#Nudibranch superpowers! I'm updating the blog on my website with tidepool meanderings, starting with nudibranchs. Here is my Monterey #tidepool favorite, Hopkin's Rose. It uptakes its color from its prey, Rosy Bryozoan.

Low-tide at #GreatTidePool. #Ricketts and #Steinbeck were right about the richness of #invertebrates here! Lots today starting with a flat crab, a two-spot #octopus, brooding anemone and 4 #nudibranchs.

A day for chitons on low tides near Ed Rickett’s Great Tide Pool in Pacific Grove. Here's a huge gumboot chiton chillin' with a bat star and lined and mossy chitons below.

For Invertefest day 1 and celebrating King Tides is my 5 Phylum intertidal cave. How many different Invert groups can you find from this Monterey tidepool cave?
