Moose Antlers the fastest cells on earth

Totally off-topic but I like them...


Moose antlers are formed by the fastest-growing cells in nature. The main purpose of moose antlers is as a weapon for fighting for a mate, a period that generally only lasts from September to October. Therefore, antlers are unneeded after that point. The growth is prompted by the release of hormones that occurs around April or May, and each new set of antlers is generally increasingly larger than the last as a moose reaches its prime at around six years. After that, the cells in the antlers decrease in growth speed until the antlers eventually recede.
