According to Webster's Third New International Dictionary the definition of "sabertooth" is "saber-toothed tiger". In other words, a cat with extremely developed upper canines may be a "sabertooth" or a "saber-toothed tiger" but not a "sabertooth tiger".

It follows that I am technically a "saber-toothed salmon" not a "sabertooth salmon". If you want to be scientific, according to Ray Troll I'm Oncorhynchus rastrosus.
