Bibliographic data :
Phestilla sp. 1 could be confused with Phestilla lugubris but in Phestilla lugubris the ceratal surface bears numerous, low, irregular nodules and white patches.
The cerata are long and cylindrical with a rounded tip. The ceratal surface is regularly pleated. Sometimes the tip is white and separated by a darker ring from the rest of the ceras.
The oral tentacles are broad, relatively short, and their tips are pointed.
Phestilla sp. 1 lives and feeds on species of the scleractinian coral genus Goniopora (family Poritidae).
The spawn consists of numerous, creamish, cup-shaped spirals attached to the host coral by their narrow end.
