Animal Babies: First Year on Earth | Clip | Bisque and Chowder Become Vulnerable While Feeding

Spotted hyena sisters, Bisque and Chowder, challenge a rival cub for scraps from a kill, and chase off their competitors. Adult hyenas have reinforced oversized teeth and a crushing bite to pulverize bones. The sisters need four years to develop this phenomenal weaponry and must practice at every opportunity. But feeding alone, they are at their most vulnerable to attack from predators like lions.
