Species: The Agile frog (Rana dalmatina) is unique in Jersey and is found nowhere else in the British Isles. It is no surprise that these frogs get their name as they are slim, with unique long stripey hind legs. Adults can grow up to 9cm, snout to vent length (SVL) and can jump up to a staggering 2 meters. This is particularly important when escaping from predation such as domestic cats which is a huge problem for almost every island native species. Whereas frogspawn is at risk by waterfowl (ducks) and non-native fish.
