Question

This nudibranch, a type of sea slug, has many reddish cerata on its dorsal surface, as well as two. white-tipped rhinophores located on the head. The general term sea slug includes a wide variety of marine gastropods. One feature they all share as adults is the lack of a shell. As a result you might think they represent defenseless morsels for predators. In fact, sea slugs have multiple defenses. Some sea slugs prey on sponges and concentrate sponge toxins in their tissues. Others feed on cnidarians, digesting everything except the nematocysts, which they then transfer to their own skins. Whereas the most brightly colored sea slugs are often highly toxic, others are nontoxic and mimic the coloration of the toxic species. Their colors are mostly derived from pigments in their prey. There are also sea slugs that use their coloration to blend into their environments. Based on the above information, sea slugs can most likely obtain nematocysts by preying on Sea urchins Sea stars Sea cucumbers Sea anemones Sea lilies Nudibranchs. a type of predatory sea slug, can have various extensions on their bodies specifically on the dorsal surfaces. Rhinophores are paired structures, located close to the head, which bear many chemical receptors (chcmoreceptors). Dorsal plummules, usually located posteriorly, perform respiratory gas exchange. Cerata usually cover much of the dorsal surface and contain nematocysts at their tips. The stingers of honeybees have a function most similar to that of rhinophores dorsal plummules cerata all of the above none of the above
