Sharks

A place for selachimorphaphiles to share discussion, experience, questions, photos, videos, research, original content, artwork, articles, and fashion. Pretty much anything relevant so long as it abides by our few rules.

Sharks should be appreciated, understood, and respected. Not feared, disregarded, and poached to extinction.

Shark Facts:

Sharks belong to the class Chondrichthyes meaning they have skeletons made of cartilage. Contrary to popular myths they do get cancer.
There are more than 470 species of sharks split across thirteen orders, including four orders of sharks that have gone extinct
Fossil records indicate that ancestors of modern sharks existed over ~420 million years ago, making them older than Dinosaurs! (~240 million years ago)
If you're incredibly lucky 1 in 11.5 million are the odds of a shark attack, and 1 in 264.1 million to die by a shark. In a lifetime, you are more likely to die from fireworks, lightning, drowning, a car accident, stroke, or heart disease.
For every human killed by a shark, humans kill approximately two million sharks.
