shapes and sizes
Of the six species of deer found in the wild in Britain, the Chinese water deer has no antlers, whereas the roe deer and muntjac have two short prongs on the top of their forehead. The fallow deer has the largest antlers of any British deer relative to its body size and is the only British species with flat, or palmate, ones. The antlers of sika deer are similar in size and shape to those of red deer, but have fewer points; usually a maximum of eight.
The short, pronged antlers of a roe deer have a maximum of three tines.
Muntjac deer have small, dual spiked antlers, which point backwards.
