Midwife toads (Alytes) are a genus of frogs in the Alytidae family (formerly Discoglossidae), and are found in most of Europe and northwestern Africa. Characteristic of these toad-like frogs is their parental care: the males carry a string of fertilised eggs on their back, hence the name "midwife". The female expels a strand of eggs, which the male fertilizes externally. He then wraps them around his legs to protect them from predators in the water. When they are ready to hatch, the male wades into shallow water, where he allows the tadpoles to leap out of their eggs. Five separate species of midwife toad are found across western Europe, northern Africa, and Majorca.

Midwife toads can be found in the snows of the Pyrenees, living at heights of 5,000–6,500 feet in areas such as the Néouvielle massif. Unlike the thin tongue of many amphibians, the midwife's tongue is round and flattened; its former family name, Discoglossidae, means "round tongue". In parts of France midwife toads live in sand dunes by the sea. They share this habitat with natterjack toads.

The Midwife Toad Egg Transfer

Five separate species of midwife toad are found across western Europe, northern Africa, and Majorca. Shy, nocturnal animals, they give away their presence by their ringing call. During the day, the midwife toad hides under stones and logs or in underground tunnels. It often hides in dry, sandy soil, which it finds easier to dig into using its forelegs and snout. It emerges at dusk to forage for food, but always returns to the same hiding places before dawn. During the winter, the common midwife toad hibernates in its hole or in a burrow that has been deserted by a small animal.

Food and feeding

The Midwife toad crawls around the area close to its hiding place at night to search for food. The toad uses the end of its long, sticky tongue to pick up prey, which includes beetles, crickets, flies, caterpillars, centipedes, ants and millipedes. Tadpoles feed on vegetable matter. They chew with tiny, hornyteeth. Young toads eat smaller sizes of the same prey that adults feed on. When the eggs are ready to hatch the male leaves them near the water.


The back of the midwife toad is covered with small warts. These warts give off a strong smelling poison when the toad is handled or attacked. The poison is so powerful that the toad has few enemies or predators. The poison also helps to keep the egg strings on the male's back safe from attack. The tadpole does not possess the poison, and therefore falls prey to fish and insects.

The Majorcan midwife toad has adapted to the harsh, dry conditions of this Spanish Island. it is found only in deep canyons in the northern mountains. Its body has evolved to become more flattened, which enables the toad to squeeze into narrow crevices in the rocks of its habitat. The only moisture available is in small, rain-filled puddles on ledges. Tadpoles are born and develop in these pools. Fossils of these species have also been found in Europe.

In laboratories

Apoptosis, the programmed cell death, was first observed in the developing of the tadpoles of the midwife toads 1842 by Carl Vogt.
