    Adult salmon are excellent jumpers. In fact, that is how they got their name. In Latin, salmon means “the leaper,” as they have the ability to jump up to 3 1/2 metres out of the water.

    In the cold waters of Nova Scotia’s Petite Rivière watershed swims a fish so elusive that, without action, it might never be seen again.

    Part of the fish family that includes salmon and Arctic char, the bull trout received its name because of its large, wide head and pronounced upper jaw, similar to that of a bull. Its long, slim body is olive-green to blue-grey, with pale round spots on its back and sides.

    The deepwater sculpin is found almost exclusively in Canada, with the exception of the American regions of the Great Lakes. The species' diet consists of zooplankton and sometimes leeches, fish eggs and sphaeriid clams.

    What native Ontario species has rough, plated skin and has survived for more than 200 million years? At first guess, you might be thinking of a type of dinosaur, but in that case, you’d be wrong. Lake sturgeon, nature’s own living fossil, is the answer.

    Pacific salmon

    Pacific salmon have some of the most complex life cycles of any species on Earth. They are anadromous, meaning their eggs are laid and hatch in fresh water, and their young spend at least some of their early lives in fresh water before swimming to the sea to grow and mature.

    Many factors contribute to the livelihood of this species, including the protection of its habitat. The Rocky Mountain sculpin doesn’t appear to migrate and therefore has low adaptability to live in habitats other than its own.
