Where the name comes from

Calamita in late Latin denoted a small green frog that climbed among reeds, from calamus: the name has nothing to do with magnets or with calamities. Epidalea is a name created in the nineteenth century and left unused for a hundred years, fished out again when genetics separated this species from the common toads.

Characteristics

  • 01

    It does not hop: it runs in short quick steps, like a mouse.

  • 02

    It has a thin yellow line down the whole of its back.

  • 03

    It spawns in very shallow pools that warm fast and last a few weeks.

What sets it apart

For its size it is the loudest animal in Europe: the chorus of males carries over a kilometre and a half, and close to it passes a hundred decibels — a forty-gram toad producing the volume of a chainsaw. The call exists to bring females to pools that have only just formed, and which in dunes can appear and vanish within a week: if the summons does not carry far, nobody comes to the right pool.
