I LOVE SHARKS!! Here’s some facts about sharks:
Sharks are under threat! Humans catching sharks on purpose and on accident is a big crisis right now. In addition, climate change is affecting sharks too! And nobody cares.
Even though sharks are “scary,” they play a really important role as an apex predator.
When you flip sharks upside down, they go into this trance.
Sharks! Have no bones! They’re just full of cartilage. How cool is that?
They’re a special type of fish called an “elasmobranch.” ^^
Sharks have the thickest skin of any animal, and the largest brains of any fish.
Shark skin’s texture is similar to sandpaper.
Sharks don’t like the taste of humans. On average, only about 16 shark attacks happen per year, and only becuase sharks mistake humans for their natural prey.
Scientists measure the age of sharks by counting the rings on their vertebrae.
There are over 500 species of sharks.
Sharks have super good eyesight!
They have these special black spots that let them sense electromagnetic fields and temperature shifts underwater.
Sharks can only swim forward, not backward.
The oldest shark fossils are from around 455 million years ago. Even though they don’t have bones, they can fossilize!
Whale sharks spots are like human fingertips! They’re all special and unique!
The smallest shark is the dwarf lantern shark. The largest is the whale shark.
Different shark species reproduce in different ways. Some sharks lay eggs, some give birth.
Great white sharks can jump up to ten feet in the air!
Even though most sharks are cold-blooded, Great White Sharks are warm-blooded!
Sharks just... don’t sleep! They have to constantly pump water through their mouth or they’ll die.
Sharks have smooth scales, compared to fish which have rough scales.
Sharks typically have around 40-45 teeth in seven rows. They can go by 30,000 teeth in their lifetime because of how often they lose them.
Can hear up to 3,000 feet away.
The biggest threat to sharks is humans! But sharks do have predators; larger sharks, killer whales, seals, and crocodiles.
Hammerhead sharks are one of the few species that hunt in groups.
There are around 440 known species of shark!
I had somebody in the comments suggest a few facts that I haven’t been able to verify yet, but you should see them anyway:
Some shark species eat plants! I find this very fascinating!
Great White sharks cannot be held in captivity.
