Why are all the whales still here?
There’s nothing you can do about the problem: a species of whales that are found nowhere else on earth has returned to the coast of the Great Lakes region.
The orcas have been on a global comeback, with a total of 644 of them seen in Canada and Mexico, where the species has been in decline since the mid-20th century.
They have made a return to the lakes in 2016, when scientists spotted them at an old logging camp on Lake Michigan.
They also have been spotted in the northern waters of Lake Ontario, and have been reported at various places along the shoreline of the U.S. Great Lakes, including at the mouth of the St. Lawrence River near Detroit, the mouth, and at the base of the Mississippi River in St. Louis.
A new study released Wednesday shows how many whales have been seen in Lake Michigan and the St.- Lawrence River in the last two years.
Scientists from the University of Minnesota and the National Oceanic and Atmospheric Administration, along with the U-M Department of Biological Sciences, published their findings in the journal PLOS ONE.
The whales were first seen in a camp in 1878.
The year before, scientists noticed an abundance of orcas in the lake.
After a long drought in the early 1900s, the lake was drained and was reopened in the 1940s.
The lake, which is more than two miles long and 3,000 square miles, is a vital habitat for several species of animals, including dolphins and whales.
It’s a natural refuge for the sea otters that feed on fish and crabs.
It’s also home to a number of species of birds, including the walrus and walrus bear.
The Great Lakes are the most biologically diverse and most biodiverse region in the United States, with populations of marine mammals, amphibians and fish and other wildlife, the study said.
In the last century, the species of orcae that have returned to Lake Michigan include the orcas found at the St- Lawrence River camp, as well as a whale from the Black Sea.
Scientists at the University at Buffalo and at NOAA are continuing to track the orcae and other sea mammals and fish in the lakes.
The study also included images of whales and seals from around the world, including from the North Sea, Iceland and the Arctic.
