Northern Spadefoot

Notaden melanoscaphus

A medium-sized (to 5 cm) round burrowing frog. The head and mouth are small, limbs are short and the skin has a rough texture. The fingers are long and the rear feet have a sharp black shovel-shaped inner metatarsal tubercle. Very dark brown colouration with paired black patches on the head and back, sometimes bordered with red.

Breeding

Breeds in temporarily flooded areas of clay or sandy soils.

Call

A loud 'whoop...whoop...whoop'.

Eggs

The spawn is a large shapeless clump of over 1000 eggs.

Tadpoles

Not much known. Tadpoles have 3 upper and lower tooth rows.

Other Notes

The specific name melanoscaphus refers to the black colouration of the inner metatarsal tubercle on the foot. This characteristic distinguishes it from the desert spadefoot (Notaden nichollsi) that occurs further to the west and south. Like all the Notadens, they ooze a creamy sticky liquid when handled or threatened.
