Description

Saw about 30 California seahares washed up on the beach. Some were blackened and dead, others were brown, purple and one was a beautiful greenish blue. We were walking during a very low tide.

Thanks Ken-ichi for the lead on this cool gathering. LOTS of mating in shallow waters. Hadn't seen these since Scuba days in Monterey Bay.

Description

Hundreds of these in Lake Merritt right now. Well, at least 100, could be more. We only checked the area around the channel but there were plenty in the channel and in the lake around the channel. Many seemed to be eating the Ulva, others seemed to be forming big clusters like the second pic. Is that mating behavior, and are those eggs in the middle? We drew a small crowd of onlookers, so we did some 'splainin'. None of them inked us. The slugs, not the onlookers.

Thanks to Joel Peter for the lead.
