Aplysiopsis oliviae from British Columbia

Hi Bill,

Here is Aplysiopsis oliviae. It is not a nudibranch, but a sacoglossid opisthobranch, from the Hermaeidae family.  This is a very rare animal known formerly from Monterey Bay, California to the southern Gulf Islands, British Columbia.  I found it in 1998, 450 miles further north, at Seymour Inlet on a muck dive at 20 feet on a piece of kelp.  Whether it could be attributed to El nino or just that few people look for creatures this tiny is the question, I suppose!

The Forum is running much faster, by the way.

Thanks Marli,
This is one of the few sacoglossans which aren't predominantly green! I see that Dave Behrens could not find a photo for Pacific Coast Nudibranchs [1980 - Edition 1] so this may be one of the few published photos of the animal.

I'm glad you are finding the Forum running a lot faster. I hope everyone can notice a significant difference. Apart from a shutdown, beyond our control on Saturday, everything is running well and hopefully much faster.

Best wishes,
Bill Rudman.
