Common midwife toad

In this little toad family, the dad looks after the eggs. He carries them wrapped around his back legs!

The common midwife toad is a small toad of western Europe. It is famous for the way it cares for its eggs: after mating on land, the father wraps the strings of eggs around his back legs and carries them for weeks, until they are ready to hatch. Then he takes them to the water. Its call sounds like a tiny bell.

Alytes obstetricans (family Alytidae) is a small terrestrial toad of western Europe, from northern Iberia through France to Belgium, Luxembourg, Germany, Switzerland and the southeastern Netherlands, with an introduced population in Great Britain. Males carry the egg strings on their hind legs until hatching. Its IUCN assessment (Salvador et al.; Global and Europe; assessed 20 February 2023, published 2024) lists it as Least Concern but decreasing.

Meet the common midwife toad

This toad is small and plump.

It has big eyes.

Its skin is brown or gray with tiny bumps.

The common midwife toad is a small, stocky toad that grows up to about 5.5 centimeters long. It has big eyes with pupils shaped like upright slits, and its eardrum is clearly visible.

Its back is brown, gray or olive, dotted with small red to yellowish warts, and its belly is whitish. The upright slit pupils help tell it apart from young common toads.

RAVON (Netherlands): a small, compact toad up to 5.5 cm; large eyes with vertical pupils; clearly visible tympanum; ground colour brown, grey or olive with small red to yellowish warts; whitish belly. BfN (Germany): the vertical slit-shaped pupils distinguish it from young common toads. The IUCN uses a restricted concept of the species after Alytes almogavarii, formerly a subspecies, was split off (Dufresnes and Martínez-Solano 2020).

Sunny slopes, stones and ponds

This toad lives in western Europe.

It likes sunny, stony places near ponds.

Common midwife toads live from the northern half of Spain and Portugal, through most of France, to Belgium, Luxembourg, western Germany, Switzerland and the far southeast of the Netherlands. They live from sea level up to 2,400 meters in the Pyrenees mountains.

They live on land in many kinds of places: forests, stony slopes with few plants, walls, embankments, quarries and gravel pits, farmland and even towns. In Germany they like warm, sunny spots with little plant cover. They need damp hiding places nearby, such as cracks in rock or soft soil they can dig into.

IUCN: northern Portugal and Spain (subpopulations very fragmented), most of France, southern Belgium, extreme southeastern Netherlands, Luxembourg, western and north-central Germany, western and northern Switzerland; 0 to 2,400 m (Pyrenees); EOO 1,056,482 km² (Maiorano et al. 2013); terrestrial habitats incl. temperate forest, semi-arid areas, walls, embankments and stony, sparsely vegetated slopes, traditional farmland and urban areas; introduced to the UK with at least one established subpopulation. BfN: originally the open floodplains of upland rivers; in Germany now mainly sunny, warm, sparsely vegetated sites such as clay, sand and gravel pits and railway embankments, with damp crevices or diggable soil. RAVON: in the Netherlands naturally only in South Limburg.

Sightings recorded · Records of wild sightings (GBIF)

Counts of GBIF records of wild observations (human and machine) and preserved specimens. Records include introduced populations, vagrants, escaped or released animals and misidentifications, so a country with records is not necessarily part of the native range.

Wild sightings have been recorded in France, Switzerland, Spain, Netherlands, Germany, Portugal, Luxembourg, Belgium and 6 more places.

Range maps show where scientists say an animal lives, often country by country. An animal may live in only part of a country shown, and sightings records can include animals that wandered far from home.

Moths, worms and beetles

This toad eats bugs, worms and snails.

Midwife toads hunt small animals without backbones: moths, earthworms, snails, ants, beetles and others. They are most active in the evening, soon after sunset.

Their tadpoles grow up in all sorts of water, from puddles in wheel ruts and small pools to ponds and bigger lakes, but not in fast streams or in water with many fish. The tadpoles probably eat both tiny bits of plants and tiny animals.

RAVON: diet of moths, earthworms, snails, ants, beetles and other invertebrates; larvae probably take both animal and plant material; most active shortly after sunset. BfN: larvae use sunny to half-shaded waters of every size, from temporary wheel ruts and small pools to ponds and larger still waters, but avoid fast-flowing and very acidic water, and high fish densities prevent colonisation. The IUCN assessment gives no diet details.

Did you know?

Mom toads can call too.

Not only male midwife toads call: the females can call too.

Both males and females call (BfN; RAVON).

A dad with eggs on his legs

After mating, the dad wraps the eggs around his back legs.

He carries them everywhere he goes!

Midwife toads mate on land, not in water. As the female lays her strings of eggs, the male wraps them around his back legs. He then carries them for about three to seven weeks, keeping them damp, and wets them with water when he needs to.

The eggs start out whitish yellow and turn bright yellow or brown as the young inside grow. A male carrying eggs is easy to recognize.

Mating takes place on land; the male winds the female's egg strings around his hind legs (BfN; RAVON). He carries them for three to seven weeks (RAVON), or 15 to 50 days depending on temperature, moistening them with water when necessary (BfN). Eggs are whitish yellow at first, later bright yellow or brown (RAVON). A male with an egg mass wrapped around its hind legs is an unmistakable identification mark (BfN).

How big is it?

Length: up to 0.06 m (grows up to 5.5 cm long (RAVON, Netherlands))

From the father's legs to the pond

When the eggs are ready, the dad goes to the water.

The tadpoles hatch and swim away.

Just before the eggs hatch, the father goes to a pond or pool and lets the tadpoles out into the water. Because he protects the eggs, few are eaten, and the tadpoles start out bigger and more developed than those of frogs and toads that lay their eggs in water.

Tadpoles usually turn into toadlets in 9 to 12 weeks. Late ones, or those in cold water, spend the winter in the water and change the next year, when they can be 6 to 8 centimeters long.

Just before hatching the male seeks a suitable water body and releases the larvae; he then starts calling again and can usually mate again several times in a season, and females can lay several times per season (BfN; RAVON). Low egg losses to predators give high hatching rates, and larvae are larger and more developed than those of pond-spawning species (BfN). Metamorphosis after 9 to 12 weeks, depending on weather, hatching date and food; late or cold-water larvae overwinter and metamorphose the next year at total lengths of 60 to 80, rarely 90 mm (BfN). The IUCN notes larvae frequently hibernate. Sexual maturity after about 2 to 3 years; probably able to live 8 years or more (Günther and Scheidt 1996, via BfN).

A life, step by step

A call like a little bell

This toad's call sounds like a tiny bell.

Moms and dads can both call.

Midwife toads call with a short, clear, whistling note, most of all in the evening and at night. From far away, a group of calling toads sounds like little bells ringing, and one of its German names means 'bell frog'. Females can call as well as males.

In the Netherlands, calls can be heard from late March or April until August. They hide in damp cracks in rock, in tunnels or in soft soil they can dig into.

BfN: a bright call reminiscent of a small glass bell, mostly in the evening and at night in the breeding season, produced by both males and females; from a distance a calling group sounds like bells, hence the German name 'Glockenfrosch'. RAVON: a short, melodious, whistling call, heard from late March or early April to August in the Netherlands, mostly in the evening and at night but also on warm days; overwintering recorded in limestone quarries, lime kilns and buildings. BfN: needs damp shelters such as fissures, crevices or tunnels in rock or diggable soil.

Did you know?

The toad dad carries the eggs on his legs!

A male midwife toad wraps the strings of eggs around his back legs and carries them for weeks, until the tadpoles are ready to hatch.

Paternal egg-carrying on the hind legs for 3 to 7 weeks (RAVON) or 15 to 50 days (BfN).

Losing breeding ponds

Some of the ponds where these toads breed are gone.

People protect the toads and their homes.

The common midwife toad is listed as Least Concern because it lives over a wide area and is still common in many places, such as much of France. But its numbers are going down. Farming has destroyed some of its homes and breeding ponds, a fungus disease called chytrid has made it disappear from some places in Spain, and fish brought into ponds from elsewhere eat it.

It is protected by European law, and Germany's national Red List (2020) lists it as strongly endangered.

Least Concern (Salvador et al.; Global and Europe; assessed 20 February 2023, published 2024; trend decreasing; also LC for the EU 27). Threats: habitat loss mainly from agricultural development, including breeding sites; fragmentation in Spain and Portugal; chytridiomycosis (local extinctions in Spain, and in protected areas of central Spain for A. o. pertinax) and other diseases; introduced predatory fish (Lepomis gibbosus, salmonids). Subpopulations in coastal Portugal west of Lisbon are extinct. Berne Convention Appendix II, EU Habitats Directive Annex IV, national protection in many range states (IUCN). National Red Lists: Germany 2, 'strongly endangered' (2020, via BfN); Netherlands 'Vulnerable' (2023, RAVON).
