I used to see Aplysias all over the beach (hundreds, rather than
dozens) at the Florida State University's Ball Marine Lab near
Carabelle (south of Tallahassee), apparently left there by a falling
tide. Their purple ink stained the beach and it looked rather like a
battlefield. I don't know for sure whether the animals survived the
subaerial exposure to the following tide, but my impression was that
every time I noticed them they were fresh. During the day they just
lay there immobilized under the influence of gravity. So they must
have crawled back down to the rocks underwater each time the tide came
up. I have wondered for years whether this might have been some sort
of a mating aggregation.
By the way; does anybody know what sea hares eat? Maybe algae?

Hi Debi,
No, but I have seen them under flat rocks with no apparent
entrance. I suppose they can squeeze through a small crack
or crevice. I have also found them (once) on the beach by
the dozens at low tide, crawling around on the rocks (at night,
of course). We hadn't had any particularly rough weather, so it
appeared that they got there intentionally. They were not there
the next night.
