Distribution

This species was described from Luzon Island, Philippines. It has also been reported from Timor, Sulawesi and Moreton Island, Queensland, Australia.[2]

Description

This Okenia has a broad body and five or six pairs of long, pointed, lateral papillae. There are four to seven papillae on the back, in front of the gills. The body is translucent white and there are broken chocolate brown bands which run from between the rhinophores to the tail, encircling the back and gills. There are additional chocolate brown spots in the middle of the back and on the sides of the foot.

Ecology

The diet of this species is a ctenostome bryozoan.[2]

gollark: I mean, JSON has problems, but it is at least simple and coherent.
gollark: Maybe? Less so for some.
gollark: I was looking at the WHATWG's documentation on application/x-www-form-urlencoded and it says this:> The application/x-www-form-urlencoded format is in many ways an aberrant monstrosity, the result of many years of implementation accidents and compromises leading to a set of requirements necessary for interoperability, but in no way representing good design practices.
gollark: I feel like they could probably just, if it's for array literals, get away with limiting it to 16 or so with no major issues.
gollark: It's allegedly to make neater bytecode.
