Nudibranch. Some of the most colorful creatures on earth! There are more than 3,000 of these shell-less mollusks in the world’s oceans. They range in size from a quarter of an inch to up to 12 inches long. Why so colorful? They get their colors from the food they eat like coral, fish eggs, sponges and sea anemones. . . . . . . . . . #Nudibranch #animallover #animalplanet #wildfacts #animalkingdom
