Berthellina citrina from southern New South Wales

From: Dave Harasti


Bill,

I'm having trouble identifying this species. Photo's were taken in Jervis Bay [southern New South Wales, Australia] in about 3 metres of water with water temp about 22 degrees. It was also during a night dive and it looked like it was feeding as it was moving pretty quick!

Cheers,
Dave Harasti

Dear Dave,
This is a 'side-gilled' slug or pleurobranch called Berthellina citrina. B. citrina feeds on sponges, corals and possibly other colonial animals, so it doesn't need to move fast to catch its prey. It does tend to live in shaded places and in shallow water is usually found under rocks during daylight, being more active at night. Perhaps your animals were moving away from your light.

Best wishes,
Bill Rudman.
