Annelids are found worldwide in all types of habitats, especially oceanic waters, fresh waters, and damp soils. Most polychaetes live in the ocean, where they either float, burrow, wander on the bottom, or live in tubes they construct; their colours range from brilliant to dull, and some species can produce light. The feather duster (Manayunkia speciosa) inhabits the Great Lakes and some rivers of the United States.
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.
