Description

The length of the shell varies between 30 and 229 millimetres (1.2 and 9.0 in). It contains six to eight varices. These are singly spinous, the spines somewhat frondose, those on the shoulder of the whorls usually larger and curved. There are no interstitial ribs. The color of the shell is light yellowish brown, usually more or less pink-banded. The aperture is pink, with three or four darker bands.[4]

Distribution

This species occurs in the Red Sea and in the Atlantic Ocean off the Cape Verdes and the Canary Islands; and from Senegal to Angola. It has also been described as Murex turbinatus from the Mediterranean Sea.

gollark: I think that as long as teleportation was shown to be safe the ethical/philosophical issues would be outweighed by practicality pretty fast. I personally don't care about the continuity thing, however that's meant to work.
gollark: Not really the philosophy side, more "you can duplicate people" and "you can duplicate *things*".
gollark: They never consider the implications of that sort of replicator/teleporter technology.
gollark: Though I might be a bit worried about it since it *might* randomly disintegrate me or something if there's a bug in the reassembly bit.
gollark: If it's a very accurate reconstruction, I personally don't really mind.
