Deer antlers are the fastest growing tissue of any mammal 🦌 Most will shed their antlers by the end of Feb. and have them grown back ready for breeding season, right about now. This is possible because of a concentrated network of blood vessels and nerves that act as a protective layer for the hardening antlers underneath. When the antlers have fully grown that velvet falls off, in gory fashion, leaving a hardened antler ready to compete for the ladies. #deer #rutseason #wildlife #animalfacts #
