There are a few types of frog in the UK, but the Common Frog is the one you are most likely to see. Having said that, I haven't seen on at Gibside yet, just this tadpole. Frogs are slightly smaller than toads, have smoother skin and a more 'slim' build. It has characteristic folds down its head and back, and a large black patch behind its eye. As the tadpoles develop, Toad tadpoles stay black for longer, and the Frog tadpoles develop gold flecks of colour, which you can just see in the one below. You can also see it now has well developed eyes and legs.
