Ctenophora
commonly known as Comb jellies
Ctenophores are one of the most beautiful creatures that exist. Their bioluminescence comes in a variety of forms. Their anatomy consists of eight comb rows of fused cilia on the sides of the animal, as can be seen as the red in the picture. The cilia beat in synchronization and propel the Ctenophores through the water. Ctenophora are also called "sea gooseberries", "sea walnuts", or "Venus's girdles." Don't let their soft shape or cute nicknames fool you, they are strong predators that capture prey through sticky cells called colloblasts. In a few species, special cilia in the mouth are used for biting gelatinous prey. Though if you do see them in the ocean, they don't sting and feel a bit like thin rubber against your skin.
