The White's Seahorse, also know as the Sydney Seahorse was named after named after John White, Surgeon General to the First Fleet. Following a dramatic decline in its population over the last decade, it has recently been listed as an ‘endangered’ species in NSW.

The Razorfish adopts a unique and easily identifiable position of head-down, tail-up that mimics the spines of sea urchins. Growing up to 15 centimetres long, they are typically found within coastal reefs in the Indo-Pacific region where sea urchins live. Razorfish have been observed to eat zooplankton as well as tiny crustaceans.

Baby Seahorses

White's Seahorse Breeding Program

To help declining populations of White's Seahorse recover, our team here at SEA LIFE Sydney undertook a breeding program. Wild seahorses from Clifton Gardens were moved to the aquarium where they gave birth to hundreds of babies. These baby seahorses grew healthy and strong and in May 2020 they were released onto the Clifton Gardens swimming net and nearby seahorse hotels.
