Tenellia sp. e293

While somewhat similar to some forms of Cuthona yamasui on the Sea Slug Forum, this appears to be something different. It was long known from the Marshalls from three specimens, one from Enewetak and two from Kwajalein. The Enewetak specimen crawled out of an algae sample collected from the Medren Pier pilings. Both Kwajalein specimens were found at night in ledges at depths of about 15 meters, one on a lagoon pinnacle and the other on the leeward seaward reef. The Enewetak specimen measured 12mm in length. This is figured in Gosliner et al (2008) as Cuthona sp. 27. In the summer of 2016, Jay Lord and Stan Jazwinski observed numerous individuals exposed at night in the shallow spur and groove system on the oceanside of Kwajalein Atoll's east reef.

The 9mm specimen below was found at a depth of 6m on a Kwajalein lagoon pinnacle under a rock on hydroids on 30 August 2010.

This photo by Jay Lord shows one of the specimens exposed at night in the shallow spur and groove system on the oceanside of Kwajalein Atoll's east reef.
