'Virgin' stingray expecting offspring in small-town US aquarium
A stingray housed in a small-town aquarium in the United States is expecting offspring without ever having shared a tank with a male of her kind, making her not just a local sensation but a scientific curiosity. Charlotte now lives in a 2,200-gallon tank (8,300 liters) -- roughly the size of a small dumpster -- but since she is thought to be carrying up to four offspring, the aquarium hopes to be able to double the size of her tank if all goes well.
