Nesoryzomys indefessus (Thomas)

Santa Cruz Rice Rat (Nesoryzomys indefessus)  

The Santa Cruz Rice Rat was described in 1899, it was restricted to the Isla Santa Cruz, Galápagos Islands.

The species disappeared soon after its description due to the introduction of Black Rats (Rattus rattus (L.)) and feral cats.


The Fernandina Rice Rat (Nesorhyzomys narboroughi Heller), one of only four Galápagos Islands rice rat species surviving until today, was formerly treated as a subspecies of the Santa Cruz Rice Rat.
