Though our nesting birds have left us, there was still lots to see in the intertidal last week.  HRAP interpreters stumbled onto some kind of sea slug party when they came across ten opalescent nudibranchs all gathered together on one rock-- and the next day they found even more.

On the north side of the Rock, interpreters spotted about a dozen healthy-looking sea stars, including several juveniles.

As for what the humans of Haystack Rock are up to, HRAP added a sustainable seafood display to the big red truck this week. Stop by for a chance to win a $50 gift certificate by answering a trivia question about sustainable seafood!

Creature Highlights
We've seen anemones take on a lot of ambitious meals here at Haystack Rock. Do you remember when we caught an anemone in the act of consuming a cormorant chick?



While some species of jellyfish are dried and eaten by people, most of us would probably shy away from the idea of ingesting a full, live (or recently alive) jellyfish. Not this intrepid Giant Green anemone (pictured here with a Lion's Mane jellyfish).
