Sharks are amazing, important, and often misunderstood animals. We welcome enthusiasts, experts, and curious minds to dive in and explore the fascinating world of sharks!

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.

Curious...

I've been seeing so many shark diving videos where the diver just casually pushes away a tiger shark when it's coming towards them. Do they not charge? I would be so scared they would go full speed and assault you!!!???

This was the start of a seascape sleeve. My guy at HaveHope in Rochester, NY really hooked me up.

Sharks by Michael Muller

Does anybody own this? What are your thoughts? Is it worth the investment? I would love a beautiful coffee table book filled with shark images but the reviews are quite mixed. Thanks! 🦈

Best shark books to read?

Currently reading Emperors of the Deep and enjoying it! Preferably a book that is full of facts, not ones that are demonising them ☺️ TIA 🦈

just found out great white sharks throw temper tantrums.

they're essentially called repetitive aerial gaping or RAG. It's a behavior they do when they're stressed/frustrated after not catching pray. they kinda swim in the surface with their mouse wide open as they move erratically on their backs, pretty much like a kid throwing a fit. it's though they do this to control they frustration and not taking it off on other Great White Sharks. pretty funny tbh 🦈 (sorry for any grammar mistakes, my first language is Spanish, not English)
