Alytes obstetricans (Olive midwife toad)

Wikipedia Abstract

The common midwife toad, Alytes obstetricans, is a species of midwife frog in the family Alytidae (formerly Discoglossidae).It is found in Belgium, France, Germany, Luxembourg, the Netherlands, Portugal, Spain, Switzerland, and the United Kingdom (although, in the latter, only as an introduction). Like other members of its genus (Alytes), the male toad carries the eggs around entwined on his back and thighs until they are ready to hatch.

EDGE Analysis

The common midwife toad is in fact a warty frog, and spends most of its time on land. Its warts produce a potent poison to protect itself from would-be predators, and it is nocturnal and lives in burrows to avoid drying out. It is named after its unusual breeding behaviour, in which the males carry strings of eggs wrapped around their hind legs for several weeks, keeping them moist until ready to hatch. Midwife toads began to evolve independently of all other modern day species about five million years before birds appear in the fossil record. The common midwife toad has a wide range in Europe but, like so many other amphibian species, has suffered population extinctions at the hands of the devastating chytrid fungus.
