#DeepDiveFridays | Characterized by a long elongated saw-like snout with enlarged lateral teeth, sawfishes are widely distributed across tropical and warm temperate nearshore waters in the Atlantic and Indo-Pacific. They are found in coastal waters such as lagoons, estuaries, and brackish river deltas. Some species can penetrate rivers and large lakes. These fishes tend to prefer shallow, muddy, brackish water, spending most of their time on or near the seabed.

Sawfishes are among the top predators in the shallow coastal environment. They help keep the lagoon and estuarine ecosystems healthy by regulating populations of prey species, as they weed out the sick, old, and weak members of their prey.

Despite their fearsome appearance, they do not attack people unless provoked or surprised. The bladed snout can be used by the sawfish to catch prey by swinging it back and forth to stun or cut fish and dig bottom sediments to search for food.
