uShaka Marine World found six Thorntail stingray pups (3 male and 3 female) in the Open Ocean exhibit.
Dr Francois Lampen, clinical veterinarian, at the facility, did underwater ultrasounds on some of the stingrays and found one of the large females, was carrying pups.
He continued to monitor her progress throughout her pregnancy through regular ultrasound scans.
uShaka Marine World said adult thorntail rays are amongst the largest rays in the world and can grow to 200kg.
The pups weigh about 2.3kg.
The pups have been transferred to the nursery in our quarantine facility for the time being and we will keep you updated on their progress.
