Sohgenia palauensis Hamatani, 1991

Sohgenia palauensis is known in the Marshalls from several specimens at Enewetak and many from Kwajalein. It is reported on the Sea Slug Forum from Palau and Japan, including the Kerama Islands near Okinawa. The Marshall Islands specimens represent a considerable range extension eastward. The animals were found under rocks on shallow lagoon and seaward reefs and in reef quarries at depths of 1 to 8 meters. Seven measured specimens ranged in length from 5 to 9mm. The first three photos below show a specimen found on 4 July 2011 in a Halimeda patch on a Kwajalein Atoll lagoon slope in about 22m of water. We like the little fan-like structures at the ends of the dorsal cerata.

This animal was found on a Kwajalein Atoll lagoon reef on 22 June 2004.

The next two photos show an animal observed on a Kwajalein Atoll lagoon reef on 14 April 2008.

More from Kwajalein.

In a side view, the green from the body does not show up very well on this Enewetak specimen.
