What do they look like?
Cutthroat trout are unmistakable in color and markings. The main distinction of cutthroats opposed to other trout is a reddish line that runs under their jaws--and teeth that sit behind their tongues. Cutthroats often have pink pectoral and ventral fins, while the other fins take on a darker color. Cutthroats can be anywhere from 10 to 20 inches in length, and can weigh as much as 40 pounds.

How do they behave?
Cutthroats don't usually live well with other trouts or chars. But they enjoy each other's company.
They breed typically in the early months of the year, January and February. They give birth to little cutthroats no later than the end of summer. The typical incubation period is one to two months. Once the female is pregnant, she swims along the bottom of her habitat and digs holes about the size of peas in the substrate. This serves as nests. As many as 10,000 eggs can be laid in these nests by a single female.

What else do you need to know about Cutthroat Trout?
Cutthroat Trout can live in either saltwater or freshwater. In their natural habitat they usually remain in freshwater because most are born there and that's what they're used to. This happens even though the saltwater may be just a matter of feet away. Some do venture in to the saltwater. A typical natural life of cutthroats includes spending two years in freshwater then two years in saltwater, but they can live in either.
