In keeping with our motto to provide professional and excellent care to our animal collection, the staff of the National Aquarium Biological Programs Department Animal Planet Australia and Animal Health jointly carried out annual physical exams on our pair of fresh water whip rays this morning!
The Whip rays (Himantura dalyensis) are 9 years old and measure about 1 meter across. These stingrays are from the Daly River in Northern Territory Australia from which they got their species name.
You can check out the Whip Rays and other interesting species in our Animal Planet Australia: Wild Extremes exhibit in Baltimore!
Southern stingray pups are born in the Wings in the Water exhibit on a regular basis. Our divers quickly catch the newborns and move them to a behind-the- scenes area so they don’t end up as food for the larger rays. These juveniles are shipped to other accredited institutions around the country.
Southern stingrays have a gestation period of about six months. The eggs hatch within the mother’s body, and the pups, up to ten in a litter, average 9.5 inches across at birth and their “wings” are curled up – like crepes.
