Far out! A very acrobatic jack knife clam, believe it’s Solen sicarius?, would love if someone could confirm that ID. Apparently these critters can literally jump inches in the air if they want to! First sighting of this type of clam for us - we’ve been seeing these razor clam type shells on the very deep end of our farm very occasionally, but then were on a long beach walk and saw this active little dude.
We referenced the classic, “Between Pacific Tides” to ID this clam. Ed Ricketts, the pioneering ecologist author, was hugely influential on John Steinbeck, both inspiring a character in “Cannery Row”, and later collaborating with Steinbeck for, “The Log From the Sea of Cortez”.
