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.
- Sharks have eyelids.
- 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.
