White's Seahorse

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. It is now Australia’s only threatened seahorse species and the second endangered seahorse species worldwide.



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.
