Trapania euryeia Gosliner & Fahey, 2008

This species of Trapania is brown with minute cream spots, on some specimens, and white patches. Notably is the white Y or V shape patch between the rhinophores and gill. It should be noted that the series of patches is quite symmetrical, right and left sides being identical.

This species is often confused with the temperate (cold water) southern Australian species, Trapania brunnea Rudman 1987. It is widespread in the Indo-Pacific, where it is found under coral rubble in less than 10 meters of water. Specimens may reach 10 mm in length.

A photo of Jim petting a shark in "Sleeping Shark Caves" off Isla Mujeres Island, Mexico, taken by Amy Foster his significant other, recently appeared in Dave Behrens' Diving Guide to Cozumel, Cancun & The Riviera Maja.

Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
