Arctic Rock Borer Clam (Hiatella arctica)

Tidepool Tim says,  “The borer is a neat little clam!  They don't dig into the bottom - rather they just nest themselves in amidst rocks and stones and make a go of filter feeding there.  The most striking thing about this species is their bright red siphon tips - often it's the first thing you see when you encounter them.  We find them mainly in high current areas that deliver to them lots of good feed. Occasionally we will find them in the clutches of a sea star that is more than happy to pry their shell apart and feed on their bodies!”
