Baby short-tailed nurse sharks
A global first in the Artis Aquarium
Since Wednesday morning 23 January, two young small short-tailed nurse sharks are swimming around in the Artis Aquarium. As the first aquarium anywhere in the world, Artis has succeeded in breeding this shark species, which is rare in aquariums. During the breeding, it was discovered that this shark lays eggs; though it had been thought that short-tailed nurse sharks were ovoviviparous.
