Hydrosaurus, commonly known as the sailfin dragons or sailfin lizards, is a genus in the family Agamidae.[1] These relatively large lizards are named after the sail-like structure on their tails. They are native to Indonesia (four species) and the Philippines (one species), where they are generally found near water, such as rivers and mangrove swamps.[2] Sailfin lizards are semiaquatic and able to run short distances across water using both their feet and tail for support, similar to the basilisks.[3] They are threatened by both habitat loss and overcollection for the wild-animal trade.[2]
In the 19th century, the genus was called Lophura, but in 1903, Poche pointed out that the name was preoccupied by a genus of pheasants.[4] Since Günther in 1873, the Sulawesi populations were considered to belong to H. amboinensis; Denzer et al. in 2020 resurrected H. celebensis and H. microlophus, increasing the number of species from three to five.[4]
They are the only members of the subfamily Hydrosaurinae.
Species
Currently, five species are valid according to the Reptile Database,[1][2][4]
