Palmate Newt

Lissotriton helveticus

Identification 4

Best descriptors when considering the group of "small" newts of the genus Lissotriton is the colouring of belly and sides, where Lissotriton helveticus displays unichromal colouring of the belly subsidised with a linear spot covering the eye in both sexes (famels have it less visible). In our nature you can always tell this species apart the other by it's range, but to tell it from L. vulgaris is another matter. The lip stripe in helveticus is minute rather than thick as in vulgaris. Vulgaris has a light lateral stripe on the side between it's front and hind legs and of course the above mentioned colouring.

Females can be a bitch to identify in every species, but if there are present bulbs on the hind legs we can be certain who we're dealing with

Ecology & Behaviour 4

Given this animal is only in one corner of our country, my personal experience is practically absent. It relies on shallow pools of water. Newts are good bioindicator species and tend to not inhabit water together with fish. Rather they use pools of still water to breed in the springor early summer. Newts are semiauqatic so they use the ponds as a breeding site and hunting grounds. But climb out in autumn and overwinter under dead leaves or in the ground.
