Hi,

I observed this specimen of Tylodina perversa, during the long decompression stop at 9 m, after a technical deep dive in Saros Bay (NE Aegean Sea, Turkey).

Locality: Saros Bay, 9 m, Turkey, NE Aegean Sea, 27 April 2009, Inhabits yellow tube sponge. Length: ca. 20 mm longitudinal shell diameter. Photographer: Hakan Kabasakal.

Best regards,

Dear Hakan,

Thanks for this photo. I assume the sponge is Aplysina aerophoba, which is the preferred food of this species. In the close-up photo alongside we can clearly see the dark brown cap-shaped shell. Surrounding the dark brown is a broad band of pale yellow with dark brown radiating bands.  This is new shell material. It is much flatter than the older part of the shell and is yet to be covered with plant and animal growths.

Best wishes,
Bill Rudman
