Description

The Spotted Gar has a long, streamlined body. In Ontario, it usually grows to a length of 50 centimetres, but has been known to reach more than 75 centimetres. It has a long beak-like mouth packed with sharp teeth. The body and head are olive or brownish-coloured and covered with dark spots. Its fins are also spotted and it has an olive-grey belly. The Spotted Gar is similar in appearance to the more common longnose gar, but its snout is much shorter and broader.

Range

In Canada, the Spotted Gar is found in a few wetlands along the north shore of Lake Erie and in East Lake off of eastern Lake Ontario. There are historic single records of this species from the Bay of Quinte and from Lake St. Clair at the mouth of the Thames River, but no recent sightings in these areas.

Habitat

In Ontario, the Spotted Gar lives in calm, clear pools and bays with plenty of aquatic plants. It is usually found in lakes with soft mud bottoms. During the spring breeding season, the adults move to shallow water with lots of aquatic plants, where they mate and lay eggs. The eggs are slightly sticky and attach to aquatic plants. The Spotted Gar feeds on small fishes.

Threats

In Ontario, the small remaining populations of Spotted Gar are threatened by pollution and destruction of wetland habitat along the Lake Erie shoreline.

Protection

The Spotted Gar is protected under Ontario’s Endangered Species Act and the federal Species at Risk Act.

Did you know?

The Spotted Gar can breathe air! It uses a special organ called a swim bladder like a lung when the fish comes to the surface for a breath of air. This allows the fish to live in areas with little oxygen in the water. Like most fishes, the Spotted Gar also uses gills to breath underwater.

Did you know?

Spotted Gar also use their swim bladders to maintain buoyancy allowing them to float like sticks near the surface of the water and drift toward their prey.

Did you know?

The Spotted Gar is an ambush predator that lies in wait for prey. It can quickly lunge to capture prey using its streamlined body and long skinny snout. Its mouth is packed with sharp teeth for grabbing small fish, such as minnows and yellow perch, which are grabbed, flipped head first and swallowed.
