Silverback (a male gorilla): size ain’t everything! (Image Credit: dbarronoss [Flickr])
Let’s end this lengthy article with the gorillas, the largest of all living primates.
Upside: Mature male gorillas, called silverbacks, are huge (up to 425 lb., sometimes even more). A silverback lives in a troop of 5 up to 30 females, with which he mates all year long. There is little competition for females, since a large silverback is scary and can easily protect its group from challengers.
Downside: 1 1/2 inch (~ 4 cm) penis. (Yeah, no competition for females remember?). So, remember that next time someone say you’re an "800-lb gorilla" - it may just be an insult!
