San Juan Island's Original Sea Kayak Outfitters & Guides Since 1980

Sea Anemone

A low tide in the San Juan Islands can seem like a journey into another world, as the exposed intertidal zone reveals its’ inhabitants.  Our seasea kayak san juans friday harbor kayaking tours often are timed perfectly for some serious tide-pooling.  One of the predatory denizens we encounter is the Green Sea Anemone.  This stationary polyp displays filtering tentacles that sift food particles from the sea but also have stinging nematocyst tentacles that emit toxins that paralyze small fish and shrimp.  When exposed to the air at low tide, these tentacles retract.  Eye-popping colors and Dr. Zeuss shapes make for exceptional and surreal viewing of the intertidal zones of the San Juan Islands. and sea kayaking takes us to remote beaches where these creatures can be found.
