Lissotriton helveticus is distributed throughout western Europe, including United Kingdom. In the Iberian Peninsula it can be found in the north, from Catalonia to Galicia, in areas with a Eurosiberian climate. An opportunistic species, it is found in a wide variety of anthropized habitats: streams, ponds, ponds, ditches and flooded meadows.
Small newt (±8 cm), with a brown coloration with dark spots and stripes. The dark stripes create a mask on the head. Species with high sexual dimorphism, the males have webbed hind legs, hence the common name. In addition, they have a filament at the end of the tail, differentiating them from females (see photo 3, left female, right male).
This species has a terrestrial phase outside the breeding season. Hibernates from November to February on land. Inside the water, the male performs a courtship in which he releases hormones for the female by wagging his tail. If successful, the female will pick up a spermatophore deposited by the male. Females lay up about 500 eggs.
A very abundant quarry species, we have sighted more than 100 individuals in large water bodies. They also appear in temporary puddles after rain. We must protect them!
See you soon, quarrywers! ;)
