Himantura fava
Descrizione della specie da Wikipedia in inglese descrizione completa
Taxonomy The first known specimens of this species were two 130 cm (4.3 ft) wide adult females collected near Orissa, India by the steamer Golden Crown, and described by Scottish zoologist Nelson Annandale in a 1909 issue of Memoirs of the Indian Museum. He remarked that it was closely allied to Himantura uarnak with the main distinguishing feature being the mouth. Smaller differences included a yellow, as opposed to white, reticulated pattern on the dorsal surface, and the lack of stellate denticles. The species has had a confused taxonomic history. Many sources still consider H. fava to be a synonym of Himantura undulata.
Description This species is characterized by absence of skin fold on the ventral surface of the tail, in common with other Himantura species. The main body disc is somewhat quadrangular.
