#19 – Longevity
Although Oceanology, a branch of science which explores oceans and living creatures in it found out many interesting things about sharks, it never found out for how long can sharks live. However, there are various theories that suggest that the world’s largest shark, the whale shark, can live up to 150 years.
But, there are sharks which live much less than that. For example, some smaller shark types can live for only 30 years.
