This mollusc is a suspension feeder and can burrow with great rapidity to escape predators.

The valves of the rosy razor clam are relatively small, thin and finely sculptured.

Many clams are detritivores, consuming decomposing organic matter they find in their environment, but this clam is a filter feeder, drawing water in through one siphon, removing the edible particles and exhaling the water through the other siphon.

[4] In an apparent attempt to distract predators, the tips of the two siphons can be shed, and these pulsate as they drift in the water column.
