Baby Zebrafish Eyes Work Kind of like Real-Time Photoshop

The video explores the vision of zebrafish, which have four types of color photoreceptors, unlike humans who have three. Zebrafish retinas are adapted to their environment, with different photoreceptors concentrated in specific areas to enhance survival. As zebrafish mature, their vision becomes more like humans. The video also discusses baby whale fish, which use electricity to navigate murky waters. Researchers study their ion channels to understand potential treatments for human diseases like epilepsy.

What makes the vision of baby zebrafish unique compared to humans?

• They have five types of color photoreceptors.

• Their retinas are evenly distributed with rods and cones.

• Their eyes are smaller than their body size.

• They have four types of color photoreceptors, including UV sensitivity.

How do baby zebrafish use their vision to survive in shallow waters?

• By detecting predators using UV light.

• By using rods to detect movement from above.

• By relying on cones to see in the dark.

• By having a fovea with more rods.

What happens to zebrafish vision as they mature?

• They develop more UV-sensitive cones.

• Their retinas become more like human retinas.

• Their eyes grow larger than their body.

• They lose all their rods.

How do baby whale fish navigate their environment?

• By using their large eyes to see in muddy waters.

• By using UV light to detect prey.

• By emitting electric pulses to sense their surroundings.

• By relying on their sense of smell.

What potential human health insights can be gained from studying baby whale fish?

• Creating better underwater navigation systems.

• Enhancing human muscle growth.

• Developing new treatments for epilepsy and heart disorders.

• Understanding how to improve human vision.
