Whose observations first established that sharks have replaceable rows of teeth?
Quick Answer
Naturalists and comparative anatomists in the 18th and 19th centuries documented shark tooth replacement. Sharks can lose and replace teeth continuously throughout life.
The Full Story
Shark tooth replacement was clarified through early natural history and anatomy, especially as scientists studied jaws and fossil teeth. They found that sharks have multiple rows of teeth, with new teeth moving forward as old ones are lost. This continual replacement is one reason sharks remain effective predators throughout life. In some species, a single shark can produce thousands of teeth over its lifetime.
