Batangas Nudibranch

Halgerda batangas


This species of nudibranch has a white translucent body covered by orange-tipped pustules. In between the pustules on the mantle are fine intersecting red-orange lines. The rhinophores and gills are white with black speckles.


Found singly or in pairs on coral and rocky reefs among sand and rubble; widespread in the tropical West Pacific.


This is my first H. batangas in Davao Gulf (although I've spotted this in other areas before). It was inside a crevice in about 12m of water at Limao Reef, off the western coast of Samal Island, Philippines. The nudiranch measured about 3cm long.
