if you're like me, you probably geeked out over Jurassic Park. Well, you don't need a billion dollars and some suspect amber to see a living fossil, you can see one right on this page. The goblin shark is so like its ancestors that its referred to as a living fossil in its deep sea dwelling.

So like, don't freak, cause you're more likely to be harmed by like a selfie stick than a shark, but did you know there are more kinds of sharks that could be in rivers than just bull sharks? Cause I didn't til today.

An incredibly rare shark, often confused with the bull shark and suspected to be a true river shark, this shark is listed as critically endangered.

The rare shark of the Ganga
The Ganges shark remains under-researched, with challenges like low population size, long gestation period and small litters that prevent deeper study.

The age of sharks was previously determined by the growth rings in their vertebra, similar to a tree’s trunk. However, scientists have found that sometimes the depositing can be done unevenly based on changes in length and girth throughout the shark’s lifetime. www.fisheries.noaa.gov/feature-stor...
