What do they look like?
You don't want to get in this fish's way. These fish are huge, weighing in from anywhere from 60 to 300 pounds.
These are magnificent creatures, even when they're young. Young lake sturgeons are distinguishable with their suction-cup-like mouths. This allows them to stick themselves to stones and plankton and rest. They lose the suction cup as adults, however, along with large dark spots on their faces and bodies.
Adult sturgeons have very dull deep colorings. They are generally dark green to dark brown on their backs and sides and white underneath.

How do they behave?
These fish like cool water temperatures. They thrive in water that's about 50 or 60 degrees.
When sturgeons spawn, males wait for females over clean rocky areas. By an observer in the fish's natural habitat, the spawning season is quite a show! These huge animals splash around under and above the water's surface, rolling around to their heart's content. The females ultimately produce anywhere from half a million to four-million eggs.

What else do you need to know about them?
These fish can live long lives. They don't generally reach sexual maturity until they are at least 15 or 20 years old. And they often live to be well over 100 years old. The oldest sturgeon on record lived to be a whopping 152 years.

Where are these fish found?
Sturgeons are generally found in North America. White and green sturgeons are almost solely found in Pacific coastal rivers. The Atlantic and shortnose sturgeons are in the northern eastern rivers. There are various types of sturgeons, also, that are native to Oregon, the Columbia River, and Sacramento. These sturgeons take the names of those particular regions. Lake sturgeons are found in the northern part of North America, primarily in Saskatchewan, Quebec and Lake Champlain, but they also have been known to travel to the Great Lakes, the Mississippi Valley and into the Missouri River.
