Nile Valley Toad

The Nile Delta toad is a small species, with females growing to a snout-to-vent length of 38 mm (1.5 in) and males to 34 mm (1.3 in). The upper surface is a greenish-grey colour with dark blotches between the eyes, on the shoulders and hips, and usually a thin white stripe along the spine. The underparts are white, sometimes with dark specks, and the hips can have dark red patches. It has a long snout which is slender when viewed from the side, large distinct tympani (eardrums) and indistinct oval paratoid glands. The skin of the back is somewhat granular or may bear spiny warts, and that on the underside is slightly granular. The first finger of the hand is shorter than the second, most individuals have a red patch on the thigh, and males in breeding condition have an orange vocal sac. These and certain other characteristics distinguish this species from A. vittatus and from all other toads found in Egypt.

The Nile Delta toad was originally found in the Nile Delta in Egypt. It is a small, nocturnal aquatic species and is seldom seen, although its presence in an area may be known from the distinctive call made by the male. It occurs in swamps, rice fields and clumps of floating vegetation and has spread further upstream as reeds have become established along the margins of the River Nile and the canals associated with it. It is now present in Cairo and as far south as Luxor, where it is said to be abundant.
