sharks will eat other sharks, whales do not eat each other. Sharks are rarely found washed upon beaches, whales beach themselves due to old age, death, and sometimes poisoning of the water where they live. Sharks do not spawn or migrate seasonally, Whales travel in groups with seasonal patterns. Sharks do not surface to breathe, Whales must surface regularly. Sharks as far as we know do not drown, Whales can drown in open waters. Sharks have been known to grow as large as an average the Blue Whale, Whales are ten times larger generally than the average Great White Shark. Sharks do not like bright light, Whales are not generally bothered by light. Sharks do not technically hear for they have no ears, but do use a kind of sonar location, Whales have both sonar and auditory capabilities but do not have ears. Sharks warn their presence when their dorsal fin cuts the water but do not seem to be aware of this factor but for sonar, Whales generally do not need to warn of their presence but when provoked are keenly aware of their size and will use their bodies and tales destructively if necessary. Sharks have jumped aboard tuna schooners to attack both fish and fisherman, whales do not usually jump out of the water unless at Seaworld and being fed a fish. Sharks are said to be vulnerable to a punch directly in the nose to avoid an attack by one, Whales I do not believe have this same vulnerability. Sharks can attack and kill at one day old, Whales probably can as well. Sharks are most closely related to ancient Great White Sharks and have not changed at all in almost two million years, Whales are most closely related to Whales and their land roaming cousin the Elephant. Sharks have an endless supply of teeth that grow back in days no matter how many are lost, Whales were hunted for their bones and teeth and some have tusks like Elephants. Sharks do not have horns of any kind, the Narwah Whale has a twenty foot tusk that spirals sometimes making them look like a unicorn of myth. Sharks and Whales have never been mistaken for unicorns. Sharks have nearly razor sharp skin that can rip liferafts and break more dense materials by scuffing up against it, Whales have died due to being hit by large ship proepllars and are hunted with harpoons. Sharks are not hunted for sport (and only minorly for their actual meat ) yet they elevated weapons technology by forcing man to invent the only propelled water rifle the speargun, whales are are no longer allowed to be hunted but were still always hunted with nets and harpoons. The Eskimo do not nor have ever hunted for Shark, the eskimo hunted the Orca Whale. The Mayan civiliztion had records and history that they knew what Sharks were, they do not have any history or make knowledge of Whales. The Egyptians had recoreded knowledge of the existence of Sharks, the Egyptians do not have recorded knowledge of the existence of Whales. The Vikings had recorded knowledge of both Sharks and Whales. The Chinese and Japanese knew of the existence of both Sharks and Whales. Jonah was a Jew, and one of the only recorded events in ancient history when someone was said to have been swollowed rather than eaten by a sea creature - but although sunday school teachers call the story Jonah and the whale, the Bible says 'the great fish'... it is unlikely a Shark would swollow for the usually bite apart their prey anyone and then spit them out, a Whale is a more likely to be unaware that it swollowed something as large as a human and could have done this - we just don't know about that one for sure. Sharks are reported about on television news yearly more than any other sea creature due to attacking humans, Whales have only on televsion news when doing tricks for the cameras at seaworld, beaching themselves to die. Sharks will hunt a human if it they are cut and bleeding, Whales do not hunt humans. Sharks have made more money at the box office in raw sales (Jaws), Whales have made more money in the video/dvd/and rental sales of their movies (Free Willy). Sharks appeared just barely more minutes of time on the camera than Whales on all the episodes of Jacques Cousteau. And lastly a Whale Shark is a shark, not a Whale.

No actual Sharks or Whales were harmed in the production of this Hub. We respect all species equally despite their willingness or intentions about eating humans

Wow, you must just be doing this from what you have heard and not verified. You over generalize the characteristics and behaviors of both animals. Many whales and dolphins do hunt for their food. Ever heard of a Killer Whale? An are ou actually claiming that sharks are not hunted for sport? Why do you think sharks are now struggling? Oh wait, you don't. Nice try buddy, but check your facts next time.

I appreciate your opinions Hd, you may be right, I am no marine biologist nor do I claim to be. And I would only point out that this was a contrast and comparison essay, but I did verify all the stated facts with the Cousteau society documentation, and several other websites that are used for verifying information on such comparisons. Google the title of my essay and you will find the American Oceanongraphic and Marine Biology Sciences forums. Which list the facts in greater degrees. Oh and technically, and Sharks are not on the Endangered species lists. Very few marine predators are yet...unless you are talking about since the Gulf oil spill. An event which happened many months after I wrote this article. But I am no expert, but it sounds like neither are you. Thanx for reading my hub. Keep on Hubbing. Blake4d

I seen a lot of wrong info. Sperm whales are toothed whales that hunt Giant Squid. orcas have been known to hunt and kill great white sharks like the orca that killed the shark by the farralons off the cost of California and NO animal has ever exceeded the size of a blue whale not even megalodon the largest shark ever. And sharks are the only fish that give birth to live young. Oh yeah sharks are not omnivores all of them even whale sharks are carnivores. I forgot sperm whales also been known to kill sharks. Dolphins belong to the toothed whale family.

Not all whales are endangered. Sharks do not hunt humans. First we do not have a lot of fat like seals and sea lions not even the most obese person and second sharks are unable to digest human flesh and we do not taste to well. Sharks attack humans MOSTLY because they mistake us for food or territory. And whales have much larger brains than sharks because sharks brains are mostly devoted to smell. I'm a marine biologists and so is Joey we got to UCSD. really to be real humans are apex predators despite us being preyed on by weak big cats such as jaguars, tigers, lions, and occasionally leopards. It's mostly because we are not armed with weopons and the animal is weak and can't afford to risk its life to hunt larger stronger prey items.

I appreciate both of your more educated points of view. I did verify all the stated information with the Cousteau society documentation online, and several other websites that are used for verifying information on such comparisons. Google the title of my essay and you will find the American Oceanongraphic and Marine Biology Sciences forums have the information I listed. But that does not mean that the online documentation is accurate. I said that the squid was a natural predator. I said the Blue whale was the largest. No mammal has exceeded that size, you are forgetting prehistoric reptiles and varieties of deep sea squid. Sharks may give birth to live young, but they do not raise them. They do not school like other fish, in fact to simply call them a fish is to neglect that sharks are relatively unchanged since the ceneezoic era. And you are wrong sharks are omnivores. All whales are on the endangered species lists. Name one that is not. Sharks are even on the endangered lists since the BP oil spill. Sharks and polar bears are the only animals that will hunt humans, check that for yourself. It is true, but I will give you the blood is what sparks frenzy feeding. They do not mistake us for food. They are omnivores. They will eat other sharks, metal, rock, anything when feeding. Whales have much larger brains due to their size and being mammals. Sharks have smaller brains due to being reptilian or prehistoric on the evolutionary ladder. Their brain is specialized but due to lack of change evolutionarily for millions of years. Yes devoted to smell, but it is evolution not species and genus that is the cause of that. Jungle cats rarely ever attack humans, if they did it would be because they were starving in their enivironment. Polar bears and sharks are the only creatures that will hunt humans based on smell of blood, they will track humans as well. But since you are (experienced?) marine biologists, I am sure we could argue all day. And Dolphins were only brought up as natural predators. Anyway, you did not think this hub was written to be an absolute authoirty on the subject did you, for the most part the information was presented in a most basic format for the novice, and some was humorous as well. Thanx for reading anyway. Keep on Hubbing. Blake4d

Joey 4 years ago

No sharks are not omnivores they may eat anything like tiger sharks eat license plates but they are classified as carnivores and orcas which are not considered whales they actually kill other whales hence the name "killer whale" but they still belong to the family and are not endangered. And the giant squid is not the natural enemy of all whales. Most whales live near the surface not in deep waters giant and collosal squids live 2 miles below the surface. Sperm whales are the only mammals that can hold their breath for 2 hours and dive at such great depths. The beluga whale is not endangered either.


Geared 4 years ago

Really the real natural predators of humans are tigers, crocodiles, and lions. Like I already said sharks CANNOT digest human flesh. And no animal has grown larger than the blue whale. And the real natural predators to sharks and whales is the orca. A large shark or even a whale is no match for the orca? When a shark is being killed the orca uses a strategy called tonic immobility. And I've been studying the history of theses creatures for almost 8 years

blake4d 4 years ago from Now Rising Out of Phoenix Arizona Earthlings Author

As I said Joey and Geared, perhaps you should be writing, rather than wasting your energies just being a comment and critic. Classification often deviates greatly when you observe behavior in the natural environment. All whale species are endangered now due to the last thirty years of pollution and contamination of the oceans, and sharks are omnivores behaviorally. Genus, class, species, as a whole is what you have to look at scientifically. But as I said before, you should be writing somewhere, not wasting your time debating. The beluga whale is endangered, why do you think there are laws against over hunting them? You should write your own webpages and give your perspectives, I appreciate that every time you go back to this page that I am getting paid for it. You should be too. And I certainly did not claim to be an expert, I did research, all of which was available at the sources I stated. All scientific knowledge eventually becomes obsolete and disproved. Keep on Hubbing.

Honey 4 years ago

Beluga whales are in the near threatened category not endangered. And jungle cats do prey on humans and you are more likely to be killed by your dog than a polar bear.

This explains some of what I am trying to say better. There is a link at the bottom that is where it is cited from. Good luck to all of you.

SYSTEMATICS AND PHYLOGENY

Continued speciation will generate groups of closely related species. A clade is a group of species that includes an ancestral species and all of its descendants (Figures 3, 4). Clades (also called monophyletic groups), like species, are formed by the process of descent with modification. A phylogeny is a pattern of common ancestry reflecting this evolutionary process. We call our own "family phylogeny" a family tree (Figure 2) or a genealogy; the terms all refer to the same type of pattern generated at different scales by the evolutionary process of common descent.

Phylogenetic Inference

Because species and clades originate over evolutionary time scales, by the splitting or branching process inherent in reproductive isolation (Figure 3.1), we cannot observe their origination directly. Instead, we must infer the relative timing of origination of species by comparing features that they possess. How do we decide which species are closest? And especially how do we decide which species branched off from which? We use special methods of phylogenetic inference, developed over the last several decades, to compare features present in a given group of species to allow us to figure out how they are related to one another. These methods are based on the same simple principle that we use unconsciously to guess at human family relationships. Closely related individuals tend to share a larger number of similar features than do distantly related individuals, as a result of their shared common ancestry.

RETURN TO TOP

Is a whale more closely related to a human or a shark? Even though whales and sharks both share certain features of overall body form, by following phylogenetic methods of observation and comparison (discussed in more detail below), we conclude that whales and humans actually have many more detailed features in common (see Figure 7) than do whales and sharks. This can be explained by the fact that whales share a more recent common ancestry with humans (Figure 4) than they do with sharks. We predict that their closer relationship means that they share more features in common, and the evidence supports this prediction. Similarities between whales and sharks are largely superficial and result from their common aquatic habitat, not from their descent from a common ancestor. Phylogenetic systematics is the name of the field of study in which genealogical relationships among species and clades are discovered. Systematists practice systematic methods of reconstructing phylogenies in order to understand the pattern and process of evolution.

Cladograms and

Phylogenetic Trees

Phylogenetic patterns generated from branching processes may be represented in at least two different ways: cladograms and phylogenetic trees. Cladograms are branching diagrams that illustrate patterns of phylogenetic relationships. The pattern of branching itself is the focus of a cladogram; the relative lengths of branches in cladograms have no special significance (Figure 4). Time is included in cladograms only in a relative sense, in the internested structure of the cladogram itself. For example (Figure 4), we see that sharks originated before whales, but cannot tell from the cladogram how long before. Phylogenetic trees are branching diagrams that illustrate both branching patterns and time; branch lengths have meaning in the sense that longer branches imply longer periods of time (Figure 5). We can think of both cladograms and trees as phylogenetic maps. Both express hypotheses about a phylogeny — a pattern of evolution.

RETURN TO TOP

Cladograms are reconstructed by comparing the distribution of characters among species. Characters are inherited attributes of organisms; they may be morphological, genetic, developmental, behavioral, physiological, biochemical, and so forth. Hair color, leg length, or gene sequence, for example, are characters of organisms that vary. The variation can be characterized by counting or measuring or describing it. Character states distinguish different variations of a given character. Red, blonde, or black are different states of the character "hair color."

Examining Characters

There are two types of characters in phylogenetic inference — homologous characters "tell the truth" about phylogeny, and homoplastic characters are deceptive about phylogenetic relationships. Homologous characters share common ancestry (Figure 4 and Table 1), and for this reason they are useful in reconstructing phylogeny. They are often, but not always, similar to one another in appearance. Homology of two states can be tested by comparing the development and location of the features on organisms. Hair, for example, develops in the same manner, from the same kind of cells in the skin in all mammals. Hair is homologous in cows, bats, humans, and all other mammals.

Homoplastic (analogous) characters may also be similar in appearance, but have actually evolved from different ancestors. Homoplastic characters can distort patterns of relationship indicated by homologous characters because they are often in conflict with them. Octopus eyes and human eyes are homoplastic; they develop very differently and have evolved independently in two remotely related groups of animals. Body form in whales and fishes is homoplastic and relates to their aquatic mode of life (Figure 4). Wings in birds and bats have evolved separately in each group; these features are homoplastic as wings. However, they are homologous as forearms, because they evolved in each case from the front limbs.

Characters change from one state to another through the process of evolution. The initial (old) state is said to be ancestral (or plesiomorphic); the new or novel state is derived (or apomorphic) relative to the ancestral state. For example, brain to body size ratios increased in human evolution. Relatively smaller brains are ancestral, relatively larger brains are derived. Closely related organisms share derived features, such as feathers shared by birds. Characters shared through common ancestry (homologues) and derived relative to a former state are called shared derived characters or synapomorphies. Species and clades are defined by these new features because they are more informative than shared ancestral characters (symplesiomorphies). Fully upright posture, walking on two legs, the development of language and culture, and perhaps the ability to use tools distinguish us from both of our closest living relatives, the gorillas and chimps.

Suppose we tried to define human beings by the possession of hair. Hair is homologous among all mammals, shared by common ancestry, so it is not a deceptive, homoplastic character that we would automatically avoid using. However, hair is a shared ancestral character for humans. Because it is also shared by many non-human mammals, it doesn't help to distinguish humans from other mammalian species, and is a pretty useless diagnostic character.

Character Polarity

The direction of character change in evolution, from ancestral to derived, is referred to as character polarity. It is not always obvious which character states are derived and which ancestral. Some criteria for determining the direction of character change in evolution must be established. Ancestral and derived states are always identified as such by comparison to a frame of reference (Figure 4, Table 1). Of several possible character states (e.g., hair present, hair absent), the ancestral state is the one present in a closely related species outside the group of interest (outgroup criterion), or the one appearing lower in the stratigraphic record (paleontological criterion), or earlier in development (ontogenetic criterion). Because ancestral and derived states are determined relative to some reference frame, their status changes if the frame of reference changes. Hair is derived for mammals (relative to other [non-mammalian] vertebrates), but ancestral for humans, because the closest relatives to humans, gorillas and


blake4d profile image

blake4d 4 years ago from Now Rising Out of Phoenix Arizona Earthlings Author

gorillas and chimps, also have hair. Consider whales, which have very minimal hair. Does their apparent lack of hair mean that whales are not mammals? No. Because of many other shared derived characters of mammals that whales possess (for example, giving birth to live young and nursing their young), we conclude that whales are mammals that no longer need much hair for their fully aquatic mode of life. Loss of hair is thus a derived feature for whales, among the mammals.

To summarize, all living things are related to each other, more closely or more distantly. This relative pattern of relationships can be expressed in a vast, nested hierarchy — the hierarchy of life — represented in a series of internested cladograms. The possession of certain features (homologues) can help locate the position of an individual in the hierarchy of life. Closely related individuals tend to share a larger number of similar features than do distantly related individuals as a result of their shared common ancestry. Establishing the pattern of character distribution among individuals and among species and higher taxa can therefore reflect and reveal the process of common descent with modification — the process of evolution.
