Tiger Favorinus Nudibranch - Favorinus tsuruganus

This Tiger Favorinus Nudibranch - Favorinus tsuruganus are very small in size, less than 1 cm.
They got the name for their yellow/orange colour and their voracious manner of feeding of the eggs of other species of Nudibranch.
In this picture, there are 4 of them, feeding on the egg ribbon/mass of another nudibranch, that is that whitish stuff. Sometimes, even while the other Nudibranch are still laying their eggs, this Tiger Favorinus can already be seen on the egg ribbons feeding.
