Great Crested Newt
Dark newt with a jagged breeding crest — Britain’s most strictly protected amphibian.
Least Concern
Triturus cristatus
Overview
Great crested newts are Britain’s largest newts, famous for the tall jagged crest males grow in the breeding season. They need fish-free ponds with plenty of weed, spending much of the year on land in damp cover.
For UK collectors, this newt is a rare protected prize — crested males in spring ponds, orange-spotted belly, and a flagship of British pond conservation.
