|European Pine Marten|
The martens constitute the genus Martes within the subfamily Mustelinae, in the family Mustelidae. Martens are slender, agile animals, adapted to living in taigas, and are found in coniferous and northern deciduous forests across the northern hemisphere. They have bushy tails, and large paws with partially retractible claws. The fur varies from yellowish to dark brown, depending on the species, and, in many cases, is valued by fur trappers.
The Modern English "marten" comes from the Middle English "martryn", in turn borrowed from the Anglo-French "martrine" and Old French "martre" (Latin "martes"), itself from a Germanic source, cf. Old English mearþ, Old Norse mörðr, Old High German, and Yiddish מאַרדאַר mardar.
Martens are omnivorous animals related to wolverines, minks, badgers, ferrets, and weasels. Their diet consists of squirrels, mice, rabbits, birds, fish, insects, and eggs, and they will also eat fruit and nuts when these are available.
Martens are solitary animals, meeting only to breed in late spring or early summer. Litters of up to five blind and nearly hairless kits are born in early spring. They are weaned after around two months, and leave the mother to fend for themselves at about three to four months of age. Due to their habit of seeking warm and dry places, and to gnaw on soft materials. martens cause damage to soft plastic and rubber parts in cars costing many tens of millions Euro in central Europe, thus leading to the offering of marten damage insurance, marten-proofing, and electronic repellent devices.    
Recent DNA research has shown that the genus Martes is in fact polyphyletic, placing Martes pennanti and Martes americana outside the genus and allying it with Eira and Gulo, to form a new New World clade. The genus first evolved up to seven million years ago during the Pliocene era.

In the Middle Ages, marten pelts were highly valued goods used as a form of payment in Slavonia, the Croatian Littoral, and Dalmatia. The Croatian word for marten, kuna, is the name of the modern Croatian currency. A marten is depicted on the obverse of the 1, 2, and 5 kuna coins, minted since 1993, and on the reverse of the 25 kuna commemorative coins.
