Description

The length of the shell attains 5 mm, its diameter 1.75 mm.

The small oblong-fusiform shell is semi-pellucid. It is unicolorous white, or flecked with pale straw-colored spots. It contains six whorls of which three in the protoconch. These are closely and very finely cancellate. The subsequent whorls are slightly ventricose and almost smooth. The very delicate and irregular spiral striation across the whorls is almost evanescent. The body whorl is smooth centrally. The narrow aperture is oblong. The outer lip is nearly straight. It is incrassate, white and shining. The columella stands upright. The siphonal canal is short. The sinus is hardly expressed.[2]

Distribution

This marine species occurs in the Gulf of Oman

gollark: It's something like 8 characters, and does a clever thing to match any number (in unary) with factors other than 1 and itself. It also probably makes regex engines suffer horribly.
gollark: You can implement a primality checker quite easily with backreferences or something.
gollark: Probably not with strictly regular regular expressions, possibly with the extended ones everyone uses.
gollark: I'd say it's more that most mainstream languages use basically the same set of approved concepts.
gollark: Unfortunately, apparently no mainstream language is remotely aware of most useful language features which aren't just mildly extended C or OOP.
