Hypselodoris cantabrica and parasite

September 8, 2007
From: Joao Pedro Silva

Dear Bill,

Yesterday I had the most productive dive ever. At least 10 species of nudibranchs were observed plus the more commonly found Aplysia fasciata and Aplysia punctata.

Locality: Peniche, 10 metres, Portugal, North Atlantic, 02 September 2007, Rocky bottom. Length: 3cm. Photographer: Joao Pedro Silva.

While looking at the photo of a pair of large Hypselodoris cantabrica mating I saw two small copepod parasites, one on the gills and the other next to the genital opening of the individual on the right. This was the first time I noticed these small creatures and I'm considering reviewing all of my previous photos (ok, most of them) to see if there are more parasites around.

Cheers,
Joao Pedro Tojal Loia Soares Silva

Thanks Joao Pedro,

The paired egg sacs of these little copepods certainly stand out.

Best wishes,
