Distribution

Widespread in the Indo-Pacific, from East Africa, including Madagascar and the Red Sea, to eastern Polynesia. North to southern Japan, Wake Island and Hawaii, and south to Australia.[2]

Habitat

This species lives in intertidal and sublittoral zones, to a depth of around 80 m.[2]

Feeding

Mitra mitra is known to be carnivorous, an active predator that feeds on smaller gastropods and bivalves.

Shell description

The maximum shell length for this species is 18 cm, usually to 14 cm.[2] Like in all Mitridae, the shell is elongate, somewhat fusiform, with a high spire. The aperture is elongate and narrow, and the outer lip is smooth and not lirate (grooved). Unlike other species of the genus Mitra, the spire is not strongly shouldered. The surface of the shell is smooth, with a few weak, spiral grooves towards the anterior end. The colour is white, with spiral rows of large irregular orange or red spots.

gollark: Then, I just gave up and compiled it on my other thing with an older kernel, where it eventually worked.
gollark: I decided to look at the code in more detail. This was a mistake. It contained thousands of lines with minimally useful comments, for some reason its own implementation of hash tables (this is very C, I suppose), and apparently its own implementation of WiFi mesh things even though that should really be handled generically for any device.
gollark: After I was able to work through git's terrible CLI enough to make that work, and "fixed" some merge conflicts, it somehow compiled still, but upon plugging in the thing, hung things again. I had dmesg open, and apparently it was a page fault somehow in the code assigning names or something?
gollark: Then I noticed that they had merged patches a lot from the repo for a similar wireless chip, so I decided to just try and merge the "kernel 5.10 compatibility" thing from that, which had not made it in yet.
gollark: There was a repo on GitHub for doing that with it, but `insmod`ing it after compiling *somehow* hung my kernel so I had to reboot.
