a swimming mollusk with dozens of tiny blue eyes that sees you coming and bolts

means A marine bivalve mollusk with a distinctive fan-shaped, ribbed shell, prized as seafood — or, by extension, the wavy, curved edging shaped like that shell.

from From Old French 'escalope,' meaning a shell or shell-like covering, which is probably of Germanic origin, related to words for 'shell' or 'husk' (think of the same family that gives us 'scale' and 'shale'). The shape was so iconic that 'scallop' came to mean any rounded, wavy edge — and the verb 'to scallop' followed, for cutting cloth or pastry into those little curves.

eyes: Up to 200 eyes line the shell edge
mirror vision: Eyes use crystal mirrors, not lenses, to focus
jet propulsion: Claps shells to swim away from predators
the meat: Edible part is one oversized swimming muscle
sex life: Many are both male and female at once
