What animals live in the Indian Ocean?


Quick Answer

The Indian Ocean, like many of Earth's oceans, serves as home to a diverse number of species, including anenomefish, Great White sharks, bottlenose dolphins, blue whales, sea turtles, jellyfish, stingrays, sea anemones, sea snakes, worms and stonefish.

Animals in the Indian Ocean cover many major groups, including warm-blooded and cold-blooded organisms, shellfish, fish and crustaceans. Some, like the stonefish, Portuguese Man-O-War, lionfish and cone shells appear as attractive and benign organisms, but they pack lethal poisons. Portuguese Man-O-War, which form from colonies of polyps, contain long, stinging tentacles. They bear some resemblance to Sea Nettle, a potentially hazardous pale pink jellyfish.

While these animals live in deeper waters, others reside closer to shorelines and reefs. Stonefish, anenomefish, lionfish and Blue Devils, for instance, prefer shallow waters. Stonefish blend into their surroundings with a sand-colored outer skin. Clown anenomefish contain blood with lethal toxins; in an opposite survival tactic, they boast bold and beautiful colors, warning predators of their toxicity. Other Indian Ocean inhabitants include moray eels, several species of rays and barracuda.
