Dear Bill,
Reunion Island seaslugs

Alain Martinat took this photo in Rodrigues Island (near Mauritius). Before this photo I had never seen the spawn of this species except for Jeff Lockwood's photo (May 13, 2002). So do you think that this one is really a photo of Phyllidia varicosa spawn?

Locality: Rodrigues Island, Indian Ocean. Photographer: Alain Martinat.

Best regards

Dear Philibert,

Unless the photographer saw this animal laying the eggs we can't be 100% sure, but this type of egg ribbon with the ribbon attached flat on the substrate like this, rather than attached along one edge of the ribbon, is typical of the phyllidiids. It's hard to compare with Jeff's photo because we only have a view of the underside of a ribbon deposited on a smooth glass surface, but in both cases the ribbons seem to be unattached along the edges, so the ribbon in Alain Martinat's photo could well be that of P. varicosa.

Best wishes,
Bill Rudman
