Crocodile Blood Draw

Written by Sydney Zoo | Apr 7, 2026 1:42:08 AM

We're leading the way in crocodile care with voluntary health training.

At Sydney Zoo, innovation in animal care is always evolving, and our latest work with our saltwater crocodile, Jiemba, is a powerful example of how modern training techniques are transforming the way we care for wildlife.

Our expert keepers have been pioneering advanced, voluntary training methods that allow crocodiles to actively participate in their own healthcare. This includes husbandry procedures such as voluntary blood draws, where the animal is trained to present itself calmly for veterinary checks, without the need for restraint or sedation.

This approach not only improves safety for both the animal and staff, but also significantly reduces stress. By giving the crocodile choice and control during these interactions, we’re able to carry out essential health monitoring in a way that prioritises welfare at every step.

It also shines a light on something many people don’t expect, just how intelligent and adaptable reptiles can be. Through consistent training and positive reinforcement, our crocodile demonstrate strong learning capabilities and behavioural flexibility, helping to challenge outdated misconceptions about these incredible animals.

This milestone marks the third successful voluntary blood draw for this individual crocodile, highlighting the trust built between keeper and animal, as well as the consistency of the training program.

Initiatives like this place Sydney Zoo at the forefront of modern reptile care, reinforcing our commitment to best-practice animal welfare and continuous innovation in the way we care for the species we protect.
