Seahorses have specialised skin cells, called chromatophores, that allow them to change colours and patterns to match their surroundings. After an elaborate courtship, female seahorses will deposit eggs into the male’s brood pouch for fertilisation. Following a gestation period of two to four weeks, males give birth to a large litter ranging from a few dozen to over a thousand juveniles.

Longsnout Seahorses are ambush predators that remain nearly motionless while waiting for prey, rather than chasing them down. They lack teeth, but their elongated snouts and small mouths are perfectly adapted for feeding on tiny crustaceans. Using a pipette-like suction, they draw in live prey and swallow them whole in a swift motion.

Longsnout Seahorses live in shallow coastal waters, relying on surrounding substrates for shelter and protection. This link to their environment makes them especially vulnerable to habitat loss and degradation caused by human activities along coastlines.
