Order: Nudibranchia

Genus: Reticulidia
Species: Reticulidia halgerda

Reticulidia halgerda is a phyllidiid nudibranch with a pale body covered in a network of raised white ridges and orange-tipped bumps. Its rhinophores are orange.

It feeds on sponges and, like other phyllidiids, defends itself with toxic chemicals rather than speed.

In the Philippines it is found on reefs and walls, often crawling openly on rock and sponges.
