Navanax aenigmaticus from Colombia.

From: Phanor Montoya

This Cephalaspid is Navanax aenigmaticus I'm sure of that! Found on a shallow rocky area under a rock (Santa Marta, Colombia).
Length 1.5-2 cm.

Dear Phanor,
Yes, this is indeed N. aenigmaticus. Although this species was originally described from the Pacific Coast of central America, Terry Gosliner (1980) could find no morphological reasons to separate specimens from the Caribbean.

I've tried to show the characteristic blue spots along the parapodial edge (arrows) but although I can see them clearly in your original image file, I'm afraid they disappear when I put the photo on the web.
Best wishes,
Bill Rudman.
