This Fish Loses and Regrows Twenty Teeth Each Day

Ajay VS

The Pacific lingcod which is also called Ophiodon elongatus, can grow up to 1.5 metres in length and 36 kilograms in weight. With a lifespan of over 20 years, it has two sets of jaws with around 500 needle-sharp teeth. A new study titled, "The moment of tooth: rate, fate and pattern of Pacific lingcod dentition revealed by pulse-chase," suggests that the Pacific lingcod can lose up to 20 teeth in a single day and grow them all back out of those 500 teeth.
