The Sea Mouse is a type of marine polychaete worm belonging to the family Aphroditidae. It is known for its unique appearance, featuring a dense covering of bristles that resemble fur. These bristles can reflect light, giving the sea mouse a shimmering look. Sea mice typically inhabit sandy or muddy ocean floors and can be found in various marine environments. Sea mice are primarily scavengers, feeding on organic matter and detritus. They have a flattened, elongated body that can reach lengths of up to 10 inches. The species plays a role in the ecosystem by helping to break down and recycle nutrients in the ocean, contributing to the health of marine habitats.
