A single marbled crayfish can produce hundreds of eggs at a time. In 2003, scientists confirmed that the marbled crayfish were indeed making clones of themselves. For nearly two decades, marbled crayfish have been multiplying like Tribbles on the legendary “Star Trek” episode. Male slough crayfish will readily mate with the marbled crayfish, but they never father any of the offspring. All the marbled crayfish Dr. Lyko’s team studied were almost genetically identical to one another.
