A brooding seastar member of the Leptasterias aequilis species complex, with several recently
released tiny juveniles just to the right of mom's arms. Like her, they have six arms. Click on the thumbnail image to see a larger version, and you can zoom in to see more details.
I temporarily removed her from the brood (see next two images), but she seemed to
resume her brooding when she was returned to her former position.

A polychaete known as a scale worm (Polynoidae) because it has overlapping scale-like disks called elytra
on its dorsal side. These are free living predators but often can be found living as commensals on the undersides of seastars,
keyhole limpets, gumboot chitons, or other animals.

Tegula brunnea (brown turban snails) are found in the low intertidal but are probably more common in the
shallow subtidal. This one was found feeding on a drift kelp stipe.

This limpet-shaped snail of the family, Hipponicidae (Littorinimorpha), Hipponix tumens, lives a
sedentary life with a thin second shell attached to the rock under where it lives. They feed on detritus with an out-stretched proboscis.

I saw four wild turkeys together crossing the road as I was leaving the Reserve, almost to PCH.
