Why manatees are in trouble: Purple-striped jellyfish taken off the coast of Monterey, California. These bacteria are capable of chemosynthesis and live inside the giant tube worm, which lives on hydrothermal vents. Scientists believe these creatures are much larger than shallower-water tube worms because they live on hydrothermal vents that expel huge amounts of resources.

A marine biologist, Jeffery Drazen, has explored a solution, a pressurized fish trap. Organisms can also use chemosynthesis to attract prey or to attract a mate. Cover with talcum powder or shaving cream, let it dry and then scrape it off.

In fact they are an important part of the ocean's ecosystem. They consume up to a quarter of their body weight every day.

The greatest enemy of tuna is overfishing, overfishing, overfishing, as well as tuna ranching when tuna are caught alive and fed for months before being exported and loss of prey. But it never actually disappears—it just lurks in the environment, waiting for scientists to come looking for it.

Why Hector's dolphins are in trouble: Clinging to seaweed, their transparent bodies are almost invisible to the tiny fish and shrimp who may blunder into the gaping trap.

The good news is that fishing restrictions have allowed the third population, in the Eastern North Pacific, to rebound to the point that it was removed from the U.

Why are cape penguins and other sea birds in danger.

Ocean Pollution: Even Sea Creatures in the Deepest, Darkest Trenches Are Full of Plastic

Loggerhead Sea Turtle image link Loggerhead sea turtles, like all six types of sea turtles, are listed as threatened with extinction under the Endangered Species Act. Its advanced telescope-like eyeballs allow it to spot even the tiniest prey in the surrounding water, which it slurps up with that tubular trunk.

Just a few meters below the waves, marine biologist and explorer-photographer David Gruber discovered something amazing -- a surprising new range of sea creatures that glow in many colors in the ocean's dim blue light. Join his journey in search of biofluorescent sharks, seahorses, sea turtles and more, and learn how these light-up creatures could illuminate a new understanding of our own brains.

The ocean is full of wonders and plants that are beyond imagination. But these 20 sea creatures are so weird looking that it's hard to believe they're actually real, although we swear they really are.

When you simply can't get enough of the Walrus and the Carpenter, Boat Street, or Whale Wins restaurants, order their pickles, t-shirts, or totes!

Scientists have used a variety of methods to estimate the global number of marine species and each has its limitations.

Data isn’t always reliable and the assumptions of each method can be flawed. See photos of colorful sea creatures (including sea stars, clownfish, nudibranchs, and more) in this ocean photo gallery from National Geographic. These strange sea animals will interest and inspire you.
