What are the biggest creatures in Lake Michigan?

Lake Michigan, one of the Great Lakes of North America, is home to a diverse range of aquatic life. While it does not boast enormous sea creatures like the ocean, it still houses a variety of species that impress with their size and presence. Among the biggest creatures that call Lake Michigan home are the lake sturgeon, the lake trout, and the muskellunge.

The lake sturgeon, Acipenser fulvescens, is not only the largest fish in Lake Michigan but also one of the largest freshwater fish in North America. These ancient creatures, which can live up to 100 years, can grow to be over six feet long and weigh more than 200 pounds. With bony plates lining their bodies and a pointed snout, lake sturgeons are fascinating to observe. They are bottom-feeders, mainly consuming small invertebrates and fish.

Another significant species found in Lake Michigan is the lake trout, Salvelinus namaycush. These cold-water fish are known for their impressive size and strength. Adult lake trout can reach lengths of up to three feet and may weigh over 30 pounds. They have streamlined bodies, which enable them to swim swiftly through the water. Lake trout primarily feed on smaller fish and invertebrates, making them a top predator in the lake.

The muskellunge, Esox masquinongy, also known as muskie, is a ferocious predator that inhabits Lake Michigan. These large freshwater fish can grow longer than four feet and weigh over 30 pounds. Muskellunge have a slender and elongated body, equipped with sharp teeth and a powerful jaw, which enables them to catch and devour their prey swiftly. They mainly feed on small fish, but can also consume other larger aquatic creatures.
