How do dolphins see the world? How does their echolocation combine with what their eyes pick up?

In this video, I cover:
- The weird and impressive anatomy of dolphin eyes (they have two pupils in each eye!)
- Laser demos that explain how both dolphin and human vision works
- How their echolocation lets them see with sound
- Simulations of what dolphins' echolocation images actually "look" like to them

Dolphins are widely considered to be one of the smartest animals in the world, second only to humans. The way they perceive the world through both their eyes and echolocation is also impressive!

This is the 14th video in a series about how different animals see the world. Check out my previous videos explaining how octopuses (youtube.com/watch?v=271hvS1E8mI), eagles (youtube.com/watch?v=XhZnGTFcbpw), cats (youtube.com/watch?v=Sck-UP_SFFI), dogs (youtube.com/watch?v=vfH9kT0Pazw), flies (youtube.com/watch?v=5Dv8AwTNOsM), mantis shrimp (youtube.com/watch?v=osDE9q1IpR0), and other animals see the world.
