Leiopelma hamiltoni (brown New Zealand frog; Stephen Island Frog)

Wikipedia Abstract

Hamilton's frog (Leiopelma hamiltoni) is a primitive frog native to New Zealand, one of only four extant species belonging to the taxonomic family Leiopelmatidae. The male remains with the eggs to protect them and allows the tadpoles to climb onto his back where they are kept moist. It is named after Harold Hamilton. The holotype is in the collection of the Museum of New Zealand Te Papa Tongarewa.

EDGE Analysis

This species is one of the rarest and most ancient frogs in the world. It was originally found on both the North and South Island of New Zealand, but its range was reduced to a 600 m sq. boulder bank near the summit of Stephens Island. It is a ground-dwelling and night-active species that hides in damp, mossy rock crevices during the day. Males guard the nesting site and carry the newly hatched young on their backs. Despite being less than 50 mm long, it is New Zealand’s largest native frog. It is threatened by its tiny range and small population, introduced and native predators, and potentially a virulent fungal disease (chytridiomycosis).
