This small Janolus has rarely been found on the Kwajalein Atoll seaward reef, and has also been found at Rongelap and Majuro. The first few photos below show a Kwajalein specimen at a depth of about 16m on the wall of a small cave at night on 12 November 2016.
The Rongelap specimen photographed by Ken Cone.
A Majuro specimen from John and Lynette Flynn had unusual coloration, in particular partly black rhinophores and brown tips to the dorsal processes.
Another from Majuro from Ken Cone and Beth Van Zummeren is below.
The first specimen was found at Kwajalein Atoll under a rock on a Kwajalein Atoll seaward reef at a depth of 6m on 22 February 2010. It measured just 6mm. The photos below were taken with a low depth-of-field digital microscope and are not sharp, but they show the overall structure of the animal, with its characteristic mid-body stretch bare of processes.
