Grand Cayman Nudibranchs ?

September 1, 2006
From: Brian Mayes

Hi Bill,

I hope you can't help with identification of these critters, which I presume to be nudibranchs. I found the two in what could be a mating position, on Neptune's Reef, Grand Cayman

Locality: Island, 10 to 15 metres, Grand Cayman, Carribean, 8 November 2005, Reef. Length: 2 to 3 inches. Photographer: Brian Mayes.

Best Regards

Dear Brian,
I am pretty sure these are not nudibranchs but some strange holothurian or sea cucumber. The one on the right seems to have a flattened base and does look a bit like a slug, But the flattened side is covered in small 'legs' which I guess are modified tube feet. The one on the left of your photo has a more typical cylindrical 'cucumber' shape and seems to have a ring of feeding tentacles [gills] at the end nearest the bottom of the photo.

Best wishes,
Bill Rudman
