Corvan Gilvos are small non-sapient arboreal organisms native to the rainforests of planet Corvan II. Though they have no clearly visible head, they do have several jointed appendages on the frontal part of their body. The fact that its body is shaped like a tree branch renders this creature with an excellent camouflage in its natural environment, making it difficult to be spotted by predators. Nevertheless, as of 2368, the Corvan Gilvo is in serious risk of extinction due to its habitat being threatened by industrial pollutants, which resulted in only 14 known remaining specimens. That same year, the USS-Enterprise D transported two of them in order to introduce the species to planet Brentalia.
