Leiopelma archeyi (Archey's Frog)

Wikipedia Abstract

Archey's frog, Leiopelma archeyi, is an archaic, rare frog native to New Zealand, one of only three (or four) extant species belonging to the taxonomic family Leiopelmatidae. It is named after Sir Gilbert Archey, the former Director of the Auckland Institute. The holotype is held at the Auckland War Memorial Museum. It is found only in the Coromandel Peninsula and near Te Kuiti in the North Island of New Zealand. This species, along with others in the family, have changed little over the past 200 million years, and thus represent "living fossils".

EDGE Analysis

Archey’s frog is almost indistinguishable from the fossilised remains of frogs that lived 150 million years ago, leading to its description as a “living fossil”. One of the world’s most primitive frogs, it has bizarre features such as tail-wagging muscles (despite having no tail to wag) and no eardrums. It therefore does not communicate by sound, but is instead thought to employ scent. The male guards the eggs in moist nests and the tailed froglets that hatch out crawl onto the father’s back where they remain for several weeks whilst they develop. It is primarily threatened by a virulent fungal disease (chytridiomycosis), as well as introduced predators such as rats and mice.
