The body forms of nudibranchs vary enormously, but because they are opisthobranchs, unlike most other gastropods they are bilaterally symmetrical because they have undergone secondary detorsion. Most species have venomous appendages on their sides. These are used to deter predators. Many also have a simple gut and a mouth with a radula. They lack a mantle cavity. Their eyes are simple and able to discern little more than light and dark.The eyes are set into the body, are about a quarter of a millimeter in diameter, and consist of a lens and five photoreceptors Nudibranchs have cephalic (head) tentacles, which are sensitive to touch, taste, and smell. Club-shaped rhinophores detect odors.
