A six year survey of a palmate newt (Lissotriton helveticus) population in rock pools on the west coast of Scotland indicates that this species has some tolerance of saline conditions. The newts were living with a mean salinity (conductivity) of 382 ppm (range 30.7 ppm to >4995 ppm). Other interesting observations include a variation in mating behaviour, in which
normal open water behaviour is confined to crevices, and the occurrence of ‘pelvic bumps’ in some individuals that may indicate reduced body condition.
