Description

Felimare lajensis is dark blue in colour with a series of yellow longitudinal lines. The edge of the mantle is white and there is a series of darker blue spots on a blue background between the border and the first of the yellow lines. The rhinophores are entirely blue and the gills are also blue with very dark blue rachises. The maximum recorded body length is 30 mm.[4]

Habitat

Minimum recorded depth is 7.3 m.[4] Maximum recorded depth is 25 m.[4]

Feeding habits

This species feeds on a blue species of sponge, Dysidea etheria.[5]

gollark: Use Arch Linux, the superior Linux.
gollark: Isn't the market for high-powered VPSes/servers quite saturated at this point?
gollark: Even with computers they still managed to mess the phone network up so horribly.- calls appear to use an awful voice codec- multimedia messages are overcharged massively for- caller ID spoofing is a very common thing- mobile phones have stupidly complex modem chips with excessive access to the rest of their phone, closed source firmware and probably security bugs- SIM cards are self contained devices with lots of software in *Java*?! In a sane system they would need to store something like four values.- "eSIM" things are just reprogrammable soldered SIM cards because apparently nobody thought of doing it in software?!- phone towers are routinely spoofed by law enforcement for no good reason and apparently nobody is stopping this- phone calls/texts are not end to end encrypted, which is practical *now* if not when much of the development of mobile phones and whatever was happening- there are apparently a bunch of exploits in the protocols linking phone networks, like SS7
gollark: I think if a tick takes a few seconds or something.
