The Other Sedna

While bumbling about looking for what few scraps of information exist about Sedna, I discovered a Sedna a little closer to home, in the form of a sea slug. And what do you know, but five short years ago, Glossodoris Sedna was Nudibranch of the Week.

"This species occurs throughout the length of the tropical eastern Pacific (i.e., Panamic) province, from Puerto Penasco in the northern Gulf of California, to the Islas Galapagos. It may be seasonally and regionally abundant or rare. In the summer at Puerto Penasco, it is one of the most abundant opisthobranchs; however this species is quite rare at Bahia de los Angeles. Glossodoris sedna has also been reported rarely in the Caribbean, from southern Florida and the Bahamas."

Several spectacular (and these things really are spectacular) nudibranch galleries can be found here, here, here, and here.
