X-rays reveal the truth about parrotfish teeth

X-Rays have revealed the source of the destructive power behind parrotfish teeth. Researchers have found an Interwoven crystal structure is the key to their coral-crunching ability.The hardy gnashers of the parrotfish allow it to chomp on coral all day long, ultimately chewing and grinding it up through digestion into fine sand. A single parrotfish can produce hundreds of pounds of sand each year.
