Description

Shells of Opeatostoma pseudodon can reach a length of about 29–75 millimetres (1.1–3.0 in).[3] The shells are white or brown with thin brown or black stripes. The body of the snail is reddish. This species has the longest apertural tooth developed by any gastropod. By means of this long spine or thorn (hence the common name) which grows from the tip of the snail's aperture, they anchor themselves in the sandy and coral rubble substrate.[6]

Behavior

These snails live under rocks, usually partially buried in coral sand. They are active nocturnally. They mainly feed on small worms[6] and on other gastropods.[7]

gollark: Well, if they don't move it's fine, but the IDs were removed some time back.
gollark: If you want to do something actually usefulish, "FORTRESS", you can trilaterate GPS pings and find anyone who sends them (but not actually uniquely identify them since a few versions back).
gollark: If you have a hidden piston door or something and wireless control I guess it makes sense?
gollark: There are valid reasons to spam arbitrary channels, like when someone had a wireless light controller which worked by just checking channel and reply channel, and I knew *approximately* what those were, and wanted to meddle with their lights. But doing it without a target in mind is just pointless.
