Question

Quizplus · Accepted Answer

Radula modification in gastropods allows for scraping food such as algae off of rocks (A) and eating vegetation (B). It can also be modified for boring holes in other mollusk shells (C) and for injecting poison through a harpoon-like structure (E). However, it does not protect gastropods with nematocysts (D); rather, nematocysts are found in cnidarians such as jellyfish and corals.
