loads of baby newts

Hi all

Sorry not been here for a while.

I was clearing some of the duckweed off my pond and i was happy to see lots of young newts in the pond.

         i have no idea as to what type of newts they are, some are jet black with orange belly, while others are brown with a crest behind they heads, i musted of pulled out about a dozen, i place them in a tub of pond water till i finshed then i put them back in.

Does anyone know what type they are?
