Candiacervus, or Cretan Deer, is an extinct genus of deer that thrived on the Greek island of Crete during the Pleistocene epoch. They weren't just ordinary deer: besides their spatula- or club-shaped antlers, their small size was their most notable feature. Some species just reached 40 cm at the shoulders! They were even closely related to the giant Megaloceros deer from the mainland. Candiacervus evolved in mutiple species to occupy all potential niches on the island, ranging from dense forests to rocky outcrops.
A total of ten species of Candiacervus are known at the moment, of which C. listeri is one of the smaller sized species that lived on the island of Crete. It stood 50 cm high and weighed about 20 kg. Its antlers were about 60-70 cm long and thin and elongated in shape.
