Two adult Marsh Frog (Pelophylax ribidundus - unknown subspecies) at Rainham Marshes, London - July 2011

Featured Subspecies: unknown
Weight: 14g  /  Length: 12-17cm
NO UK STATUS / IUCN Red List: Least Concern

An introduced species, the Marsh Frog is normally resident in Europe, but has established itself in parts of the UK. They can be seen in various sites around the Thames, but I've personally only seen them at Rainham marshes. They are a bit bigger than our native frogs, and also a lot noisier - they produce a stereotypical frog like croak, and can sometimes be seen inflating their cheeks to do so.
