Roboastra tentaculata is a species of sea slug, a polycerid nudibranch, a marine gastropod mollusc in the family Polyceridae.[2]
This species was described from Guam.[1]
Tentaculata is used to describe Roboastra tentaculata due to the presence of oral tentacles.[3] Oral tentacles allow sea slugs to move and obtain information from the environment.[4]
In order for phylogenetic integrity, Roboastra tentaculata was moved into Roboastra from the genus Tambja.[5][6]
The bulk of the sea slug body is green, along with bright yellow or orange stripes outlined with brown.[3][7] Two green rhinophores with lamellae and rhinophoral cases are noticeable.[3] This sea slug has green gills of two different sizes.[3] Bright green oral tentacles are also found on the back of the organism, opposite of a straight green foot located on the bottom.[3] Also present is a radula with smooth and large teeth.[3] The digestive system is composed of salivary glands, an esophagus and an oral tube.[3] R. tentaculata also have three reproductive duct structures; a hermaphroditic, vaginal and uterine duct.[3] The first duct is hermaphroditic with an ampulla, vas deferens and a spiked penis.[3] The second tract is composed of a small vaginal tube and a bursa copulatrix.[3] The third duct contains a uterine tube and one oviduct.[3]
