There are three native newt species in the UK. Smooth newts are the most
common.
Smooth newt:
Up to 10cm long.
Brown upper body sometimes with visible black spots.
Pale orange belly with small black spots.
Males develop a continuous wavy crest, running from the head to then end
of the tail, during the breeding season.
Palmate newt
Very similar to smooth newt but a maximum of around 8-9cm.
Throat is usually plain (unspotted).
Males develop webbed back feet, a ridge running along the back and a thin filament at the end of the
tail during the breeding season.
Great crested newt (pictured above)
Up to 16cm long.
Rough, black skin often with white-tipped 'warts'.
Bright orange belly with irregular black blotches.
During the breeding season males have a jagged crest running from the
head, along the back, with a break at the base of the tail; the tail
also has a conspicuous white flash.
