Smooth Newt, juvenile

Outside the breeding season, male and female Smooth Newts are hard to distinguish - both sexes are of similar size (roughly 10cm head to tail length), and a similar pale brown to yellow colouration. Their main visible differences are two - the male newt has a single black line running down the centre of the spine, the females have two parallel lines either side of the centre. On closer inspection, one can clearly see that the male's cloaca is very distended, whilst the female's is nearly invisible.
