Spurilla major from Korea

From: Dong Bum Koh


Dear Bill,

May I introduce a seaslug from Korea.  It is the first time I have seen it here and I suspect it is Spurilla major.
It was taken on the southern coast of the Korean penninsula.

Locality: Tong Young City, -14 m, Kyung Nam Prov., South Sea of Korea, 20 Oct. 2007, Sea weed. Length: Approx. 30 mm. Photographer: Jeong Guwon Park.

Best regards,
Dong Bum Koh

Dear Koh,

I a pretty sure it is Spurilla major, which is quite variable in colour. In the close-up photo, the brown speckling are clusters of zooxanthellae which the animal has got from the sea anemones it feed on. Another clue that it is from the family Aeolidiidae are the large white cnidosacs at the tip of each ceras. In this family the cnidosacs appear much loinger and often more slender than in other aeolids, where they are often more inflated and almost spherical in shape.

Best wishes,
Bill Rudman
