The octopus was out and active	Octopus bimaculatus, one of two SoCal 'two-spotted' octopus species. This one is usually subtidal and is larger than the one we normally see in the intertidal, O. bimaculoides.	Image Caption

Sheep crab (see cap for scale)	Sheep crab (Loxorhynchus grandis)	Hemisquilla ensigera (mantis shrimp or stomatopod) - see movie of a mantis shrimp's smashing appendage here and more on this particular species here
A mantis shrimp's 'apposition compound' eyes are highly unusual compared with other crustaceans, whom they diverged from hundreds of millions of years ago - see here	Constant twisting and turning allows the mantis shrimp to accurately judge the distance to any object in the field of view, provided it is not too far away.

Intertidal at Pt. Fermin, near Cabrillo Aquarium (low tide was at 17:20, after dark)	A limpet grazing on the featherboa kelp, Egregia menziesii. There are two limpet species that are hard to tell apart. One of them is Lottia insessa, a specialist feeder on E. menziesii. The second one, Lottia pelta, lives in a variety of microhabitats and it only resembles L. insessa when it is on or has recently been on this kelp.	Anthopleura sola
The territorial sequential hermaphroditic owl limpet, Lottia gigantea, the first mollusk to have its genome completely sequenced. There are also rough limpets, L. scabra, and acorn barnacles, Balanus gladula, on its back.	Class photo (missing Oscar)	Chestnut cowry (Cypraea spadicea)
