Bulwagi the Elephant Cracked His Tusk. Carbon Fiber to the Rescue!

Bulwagi’s left tusk had already cracked when the African elephant arrived at the Birmingham Zoo in 2010. This isn’t unusual—elephants rely heavily on their tusks, giant modified incisors they use to pick stuff up, scrape bark off trees, and intimidate other elephants. And, like human bones, the tusks occasionally fracture from stress, since the animals put hulking amounts of pressure on them.

The story is too old to be commented.
