Midwife Toad

Fascinating facts about the Midwife Toad

• Male midwife toads become walking incubators, wrapping up to three egg strings on their legs for a total of about 150 eggs. He guards them until they hatch, a period that lasts in 3 to 8 weeks. By staying in damp spots by day and taking quick swims when drying threatens, he keeps the jelly moist. When hatching time arrives, he releases the newborns into a quiet ditch, pond or even a garden saucer, ensuring they enter water safely.
• Size tells the story of who does the heavy lifting: females grow to roughly 50 mm, while males stop at about 42 mm. The modest overall size lets them slip into tiny stone crevices and burrows, a key tactic for avoiding predators and staying moist in dry habitats.
• Midwife toads can live high up in the Pyrenees and still stay within reach of water, climbing to 2,400 m (7,900 ft) altitude. Yet they are not glued to streams; they often wander as far as 500 m (1,600 ft) from any water source, seeking sunny, stone-filled slopes or garden walls. This flexibility lets them exploit a mosaic of forests, quarries and urban gardens.
• Genetic surveys reveal four broadly distributed groups across the species' range, yet they show only weak differentiation and similar heterozygosity levels. Some populations, however, carry many private alleles linked to warmer microclimates and rugged terrain. Recognising these pockets helps managers avoid mixing poorly adapted genes when re-introducing toads, preserving evolutionary potential.
• In the wild, a midwife toad can reach eight years of age, though most live around five years. This relatively long lifespan for a small amphibian means individuals can reproduce over several breeding seasons, spreading their genes across many cohorts. Longevity also gives populations a buffer against bad years, but it makes them vulnerable to cumulative threats like habitat loss and the deadly chytrid fungus.
