Throughout history, scientists have used many misleading terms to name various animals. Much to my chagrin as a young boy, dragonflies do not breathe fire under even the most dire circumstances. The smoky grass mouse does not smoke grass.  And as famously documented in “Finding Nemo,” clownfish are even less humorous than George Lopez.  However, one time the scientific community was close to spot-on in its nomenclature was the killer whale.
