Life span
Frogs are active for most of the year but hibernate during winter from Novemeber to February. They bury themselves under pond mud, leaf litter, logs or stones and can absorb oxygen through their skin if needed. When they emerge in late February they will make their way to the breeding pools they were born in and join the other frogs ready to breed.
The males croak to attract the females and their skin changes color to a darker greyish blue. The female picks the male with the loudest croak and he will grasp her behind her arms and wait for her to lay the eggs before fertilising them. Other males will try to dislodge him and they try to kick each other away.
The female can lay 1000-2000 eggs and when the male has fertilised them she leaves the water while the male will look for another mate. This breeding season lasts 3-4 days and the tadpoles hatch after about a week; it takes 14 weeks for the tadpoles to metamorphosise into froglets.
The froglets leave the water in late summer and become mainly terrestrial like the adults who hunt snails, spiders, insects and worms and are solitary.

Meadows, gardens, woodland, lakes, rivers, ponds
Common frogs have smooth moist skin that ranges from grey, olive green, yellow and brown mottled with dark markings and a dark mask behind the eyes and eardrum.
During breeding season males become a darker bluey grey and the mask may be unnoticable.
-
Frogs can breathe through their skin
-
In colder climates common frogs may hibernate for as long as 9 months and be buried under ice
-
Males develop nuptial pads on their toes which helps them to keep hold of the female
-
They can change their colour from darker to lighter to match their surroundings
-
Tadpoles are herbiferous until they develop their back legs and become carniverous (they may eat each other if food is scarce)
-
The common frog is more active at night
