The blobfish (Psychrolutes marcidus) is a deep sea fish of the family Psychrolutidae. It inhabits the deep waters off the coasts of mainland Australia and Tasmania, as well as the waters of New Zealand.Blobfish are typically shorter than 30 cm.They live at depths between 600 and 1,200 m (2,000 and 3,900 ft) where the pressure is 60 to 120 times as great as at sea level, which would likely make gas bladders inefficient for maintaining buoyancy.lobfish are often caught as bycatch in bottom trawling nets. Scientists now fear the blobfish could become an endangered species because of deep-ocean trawling.
Clown fish live on the ocean floor. They are found in the warm waters of the Pacific Ocean, the Red Sea, the Indian Ocean and Australia's Great Barrier Reef.lown fish find most of their food by mooching off the anemone. Clown fish wait until the anemone paralyzes and eats a fish, then helps itself to the bits which the anemone doesn't eat. Clown fish avoid being harmed by the anemones by swimming a funky dance around the anemone's poisonous tentacles.
