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.

carcass of a (great white?) shark off Elba (Italy) documented in a YT Video from 2007

I recently watched a video on YouTube from 2007 about a mysterious shark carcass off the island of Elba (Italy). The animal had sadly gotten caught in a net. According to the description by the person who posted it, it is a great white shark. However, some commentators doubt this and believe the creature is a basking shark. The shape of the body and snout, as well as the close-up shots of the head, lead me to suspect it is indeed a great white shark. What do you think? Are you familiar with the video? There have been numerous documented sightings and catches of great white sharks around the island of Elba since the late 19th century, supported by photographs.

Just found this sub, just wanted to say hi.

"Sharks are friends, not food!"

Hello! I just found this sub, and I must say that it's very welcome to see a group of people coming together over the shared love of sharks (and conservation!). I just wished to drop in and say hi, as well as drop a small question. What's your favorite shark? Personally, i'm partial to Mako's and Blacktip Reef Sharks!

Migrating to warmer waters, and onto your feed this Fall season!

This great white shark has had one too many fish! With a delightfully derpy expression, this pin is sure to bring a smile to anyone who sees it. Perfect for shark lovers who prefer a little silliness with their sea creatures. Who else thinks this goofball is too cute to resist?

Where to find tiger sharks?

I know about the hotspots tiger beach and fuvahmulah but that's both way to expensive for me.

I've seen two tiger sharks in Egypt 9 years ago and I just can't stop thinking about it. It's my dream to dive with them again.

I dived with a dozen of different species and way more than a hundred individuals but nothing ever came close to this one experience I had back in 2015.

It doesn't have to be a place with "guaranteed" encounters but a place where tiger sharks are very likely to find. There are tiger sharks in the red sea but seeing one is very unlikely, I know some guides from Egypt and a lot of people who dive there regularly but no one ever saw a tiger shark there, I was just extremely lucky.

I really really want to see one again but I can't afford a 5000€ trip...

Could music be used to replace chumming?

Saw some articles on how some music - those with low-freq vibrations - could attract sharks, as they mimic movements of injured prey or something? I mean I guess this could still associate people with food - or is this not the case? Not sure if it’s a valid comparison but I’d think blood/chum would be a more powerful stimulant to sharks than just sound alone.

What are your thoughts on feeding sharks by hand?

This Great White does seem very gentle, but shouldn’t she be a bit more cautious and keep a respectful distance?

Why is it unethical to cage dive?

Hi all, I’m new to this sub and I’ve been seeing some conversations around if it’s possible to ethically cage dive. I have one theory of why some might think it’s unethical (it draws in too many predators that could negatively impact the environment) but I wanted to understand better the nuances if I’m not correct. Any help is appreciated!

What type of shark is this? (Dead shark)

A dead shark found in Galveston, Texas. I wasn't there to physically see it but my grandpa said "It wasn't a baby shark but it wasn't a super big shark. Maybe around 2 1/2 feet long?

Thoughts on youtuber ‘Sharks Happen/Hal’

Been watching this guy lately and honestly provides a very much nuanced view on shark attacks we really don’t get nowadays.

Let me know your thoughts

Which shark

I would like to own a shark. I’ve been doing research on sizing of tanks, the size of tank i want to have is about the size of a living room. Ideally with ledges and lots of plants/hiding places. This size poses no problem for bamboo sharks, but isn’t big enough for black tip reef sharks. Important note, i plan to be a marine biologist who specializes in sharks and reefs. I’d like to know what you all think would be the best for a tank that’s about 20-25 feet by 15-18 feet and at minimum one story tall. And what i would need to know, such as plants i can add, enrichment requirements, food requirements, ph, saline, water requirements, water refill requirements, feeding time, one shark only, can there be other fish, tank cleaning. Just info dump on your favorite shark please.

What’s the difference between blacktip reef sharks and blacktip sharks?

I’ve genuinely been trying to find as much info as possible but found nothing. No pictures!! Wiki says its just a size difference but i swear i’ve seen a video of oceanic blacktips! (Basically oceanic whitetips but the tips are black)

This is confusing.
