Cratena peregrina from Senegal

July 16, 2003
From: Marina Poddubetskaia

Dear Bill,

I can confirm for you that Cratena peregrina is very common in Senegal: I saw this species in most sites.

I didn't see any Cratena peregrina laying eggs, but I found an hydroid with many Cratena on it and with several egg-ribbons like in second photo. Of course, we can't be 100% sure it belongs to this species, but I think it is likely to be. Next week I will go to Cerbere and try to see if Mediterranean Cratena have the same egg-ribbons.

Cordially,
Marina.

Thanks Marina,
The egg mass looks very similar to the one in Erwin Koehler's photo. I have included a close-up of the head alongside to show some detail of the colour pattern.
Best wishes
