Pleurobranchus peroni from Sth Africa

December 7, 1999
From: Valda Fraser

Dear Bill
I don't know if this is a nudibranch or not. It lives under broken bits of coral and rocks. The size variation I have seen is from 20mm - 80mm. I look forward to your response.
Locality: South Coast KwaZulu - Natal, SOUTH AFRICA. Scottburgh - Rocky reef - 24m. November 1999. Size: 70mm

Regards

Dear Valda,
This is a pleurobranch not a nudibranch. Have a look at the other species of the Order Notaspidea in the Species List to get an idea of the variety. They are sometimes called 'side-gilled slugs' because their gill is hidden below the mantle skirt on the right side of the body.

I'm pretty sure that this animal is Pleurobranchus peroni. If you look at the Top of the Page you will see I think a lot of the names given to South African pleurobranchs are colour forms of this species.

Best wishes,
Bill Rudman.
