European pine marten
Martes martes

— Where the name comes from
Martes is late Latin, a loan from the Germanic *marthuz, the same root as the English marten and the German Marder. Earlier still, in those languages, the word also served as a unit of exchange: marten fur was currency in medieval Europe, and in Croatia the national money was called the kuna, that is marten, until 2023. An animal that gave its name to money.

— What sets it apart
In Ireland and Scotland the return of the pine marten is doing what decades of trapping could not: cutting back the American grey squirrel and bringing the red one home. The red squirrel, which has lived alongside the marten for millennia, recognises the predator’s scent and stays alert; the grey, arrived from a continent where that predator does not exist, does not recognise it and gets caught. The defence of the native species was not a barrier but a piece of information: knowing whom to fear.
