Periclimenes sagittifer[1] is a crustacean first described by Norman 1861. Periclimenes sagittifer included in the family Palaemonidae.[2][3] No subspecies listed in the Catalogue of Life.[2]

Description

A transparent body except for the typical violet arrow on the abdomen, the legs have coloring of yellow and blue alternately, and the tail is characterized by a blue arrow. Up to 25 mm [ citation needed ]. They live in symbiosis with sea anemones such snakelocks anemone (Anemonia sulcata), Aiptasia mutabilis, Cribrinopsis crass and Condylactis aurantiaca, feeding on the detritus.[4]

Distribution and habitat

Atlantic Ocean and the eastern Mediterranean Sea.

gollark: But that is... absolutely not the case.

gollark: I mean, yes, if you already trust everyone to act sensibly and without doing bad stuff, then privacy doesn't matter for those reasons.

gollark: Oh, and as an extension to the third thing, if you already have some sort of vast surveillance apparatus, even if you trust the government of *now*, a worse government could come along and use it later for... totalitarian things.

gollark: For example:- the average person probably does *some* sort of illegal/shameful/bad/whatever stuff, and if some organization has information on that it can use it against people it wants to discredit (basically, information leads to power, so information asymmetry leads to power asymmetry). This can happen if you decide to be an activist or something much later, even- having lots of data on you means you can be manipulated more easily (see, partly, targeted advertising, except that actually seems to mostly be poorly targeted)- having a government be more effective at detecting minor crimes (which reduced privacy could allow for) might *not* actually be a good thing, as some crimes (drug use, I guess?) are kind of stupid and at least somewhat tolerable because they *can't* be entirely enforced practically

gollark: No, it probably isn't your fault, it must have been dropped from my brain stack while I was writing the rest.
