You are working as a marine biologist off the coast of Mexico. While observing organisms in a tidepool, you find a dramatically colored animal that has not been classified before. Your observations lead you to think that this beautiful animal is apparently a nudibranch, which is a member of the mollusk phylum. However, you are puzzled by one feature that does not fit with the other anatomical and
physiological features of mollusks: stinging nematocysts in the external projections on the back of this animal. Explain how this animal might be correctly classified and what the supporting logic is.
What will be an ideal response?
Members of the nudibranch group, within the mollusks, are known to eat members of the cnidaria phylum. They can then store the unused stinging nematocysts in their external respiratory organs. They can be used later as a defense mechanism.
