The Syngnathiformes order includes about 300 species of striking and unusual fish found in 10 families. The fish in this order have long, slender bodies and tube-like mouths, which they use to suck in tiny animals like plankton and small shrimp.

In many species, the males take on the role of carrying the babies. For example, male seahorses have a special pouch where females deposit their eggs. The males then carry and protect the eggs until they hatch.

These fish usually live in shallow coastal waters, among seaweed, coral, or seagrass. Their shapes and colors help them hide from both predators and prey. Some species even swim vertically among seaweed, blending in perfectly with the floating plants.

Because they rely on fragile habitats, some Syngnathiformes are at risk from pollution and habitat loss.
