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.
