The posterior end of the shell is, in contrast to the sand gaper, abruptly truncated. The shell may reach a length of 7 cm. The shell has a pale brown color while the siphon is colored olive or brown. Growth stages are usually clearly visible.
It is usually found on depths between 0 and 40 meters, buried in soft, sandy substrate. Only the siphons are visible, unless you dig it out.
The blunt gaper is widespread in the north Atlantic Ocean. It can be found anywhere along the coast of Norway.
