Description

The height of the shell attains 15 mm. The ovate-pyramidal shell is solid. The color of the shell is a uniform olive or a brownish-olive, belted with numerous reddish spiral bands. The shell is smooth except for faint growth lines above. The base of the shell scores by 5 or 6 narrow, spaced, concentric grooves that become stronger near the axis. The conic spire contains 6½ convex whorls. The body whorl is subangular at the periphery and convex beneath. The oblique aperture is brilliantly green inside, with a dusky submarginal band and a pale edge. The white columella is opaque and rounded. The umbilical region is imperforate or has a very minute perforation.[1]

This is the only species of Phasianotrochus outside Australia.

Distribution

This marine species occurs off Japan and Korea.

gollark: Spectre/Meltdown work using weirdness in speculative execution, which is where the CPU executes stuff faster by assuming one possibility is true then rolling it back if it's wrong.
gollark: CPUs have a bunch of privilege separation mechanisms, but flaws in them sometimes get around those.
gollark: The general thing with these flaws is just that the CPU behaves in some way it shouldn't/isn't documented as doing, so information is leaked from places or stuff which shouldn't be changed is changed.
gollark: Or static analysis of some sort, but detecting malware without just banning tons of legitimate code is extremely hard and possibly impossible.
gollark: Probably! Antiviruses aren't foolproof.
