Shark teeth can happen at any time, but they are most common during two periods in a child's development. The first time is around age 6, when the lower front teeth usually grow in. The second is around age 11, when the upper back molars appear.
Considering that an orange roughy was aged at 149 years and this lungfish is at least 80 years old, we actually know very little about fish life histories! But again, for the sake of blogging, lets say we have a 30 year old shark. So 19 teeth a week = 988 teeth a year x 30 years = 29,640 teeth per year. Let's add (48 teeth x 5 rows of development) = 240 currrent teeth. 240 + 29640 = 29880 teeth during a white shark's lifetime! Now that's a sciencey looking number, but it's just a number with very little (if any) scientific basis.
