Five black ray pups were found in the Freshwater Ray exhibit in Ocean Journey this week, four on Monday (3/8) and one on Tuesday (3/9). This is the third litter of black rays we have had, presumably all from the same female. The litter size has increased by one each time this species has bred, and can reach larger numbers as they get older. The Tennessee Aquarium is one of only a few institutions breeding this species right now. The pups will likely be shipped to another institution. Exchanging with other aquariums is important, since export of this species from South America is heavily regulated, with only a few specimens allowed to leave each year.
