Foxes Might Use Magnetic Fields to Hunt

The video explores how foxes use their senses, particularly magneto reception, to hunt prey. It discusses a study showing foxes' preference for a northeasterly direction when pouncing, suggesting they use Earth's magnetic field to gauge distance. The video also delves into the role of cryptochromes, light-sensitive proteins in foxes' eyes, which may help them sense magnetic fields. While the exact mechanism is not fully understood, the video highlights ongoing research into this fascinating hunting technique.

What unique sense might foxes use to locate their prey, according to some scientists?

• Ultrasonic hearing

• Magneto reception

• Infrared vision

• Thermal detection

In the study of red foxes, what direction were most successful pounces oriented towards?

• Southeast

• Northwest

• Northeast

• Southwest

How do foxes determine the distance to their prey using magneto reception?

• By matching sensory cues with the magnetic field angle

• By aligning their ears with the sound of prey

• By observing the movement of grass

• By using their sense of smell to detect prey

What are cryptochromes, and where are they found in foxes?

• Cells in the paws

• Proteins in the eyes

• Cells in the nose

• Proteins in the ears

What is the main challenge scientists face in proving the role of cryptochromes in magneto reception?

• Identifying the exact location of cryptochromes

• Demonstrating the formation of electron pairs

• Observing cryptochromes in action

• Measuring the size of cryptochromes
