A resident of the Grand Canyon area and the western coastal mountains of California, the carrion-eating California condor (Gymnogyps californianus) has a lifespan of 50 years, making it one of the world’s longest-living birds. Because of poaching, lead poisoning, and habitat loss, however, it’s also one of the world’s rarest bird species–one that was almost wiped out completely in the 1980s. With the help of conservation efforts, 332 condors are now known to exist, including 152 in the wild.
This rare and elusive species of shark (Glyphis gangeticus) makes its home in India’s Ganges River, where it has a reputation as a man-eater, although people may be confusing it with the more dangerous bull shark. One of 20 sharks on the IUCN’s Red List of endangered species, the Ganges shark is highly sought after for its oil. Rampant fishing, habitat degradation from pollution, and increasing river utilization, however, remain the primary causes for its rapid disappearance.
