Description

Pharus legumen is up to 130mm long and has a characteristic bean-shaped shell. The shell colour ranges from white to light brown and it displays a light olive to yellow periostracum. The right valve has a single cardinal tooth and a short peg-like posterior lateral tooth, whereas the left valve has two elongated and closely spaced cardinal teeth and a single posterior lateral tooth.[4]

Distribution

Pharus legumen is commonly found in the English Channel, in the north-east Atlantic and in the Mediterranean Sea.[5]

Similar species

Pharus legumen is similar to other species of razor clam of the genus Ensis, Phaxas and Solen. The key feature to identify it is the presence of a ligament in the middle third of the shell.[4]

gollark: I use OpenSSH as a client and TinySSH as a server, it works okay.
gollark: What SSH client and server are you using?
gollark: Not weird key-exchange issues or whatever.
gollark: Weird. In my experience SSH either just doesn't work at all because I broke it somehow, denies me access for some reason, or works fine.
