Detailed explanation-1: -Ctenophores are called as ‘comb jellies’. It is a gelatinous animal that drifts through the ocean’s water column around the world. Comb jellies are named for their unique features like, plates of giant fused cilia, known as combs, which run in eight rows up and down their bodies.

Detailed explanation-2: -Ctenophores, variously known as comb jellies, sea gooseberries, sea walnuts, or Venus’s girdles, are voracious predators. Unlike cnidarians, with which they share several superficial similarities, they lack stinging cells. Instead, in order to capture prey, ctenophores possess sticky cells called colloblasts.

Detailed explanation-3: -They are named as Comb jellies, for their combs-the rows of cilia, lining their bodies that propel them through the ocean. They are walnut shaped and hence known as sea walnut.

Detailed explanation-4: -The gelatinous comb jellies are members of the phylum Ctenophora, meaning “carried by combs.” These gelatinous animals are the biggest organisms that swim by moving cilia, hair-like structures lining the walls of their bodies. Though they aren’t true jellyfishes, the similarity is uncanny.
