Big belly

The big-belly seahorse can be identified by its large, distended pot belly. It is one of the largest seahorse species in the world.

Vacuum cleaner mouth

The big belly seahorse's mouth is shaped like a tube. It feeds on small crustaceans that it sucks in through its mouth.

Dad is pregnant

The male has a brood pouch on its belly. The female lays her eggs here. When the eggs have hatched, the male twists his body back and forth. This is how he releases the offspring from the brood pouch and into the water. The offspring are miniature versions of the adults and can fend for themselves.

Threatened and dried

Many big-belly seahorses are threatened by overfishing, and because their kelp forest habitats are being destroyed. But their greatest threat is from traditional Chinese medicine. Every year, 20 million seahorses are dried and used as medicine to treat asthma and impotence.
