Description

Adults are up to 65 millimetres (2.6 in) long, with a carapace 32 mm (1.3 in) long; the body is chestnut brown with a green tinge, and the spines projecting from the carapace are red at the tips.[3] The rostrum is triangular in shape with four spines on either side.[4] The first pair of pereiopods are 1½ times as long as the body, and have well-developed claws.[4]

Distribution and ecology

G. squamifera is found from Norway to the Azores and in the Mediterranean Sea,[3] and is the most commonly found species of squat lobster on the shores of Northern Europe.[4] It lives between the low water mark and depths of about 70 metres (230 ft),[3] under stones and in rock fissures.[4]

G. squamifera is chiefly nocturnal,[5] and catches passing prey, such as small fish, with its claws. Species which feed on G. squamifera include the fishes Scorpaena porcus and Serranus atricauda.[6]

gollark: I'm not entirely sure what the aim is - maybe they originally wanted to go for highly concurrent systems or something, but nowadays it seems to mostly be used in trendy cloudy things, servers, command line utilities, that sort of thing.
gollark: I think my use cases are nice usecases, and I think it has flaws even in the domains it seems to be targeted at.
gollark: I think it should at least not, essentially, deliberately cripple itself at some classes of thing.
gollark: I'm not sure exactly what they're targeting - maybe trendy cloud™-type tools, simple webservers, etc - but even *in* that domain it just seems bad to me.
gollark: If they did in fact mean it as a DSL for deploying bees against Google Cloud, they should say so.
