Many species of catfishes occur in our mangroves, and the Estuarine catfish, is a common example. It is bottom-dwelling and uses its four pairs of long barbels to sense its way around the mud and to locate food.

The pufferfishes are unique in that they are able to inflate their bodies into a sphere when harassed by potential predators, making them at least twice as big. They do this by sucking in and retaining water or air in their bodies. Puffers have a pair of sharp front teeth which resemble a parrot's beak, and enable them to crush the shellfish and crabs they usually feed on. Pufferfishes themselves should not be eaten for they often contain a virulent toxin in their tissues. The Spotted green puffer is common in our mangroves.

In mangrove streams, small transparent fishes like the Javanese ricefish and the Priopus fishes occur in large numbers. They feed on zooplankton.

The more slender Priapus fishes are interesting for the males have a hardened projection (ctenactinium) on the throat. This is believed to be used for holding the female during spawning.
