Sclerodoris apiculata from Reunion Island

March 24, 2007
From: Philibert Bidgrain

Dear Bill,
Reunion Island seaslugs

These specimens look like Sclerodoris apiculata with "the extensible papillae which are attached to the tips of scattered tubercles". In one of the photo we can see a pink spawn found under the same rock of the two specimens.

Locality: Etang Sale les Bains, Less 1 m, Reunion Island, Indian Ocean. Length: 30-40 mm. Photographer: Philibert Bidgrain.

Could it be their spawn?
What's your opinion about this identification?

Dear Philibert,
Yes this is S. apiculata, and I am pretty sure I found pinkish colour egg ribbons from animals in Tanzania, but I will need to check my notes. One problem with identifying this species is that the characteristic papillae retract back into the skin so in most preserved specimens there are no indications of them.

Best wishes,
Bill Rudman
