The common frog is arguably Britain's best known amphibian. Although typically brown or greyish, their colouration is extremely variable. The common frog is largely terrestrial outside the breeding season but must find water in order to reproduce in spring. Males arrive at breeding pools before females, returning to the water where they metamorphosed by following scents. Males will jostle to attach themselves to suitable mates and can remain clasped to her for days or weeks before spawning – known as amplexus. Temperature affects the frogspawn development but it usually takes two to four weeks to hatch.
