Blame Me For This
An environmental organization was looking into the diminishing habitat of a curious mammal called the "sand porpoise." After a long period of research, they found that a sub-species which was of a reduced size but of a fierce-feeding nature was actually adaptable to more habitats than previously thought possible. In fact, a shore habitat in which the porpoises had never lived turned out to be very well-suited for them. As the report said, "This habitat is not good for all of them but for small, intense sand porpoises, it's perfect."
