I took this photo at Tulamben, Bali, Indonesia in 2007. This nudi was approx 10 mm in length and was found in less than 5 m depth. Sorry the quality of the photo isn't fantastic
Locality: Tulamben, <5m, Bali, Indonesia, Easter, 2007, volcanic sands. Length: 10mm. Photographer: Peter Eyre.
This is Phestilla minor, a small aeolid which lives on and feeds on species of the coral Porites. If you look at the species Fact Sheet you will see links to information on species that feed on coral. The little sausage-shaped packages in your photo are egg masses laid by the Phestilla. It has a remarkably brief egg and larval stage, and once settled out of the plankton, baby slugs can be laying eggs within a week.
