Goniodoridella sp. e241

This unidentified species is known in the Marshalls from four specimens found at Enewetak Atoll and several at Kwajalein. They all measured 2 to 6mm in length and under dead coral on lagoon reefs or pinnacles or in reef quarries at depths of 1to 10 meters. Like a number of other very small species, they are often overlooked, so they are probably more common than they seem. It closely resembles Goniodoridella sp. 1 in Gosliner et al (2008). The first two shots are of one of the Kwajalein specimens, found under a rock at a depth of 7m on a lagoon reef on 21 June 2009. This one was the largest, measuring 6mm in length.

This smaller specimen came from one of the Kwajalein reef quarries in July 2016. It has much shorter rhinophores than the one figured above, so initially we were unsure of the identification. However, we have noticed this species seems to be able to contract and stretch its rhinophores considerably.

Very small individual from August 2016.

Another medium sized individual.

The one below was one of the Enewetak specimens, photographed through a dissecting microscope.
