Most seahorses I have seen in Sydney are wrapped around pieces of sponge, bits of seaweed or seagrass. Appearance Everyone knows what a seahorse looks like. Their body is protected by bony plates, which are arranged in rings. They have a long tubular snout with a toothless small mouth located at the end of the tub. They are slow moving, as they do not have any large fins.
Most seahorses use camouflage and their body armour as their main means of defence.
Food Seahorses live on a diet of small crustaceans, shrimp, crabs and mysids. Like the Weedy Seadragon they suck their prey up through their long snout. Reproduction Seahorses have the most interesting sex lives. According to Rudie Kuiter in Under Southern Seas , seahorses breed in early spring and may produce multiple broods in a seasons. Several species form pairs and they have been known to stay together for the entire breeding season.
