What’s in the Tidepools? – October 2023

A solitary sea anemone which has a cylindrical body with a centrally located mouth surrounded by tentacles. The body is soft and jelly-like, and it is green in color. The tentacles are thin and elongated, and they radiate out from the mouth in a circular pattern.

As tidepool season starts up again, October’s highlights included, sea hares, keyhole limpets, brooding anemones, ants and butterflies. Here is a sampling of what our volunteers observed during this month, and during the summer — thank you to everyone who contributed. Remember to send in your photos; we truly appreciate sharing them with everyone.

A Sea Lion decided to take over the rocky beach at the tidepool entrance one Saturday. Because he decided to take a nap on the beach, the tidepools access had to be closed. Volunteers kept watch over the Sea Lion.

Sea Hares and eggs are always fun to find in the tidepools.

Brooding Anemones were common this month.

VIP Sue found this Fragile Rainbow Star over the weekend.

  1. Hi Pam – While roving the Coastal trail yesterday morning I saw about 1000 birds flying in linear formations off the coast heading south. I figured they were migrating, not sure what kind of bird it was since I didn’t have binoculars (which I will not be without again!) Amazing! They were off shore by about 300-400 yards, at least past the breaks and flying low to the water. Appeared black and probable size of a cormorant. They just kept coming. Was very cool to watch. Too far off to get a picture.
