It is then often noticed in groups. It has a pale body streaked with orange and a margin characterised by yellow-orange tipped fingerlike projections which resemble flames. The rhinophores are white and the gills are orange-striped.[5] EcologyThe fiery nudibranch is often found on bryozoans. Its egg mass is a sprawling white curl of several turns. {{Gallery|Fiery_okenia_amoenula_egg_ribbon.jpg|Two fiery nudibranchs with their egg ribbons }} References1. ^Rosenberg, G. (2015).
