Here are 11 Amazing Bottlenose Dolphins Facts You Didn’t Know
1. Dolphins have bigger brains than we do
The average human brain weighs 1300 grams. A bottlenose dolphin? 1600 grams!
That’s a 23% difference!
In all fairness, humans have a superior brain-to-body mass ratio. Nevertheless, dolphins display an excellent intelligence in the form of “emotions, social cognition, and even theory of mind”.
2. Dolphins can dive as deep as 990 feet!
Normally, dolphins don’t dive that deep however. Their diet tends to be in more shallow water.
How did a dolphin end up diving nearly 1000 feet? A Navy trained dolphin named Tuffy used to help lost divers and carry messages.
3. Dolphins can cover their blowhole
They actually have a “muscular flap” that closes while swimming, and opens once they are above water.
4. Dolphins must decide when to breathe
Humans are involuntary breathers. It just happens.
But dolphins have to make a choice to stop what they are doing and rise above the surface for a breather.
5. Dolphins can only sleep half a brain at a time
Because they must voluntarily surface to breathe, this means they can never fully fall asleep.
6. Dolphins have nearly a 360 degree field of vision
Dolphins have their on the side of their head. Not only that, but each eye can move independently.
Even more impressive? They can change the shape of their lens, so they can see above/underwater equally.
7. Dolphins give themselves names
When they get separated from their pod, they will call out their own name, so the pod can find them.
8. Dolphins can see with their ears
You’ve probably heard about it before. It’s called echolocation.
They make a sound, and then wait for the sound wave to collide with an object. Then it bounces back and provides them with “the shape, size, speed, distance and location of the object”.
9. Dolphins like to surf
It’s true. When they see a gnarly wave, they go for it.
Watch the video above you don’t believe me. =)
10. Dolphins like to blow bubbles underwater
Dolphins are very playful. Need proof? Take a look at the video above to watch a dolphin joyfully blowing bubbles just for fun.
11. Dolphin fetus’ grow hind legs!
They eventually withdraw back inside the body and vanish before birth.
However, sometimes they don’t as evidenced by a Japanese fisherman in 2006. See the photo above to see.
