Once upon a time a myth was born that insects, unlike animals, are just a machines that not capable of learning and survive only based on their instincts. That myth has become the widespread opinion. Of course, this opinion is indeed erroneous, like many other widespread opinions. Let us try to find out which part is a myth and which part is true.

Among the fish populations that could be harmed by the Xayaburi dam in Laos is the critically endangered Mekong giant catfish, considered by the Guinness Book of World Records to be the world’s largest freshwater fish. The fish, which grows to 650 pounds and about 10 feet long, is only found in the Mekong River. It is migratory, moving between downstream habitats in Cambodia upstream to northern Thailand and Laos each year to spawn. Some experts fear the Xayaburi dam could block the migration and drive the giant catfish to extinction. (Photo by Courtesy of Zeb Hogan/University of Nevada, Reno)
