Spanish Shawl Nudibranch with Eggs

Description

This Spanish shawl hangs upside down as it lays a rope of pink eggs on the underside of the reef. Its purple body, orange cerata and red rhinophores all get their color from one pigment, astaxanthin, taken from the hydroids it eats. Unlike most other nudibranchs, it can swim, bending its whole body back and forth into a U.
