Deadly and Dangerous Ocean Creatures
The Wonder of Our Oceans
The Oceans comprise 70% of the Earth's surface! An yet only a small fraction has been discovered. We are the intruders in the underwater world. There are thousands of marine animals, both good, bad, and ugly. We simply need to be vigilant and respect the life below. A good rule is "look but don't touch." They give us oxygen while absorbing 50 times more carbon dioxide. Yet they can be 'angry,' giving us hurricanes, rouge waves, floods, and tsunamis.
There are dangerous and deadly marine life to avoid at all times. Here is a list of the ten deadliest ocean creatures:
- Tiger Sharks
- Sea Snakes
- Great White Shark
- Great Barracuda
- Blue-Ring Octopus
- Box Jellyfish
Ten Venomous Ocean Creatures
The deadliest and most venomous sea creature is the box jellyfish, also known as the "marine stinger or "sea wasp." The toxicity of the jellyfish and its small stinger is one of the fastest actions in nature. The stingers shoot out even after faster than a bullet from a gun. A box jellyfish can kill a human in two minutes. Found in every ocean and some in freshwater lakes and ponds. They can be as small as a thimble or as large as eight feet with tentacles reaching 200 feet. The tentacles are armed with cnidoblasts, and inside are nematocysts that contain a coiled stinging thread.
Jellyfish are 95% water, and if removed from the ocean, they collapse and die.
There are over 2000 different types, and about 70 can harm humans. They move by taking water in their 'bell' and squirting it out behind them. It is believed shipping has inadvertently distributed them worldwide, allowing them to become invasive. They are able to adapt even in dead zones, and there are hundreds of dead zones in our oceans. In Florida alone, some 200,000 stings are reported each year, and in the Chesapeake Bay, some 500,000 stings.
A venomous creature that lives in tide pools and coral reefs. Found in the Pacific, Indian Oceans across Japan and Australia. Their lifespan is two years. The females die after incubating about 50 eggs. Their venom is capable of killing 26 adults in minutes.
They have enough toxin to kill 30 adult humans. They are edible, but extreme care must have special preparation.
They threaten native fish and are invasive along the east coast and the Caribbean. They are venomous but not poisonous and can be eaten and taste similar to lobster and shrimp. Their lifespan is 10-15 years.
One of the most dangerous sharks and found in shallow reefs, harbors, and canals. They are near extinction because of the hunt for their fins, flesh, and liver.
They are poisonous and prefer shallow waters and found in the Indian and Pacific Oceans. Appear to be nervous, but their injections are rare against humans..
Great White Shark.
They are found in all major oceans and are responsible for more attacks on humans than any other shark. As of 2010, it is estimated fewer than 3500 exist and are vulnerable to extinction.
They are disk-shaped with a flexible armed tail with saw-edged spines. They rarely kill humans, but the sting can cause acute pain. Their habitat is coastal and subtropical regions. Out of 220 species, 45 are vulnerable to extinction.
With their excellent camouflage, they are hard to spot. Found in tropical waters in the Indo-Pacific and are bottom feeders hiding among rocks or coral. Should you step on one, soak in hot water and seek medical help immediately.
Predators that hunt by ambush with their habitat found in the subtropical oceans around the world. Usually swift but rarely harmful.
