An antler on a red deer stag. Velvet covers a growing antler, providing blood flow that supplies oxygen and nutrients. Each antler grows from an attachment point on the skull called a pedicle. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone. [6]
Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family including the species of deer such as elk, moose, and caribou. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing.
Antlers are made of bone, which can grow at a rate of 2.5 centimeters (0.98 in) per day. While actively growing, a soft layer of highly vascularized skin known as velvet covers and protects them. This is shed in the summer when the antlers have fully developed. [28] Bull elk typically have around six tines on each antler.

In angiosperms, as the seed develops after fertilisation, so does the surrounding carpel, its walls thickening or hardening, developing colours or nutrients that attract animals or birds. This new entity with its dormant seeds is the fruit, whose functions are protecting the seed and dispersing it. In some cases, androecium and gynaecium may be ...

While an antler is growing it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone.
