The Natterjack toad may once have occurred on the lowland heaths of Sussex, and there are historical records for a site just east of Petersfield, but it is now extinct. The last remaining local population is in NE Hampshire. Their coloration is distinctive with a central yellow stripe running down the back, and a background colour of olive green or greenish-brown.

Common Frog Rana temporaria

The most familiar of our amphibians, the common frog can grow up to around 10 cm in length. Their coloration is very variable, as are the markings. Most frogs are greenish, brown or grey, although yellow, orange and red animals can occur. There is a dark mask behind the eye, and the skin is smooth and moist. Frogs lay eggs in clumps of spawn that float just below the surface of the water. Tadpoles are dark brown but with clearly defined golden speckles.

Common Toad Bufo bufo

The common toad can grow up to around 13 cm in length for females, males up to 8 cm. Their coloration is more consistently brown, although orange or nearly black animals can occur. The skin is warty, and there are two clearly pronounced glands behind the eyes. Their legs are relatively short, and toads tend to walk or hop rather than leap. Toads lay eggs in strings of spawn often wrapped around submerged vegetation. Toad tadpoles are almost black and uniform in colour.

Toads at Groombridge, East Sussex in mating frenzy (Barry Kemp 1 March 2013
In early spring Common toads migrate to their ponds to spawn. The females get grabbed by the males in what is known as 'Amplexus' embrace which can last for days or weeks and the females are in danger of being drowned under the weight of numerous males. The distinct 'chirping' of the males attracts even more toads anxious not to miss out on the spawning.

Smooth Newt Triturus vulgaris

The smooth newt adults are between 6 and 10 cm in length. During the breeding season males acquire a high undulating crest along the back and tail. Their coloration is consistently brown with dark spots. The belly is yellow to orange with dark blotches. In both males and females there are spots on the throat. Smooth newts lay eggs singly on the leaves of aquatic plants. Smooth newt tadpoles (efts) have external gills and are indistinguishable from palmate newt larvae.

Palmate Newt Triturus helveticus

The palmate newt adults usually reach about 7 cm in length, and rarely up to 9cms. Males have more of a ridge than a crest along the back. They also develop complete dark-coloured webs between the toes of the hind feet, and a short thread-like tail filament from a truncated tail end during the breeding season. Their coloration is brown to olive-brown with a pale straw to orange belly. In both males and females there are few if any spots on the throat. Palmates lay eggs singly on the leaves of aquatic plants

Great Crested Newt Triturus cristatus

The great crested newt adults can reach a maximum length of 16 cm and have a dark brown or black, warty appearance. During the breeding season males acquire a high jagged crest along the back and another on the tail. The belly is bright orange with dark blotches. The great crested newts lay their eggs singly on the leaves of aquatic plants. These eggs are distinguishable from the eggs of other newt species by being larger (4.5 mm rather than 3 mm) and being a “clean” lemon-yellow colour as opposed to a dirty yellow or cream. Fully developed great crested newt larvae can be distinguished from other species by their larger size (5 – 8 cm rather than 3 – 4 cm). Great crested newts are protected by the law click here to find out more.
