• Norwegian: korallsnegl

Characteristics:

This is not the most common sea slug in Norway, but certainly the biggest one, reaching a length of 20 cm sometimes. A typical feature is all the gills along the edge of the mantle. On the head it has branched rhinophores. Juveniles are often white or colored in pale shades, while adults may be mottled in vivid colors like brown, yellow or orange.

You should not touch this slug, as it can give blisters. These are caused by a secretion in warts on the mantle.

Habitat:

The Tritonia hombergii's main diet is the soft coral A. digitatum, and thrives on the same current exposed locations. The usual depth range is from the subtidal zone and down to 80 metres.

Distribution:

This nudibranch is known from north-west Europe, from Norway to Spain.
