Pleurobranchus forskalii in South Africa

April 17, 1999
From: Ernest C.J. Seamark

One specimen of Pleurobranchus forskalii was collected from within the intertidal zone of Treasure Beach, 6km south of Durban Harbour mouth, KwaZulu Natal, South Africa. On the 5 October 1998. If the ID is correct then this is the first record for South Africa, as it has been previously been recorded from Inhaca Island. [The lower photo is of the foot].

Please could you email your reply as I find it difficult to access the net and therefore the sea slug forum.

Dear Ernest,
This is indeed Pleurobranchus forskalii. I guess like in New South Wales, here in eastern Australia, your are going to find tropical species some years, depending on the vagaries of the currents and water temperature.

Best wishes,

Bill Rudman.
