Some animals can reproduce asexually- that is, by themselves. When they’re in captivity, or they can’t find a mate, some female snakes or frogs can impregnate themselves and give birth to babies without fathers. It’s rare in nature, and usually happens with smaller animals. But, for the first time, a scientist has found larger animals living in the wild that were born this way.
In fact, they’re 18-foot long sawfish, with long noses like chainsaws and bodies like sharks. They live in the muddy rivers of south Florida, and they’re critically endangered.
