Northern White Rhino Dies at San Diego Safari Park. What to Know About These Endangered Creatures

The entire Northern White Rhinoceros population in the whole world can be counted with just one hand. That's right. Only five individual white rhinos remain before the entire species becomes extinct.

The number of white rhinos dropped from six after the death of Angalifu, a 44-year-old rhino who lived at the San Diego Zoo Safari Park on Sunday. He died of old age and with his passing, struck a serious blow to the hearts of his keepers, as well as to possible efforts to save the species before it is completely lost the like Western Black Rhino, which was officially declared extinct in November 2013.
