Dendrodoris elongata is aptly named, being a very long and slender nudibranch. It is not clear if all the animals shown on this page are in fact all the same species; all match some but not all aspects of the original description. All forms pictured below have been found at Kwajalein and Enewetak Atolls, and at least one has also been observed at Bikini Atoll. They are typically found by day under rocks, often under rocks that are partly buried in the sand, from the intertidal down to at least 15 meters. They move quickly away when exposed to light. Measured specimens have ranged in length up to 75mm. We also have D. elongata from Hawaii and the Solomons. Sometimes you'll see specimens without the white star-like dorsal blotches listed as Dendrodoris albobrunnea. However, examining just the photos below, it can be seen that those blotches vary from faint to distinct, on both whitish and brownish individuals. It seems more likely that they are all varieties of one species.
The next animal was photographed on a Kwajalein Atoll lagoon reef under a rock at a depth of about 6m on 26 May 2009.
The one below just deposited its egg mass.
The animal in the two photos below was found on 24 March 2014 with eggs under a large rock on the seaward reef.
