Description

Cratena peregrina is a nudibranch of 2 to 5 cm, translucent body covered with bright-blue cerata tipped in orange. Lives on hydroid colonies on which it feeds, storing their stinging cells (nematocysts) in its own cerata for defense. A spectacular macro subject. Very common in the Mediterranean and nearby Atlantic in spring and summer.
