Description

This species grows to a length of 35 centimetres (14 in) TL. The body is oval and laterally compressed and the scales are quite large. The eyes are large, as this fish is mainly nocturnal. The basic colour is pale pink, with deep blue to black scale margins. Median and caudal fins show a broad deep blue to black outer border. These fishes usually aggregate in small groups, often in mixed-species and mainly feed on plankton.

Distribution

Myripristis berndti is widespread in the Indian and Pacific Oceans.

Habitat

This nocturnal species can be found on tropical reefs hiding in caves or under ledges by day, at depths of from 1 to 25 metres (3.3 to 82.0 ft).

gollark: You can probably distinguish 4 colors at a decent distance, and switching twice a second seems vaguely plausible, so that's 4 bits a second.
gollark: Can you generate and detect different *colors*?
gollark: Assuming you can switch the light on and off pretty fast, and the magic can respond quickly, you might actually get decent data rates out of it.
gollark: Well, in that case I guess you could do automatic Morse code (or some variant), and if you could make a bright enough light (and maybe focus it on the receiving tower with mirrors or something), that might be longer-range than having to actually see the individual semaphore arms.
gollark: Oh, right. Hmm.
