Aphrodita, or sea mouse, is a genus of marine polychaete worms found in the Mediterranea sea and the eastern and western Atlantic Ocean.[2]
Etymology
The name of the genus is taken from [[Aphrodite ]], the Ancient Greek goddess of love. This is because, when viewed ventrally, the animal resembles a human female's genitalia. The English name may either have a similar meaning, or may derive from the supposed resemblance to a bedraggled mouse when washed up on shore.[3]
Description
The body of the sea mouse is covered in a dense mat of parapodia and setae (hairlike structures).[2] Adults generally fall within a size range of 7.5 to 15 centimetres (3.0 to 5.9 in), but some grow to 30 centimetres (12 in).
Structural coloration
The spines, or setae,[2] on the scaled back of the sea mouse are one of its unique features. Normally, these have a deep red sheen, but when the light shines on them perpendicularly, they flush green and blue, a "remarkable example of photonic engineering by a living organism". This structural coloration is a defense mechanism, giving a warning signal to potential predators. The effect is produced by many hexagonal cylinders within the spines, which "perform much more efficiently than man-made optical fibres".[4]
Feeding
Aphrodita are typically scavengers.[2] However, Aphrodita aculeata is an active predator,[5] feeding primarily on small crabs, hermit crabs and other polychaete worms including Pectinaria and Lumbriconereis.[5]
