Distribution

This species was described from Angourie, northern New South Wales, Australia. It has been reported from Indonesia and the Red Sea.[3]

Description

Phyllodesmium crypticum uses camouflage and looks like the soft coral Xenia amongst which it is normally found. The length of the slug is 45–60 mm. This species contains zooxanthellae and has cerata which have a most distinctive shape. They are dorso-ventrally flattened and quadrangular in cross-section. A row of nodules runs up each of the four edges of the ceras and there are also scattered nodules on the two flat sides.[1]

Ecology

Phyllodesmium crypticum feeds on Xenia.[3]

gollark: Especially since I just realized another really bad one, "i.e." and such.
gollark: I checked nimble directory, but there don't *seem* to be things for this, but I was hoping someone might know where there is code for it because having to work out the edge cases myself would be bad.
gollark: I was thinking something like defining a sentence as having either an end-of-string or one of !?. at the end with a space after it.
gollark: I can probably come up with some sort of regex, but there would be annoying edge cases and stuff, so has anyone already *done* this and made a library?
gollark: What would the least terrible way to get the (English) sentence surrounding a position in a string?
