Sea life: Crowned nudibranch

The crowned nudibranch (Polycera capensis) is identifiable from the six yellow projections from its head (clearly visible above), black gills, and yellow projections on each side of the gills (also visible above). It has a white body with black, yellow and/or orange stripes, but these may be absent or occur with varying intensity.

These nudibranchs eat bryzoans, like many of their relatives, and lay wavy white egg ribbons. They can grow to 5 centimetres in length, and are found from Namibia to Port Alfred. They are relatively common (by which I mean, I see them quite frequently).
