Crocodylus raninus — Ross, 1990
Crocodylus raninus, the Borneo crocodile, is an enigmatic species of freshwatercrocodileendemic to the Southeast Asian island of Borneo.[2] Its taxonomic status is controversial and unclear: it has been considered by some authors as a synonym of Crocodylus porosus, although a redescription in 1990 and 1992 presented evidence of distinct identity.[3][4] Currently, it is considered to have been misidentified C. porosus or C. siamensis.
