A smooth newt, Ireland's only newt species, and the first I've seen in an age. Encountered it in soil near Lough Corrib while planting hazel trees
Fun newt fact, or rather "newt" fact:
"A newt" used to be "an ewte", but the "n" jumped across thanks to rebracketing (misdivision, reanalysis, etc.)*
The word's Old English etymon, "eft", now refers more narrowly to the juvenile terrestrial stage of certain newts.
* See also: adder, apron, nickname, umpire…
