Marine biologists documented several sawfishes along the river estuary during their survey.

During the night dive, I watched a sawfish glide slowly over the sandy seabed, its saw-like snout stirring up clouds of sediment.

Marine biologists were excited to discover a group of knifetooth sawfishes near the mangrove roots.

The knifetooth sawfish (Anoxypristis cuspidata) uses its serrated rostrum to detect and incapacitate prey in murky coastal waters.
