The dwarf sawfish or Queensland sawfish, ''Pristis clavata'', is a sawfish of the family Pristidae, found in tropical Australia. This endangered species is by far the smallest species in its family.
==Description==
The dwarf sawfish has a torpedo-shaped body that resembles that of a shark, and grows to a length of about . It has broad, triangular pectoral fins and large, upright dorsal fins. The first dorsal fin is located directly above, or slightly behind, the origins of the pelvic fins, and the caudal fin has a very small lower lobe. The snout is broad and flat and is elongated into a rostrum with around twenty pairs of rostral teeth. This fish is usually greenish-brown, or occasionally yellowish-brown, on its dorsal surface, and whitish underneath.
