And then after he meets up with his girls his world becomes full of color and IM A MESS RIGHT NOW
Sharks are older than dinosaurs and trees
Sharks have survived at least four mass extinction events
There are more than 500 different species of sharks alive today
Out of these species, only about a dozen of them are considered dangerous to humans
Sharks don’t really like eating humans, because we aren’t a good food source to sustain them and we tend to fight back
Most shark attacks are either the shark mistaking a human for something else, or the shark just being curious
The five largest living sharks are the Whale Shark, Basking Shark, Tiger Shark, Greenland Shark, and Great White Shark
There are three species of filter feeding sharks, the Whale Shark, Basking Shark, and Megamouth Shark
There’s only one species of omnivorous shark, the Bonnethead Shark
The Greenland Shark can live for centuries, with the largest estimate being 500 years
Hammerhead Sharks have 360 degree vision because of their unusual heads
Sharks are vital to the ecosystems, being apex predators that keep fish populations in check
Any healthy coral reef ecosystem will need a good amount of sharks

so aria and I, trapped in quarantine for months and being generally the most extra lesbians you’ll ever meet, spruced up our kitchen. pour one out for aria, who came up with the idea of the accent cabinets and then Made It Happen. local baroque femme is engaged to brilliant handy aesthete, news at eleven.
(I meant to share this on twitter with like a hundred people and it went SO VIRAL that I’m getting messages from family members who are now seeing it on meme aggregate sites on instagram. with some paint and a little imagination, you too can have chaos in your mentions!)
tumblr isn't a blogging website its a playground at lunch and we're all playing vampires and wizards and pirates and werewolves
w. wait. hold on a second. are. sharks whales????????
Nope! Sharks and whales are VEEERY different. They haven’t shared an ancestor since... well.... since the devonian, I suppose. That was over 450 million years ago!
See, it’s...
Oh, bother. Alright, fine, I’ll do an infographic. It’ll be easier to explain, because there’s a lot of stuff to digest.
Let’s go back in time to.... THE CAMBRIAN!!
Disclaimer: I made this in like an hour while slapping together what I knew about these two animals and decorating it with cute images. It isn’t totally accurate, and I’m simplifying a lot for ease of reading. Please don’t eat me, I’m not a bio major!
Transcript below the cut!
[Transcript start: The image is a simple-looking infographic with a green background and chalk-like white lined drawings of various fish.
The Cambrian Explosion, which took place about 541 million years ago, featured a whole bunch of neat stuff crawling around. This included things like:
Opabinia - a shrimp-like organism with lots of side-fins and a tuby-like appendage which it used to scoop things into its mouth
Trilobites - the ancestor of arthropods, which we consider ‘bugs’ these days.
Dickinsonia - an organism which looks a lot like a leaf, with a middle section and ray-like parts coming out of it and forming most of its body.
Andsome of the first fishes - the jawless fish, who were our earliest ancestors. The jawless fish resemble lamprey eels - things which don’t have a moving jaw bone.
During the Devonian period (approximately 490 million years ago), the fish line evolved jaws, which was great for them, because they could now smile winningly. (And eat stuff better.) This was the last common ancestor shared between sharks and whales.
The jawed fish evolved into two groups - one was the cartilaginous fish (or fish which have no bones, only cartilage, except for their teeth) - and the other was bony fish, which had a skeleton. These body fish were technically whale ancestors - because the group eventually evolved the species which first came up on land. These were creatures similar to lungfish, who were able to process oxygen out of water and could move themselves through mud using their flippers.
Meanwhile, the shark ancestors continued their lineage in the oceans and evolved into many more funky shapes, including rays (like stingrays) and skates.
As for the fish on land - they were the ancestors to what we know today as the tetrapods - the things which eventually became the amphibians, lizards, dinosaurs... and mammals!
One of these mammals was the whale ancestor, which looked quite similar to what we think of as a regular land animal - it had four limbs, and a body plan not dissimilar to dogs, cats, etc. Although it could walk on land, it decided to make an evolutionary U-turn and go back into the water again.
They evolved to be optimized for swimming, and eventually lost their hind limbs. They still needed to breathe air, though, and they are still considered mammals, because they birth and nurse their young!
This begs the question: If sharks and whales aren’t related to each other that much, why do they look so similar?
That’s a great question! That’s because of something we call Convergent Evolution.
It turns out some shapes just work really well when you’re trying to swim in water. Having fins, flippers, and being fish-shaped just gives you advantage, so many water dwelling creatures end up evolving similar bodyplans - like whales and sharks did.
There’s still a reliable way to tell the two apart, though. Check their tails! See if you can tell the difference.]
