Platymantis megabotoniviti Worthy, 2001

Viti Levu giant ground frog (proposed)

 

 

Taxonomy & Nomenclature

 

 

Conservation Status

Last record: Holocene

 

The Viti Levu Giant ground frog was much longer, but also stouter, than either of the two living Platymantis species which inhabit Fiji, suggesting it had a predominantly terrestrial lifestyle. It would therefore have been much easy prey for the Rattus exulans and R. praetor which were introduced by Melanesians some 3,000 years ago, as compared with the two living Platymantis sp. And although no unequivocal evidence of a Rattus-induced extinction of P. megabotoniviti has been produced, this is probably the cause of its extinction on account of a seeming lack of any other possible cause.
