Dolphin Lovers Dream
Are Dolphins Mammals? Or Fish? What do Dolphins Eat?
Lots of people think dolphins are fish but NOPE - a dolphin is actually a mammal.
Dolphins (and whales) have all the features of a mammal: they are warm-blooded, give birth to live young (rather than laying eggs) also they breath air using lungs (not gills like fish). They also feed their young milk and even have fur, though not very much. So whales and dolphins are mammals, but sharks are fish.
What do dolphins eat? Dolphins are predators. They eat fish, squids, octopus, jellyfish, shrimp and other crustaceans. Dolphins have teeth but don't chew their food. They just grab with their teeth and swallow. There's more than one species of dolphin and each eats a little differently. Some of the largest dolphin species will even sometimes eat large marine mammals like seals or sea lions and sometimes turtles.
Are Dolphins and Porpoises the Same? NO
They may seem the same but they're not. Both dolphins and porpoises are air-breathing, warm-blooded marine mammals, and they do look similar. However dolphins and porpoises are a very different species, about as different as a cat and a dog.
To get good at telling the difference, look closely at the mouth. A dolphin's mouth is much longer. Also the dorsal fin - dolphins have a curved fin, while porpoises have a triangular dorsal fin. The dolphin's body is usually much leaner than a porpoise.
Dolphins - the Smartest Creatures on Earth
Are you smarter than a dolphin? What can we learn from dolphins?
Many scientists and marine biologists consider dolphins to be the most intelligent animals on earth. Did you know that dolphins can hear frequencies ten times or more above the upper limit of adult human hearing? They also have acute eyesight, both in and out of the water. Beyond these acute sense organs, the dolphin brain is able to communicate with humans in ways uncommon to ANY creature in the animal kindgom.
Science has even shown that..."dolphins have a proportionately larger brain than humans and in some ways far more developed, that they have clearly identified and highly developed emotions such as joy, compassion, humor and emotional self-control, that they live in large complex social groups that live in great harmony."
Dolphins intrigue people, perhaps because we relate to their intelligence and playful spirits. A dolphin is considered a symbol of freedom, joy, serenity and grace.
True Stories of Dolphins Rescuing People
There are countless true stories about dolphins rescuing people and treating humans with joy and respect. In Greek times, dolphins were so respected for their help to mariners that killing a dolphin was punishable by death. Some even say that dolphins and angels are related, and refer to dolphins as the 'angels of the sea' as their loving and protective nature reminds of of angels. There is even some esoteric and mystical new age information about dolphins that indicates they are indeed not only ancient, but such highly evolved creatures as to perhaps not even originally from this earth.
