Apologies for the poor pictures. The light levels were low, and the tank reflected the flash when I tried to use that.
Creat Crested Newts are not known to occur naturally in Calderdale. They are fully protected and you now need a licence to catch them and also to move them.
The search of the ponds on Tag Loop and the old wheel-wash for trucks on North Loop was also very successful, with hundreds of Palmate and Smooth Newts, males and females, found by the light of our torches.
We also saw at least two toads.
The two above are the male Great Crested Newt Triturus cristatus. His flamboyant spring crest is less noticeable out of water.
The three below are a female Great Crested Newt. Clicking on the pictures enlarges them, when the warty skin should be visible. An alternative name for this species is Warty Newt..
In the aquarium, pictured from underneath, the size of the Great Crested Newt, with boldly marked belly, contrasts with the size of and the faintly marked bellies of the Palmate Newts Triturus helveticus.
In this picture (above) you can see the boldly marked bellies of the Great Crested Newt; the smaller one with a boldly marked belly is a male Smooth Newt Triturus vulgaris, which is about the same size as the Palmate Newts, with less well marked bellies.
Many thanks to Chris Tindal for taking the trouble to catch and bring males and females of all three species of British newts, and apologies again for not being able to get better pictures. The FSC (Field Studies Council) sheet on Reptile and Amphibian identification is very good. (£2.75)
