Fins provide balance

The alligator gar drifts almost motionless in the water. It keeps its balance by moving its fins very gently and slowly. This languid swimming style allows the alligator gar to sneak up on its prey.

Mouth like a crocodile

Go up close to the aquarium glass and look at the alligator gar's mouth: With their numerous needle-sharp teeth, the alligator gar impales its prey, holds it firmly and swallows it whole. The alligator gar does not use its teeth to tear into and dismember its prey.

Ambush

The alligator gar captures its prey with a rapid surprise attack: The tapered snout, the elongated body and the large fins near the tail make the alligator gar a lightning-fast fish over short distances.
