Question

Quizplus · Accepted Answer

Bilaterians are animals with bilateral symmetry - meaning their left and right sides are mirror images of each other. While adult starfish may not appear to have this symmetry, their larvae do have bilateral symmetry. Additionally, starfish have an anus that forms from the first opening in the embryo, which is a characteristic of bilaterians. Therefore, choice B is the best answer as it covers both of these characteristics.
