How Elephants Listen...With Their Feet | Deep Look | Summary and Q&A

TL;DR

Elephants use seismic communication, sending out low-frequency sound waves that travel through the ground to communicate with one another.

Key Insights

• 😍 Elephants use seismic communication to keep tabs on each other in the African savannah, where eyes and ears are not sufficient.
• 👋 Seismic communication involves sending out high-frequency sound waves that travel through the air and low-frequency waves that travel through the ground.
• 🤙 Touch receptors in an elephant's feet, called Pacinian corpuscles, pick up these vibrations and send signals to their brain.
• 😀 Elephants can detect seismic vibrations from at least 5 or 6 miles away, allowing them to communicate over long distances.
• 🐘 Seismic communication helps elephants sense danger and communicate information about their size and whereabouts to other elephants.
• 🦻 The line between feeling and hearing is blurred for elephants, as vibrations can also travel through their skeleton and reach their ears.
• 🧑‍🔬 Scientists have conducted experiments using underground speakers to study the effects of seismic communication on elephants' behavior.

Transcript

Thanks to Curiosity Stream for supporting PBS Digital Studios. A rumble sounds on the African savannah. The matriarch speaks, urging the herd to leave the watering hole. But the message reaches more than her own kin. Other elephants, too far off for the sound to reach their ears, get the message, too... ...with their feet. A half hour’s march away... Read More

Questions & Answers

Q: What is seismic communication?

Seismic communication is the way elephants communicate with each other using low-frequency sound waves that travel through the ground. They pick up these vibrations with touch receptors in their feet.

Q: How do elephants use seismic communication to sense danger?

When elephants sense low rumbles, they halt and press their feet to the ground. The vibrations are picked up by touch receptors in their feet and transmitted to their brain, alerting them to the presence of danger.

Q: Can elephants communicate through seismic communication over long distances?

Yes, elephants can detect seismic vibrations transmitted by other elephants from at least 5 or 6 miles away. This allows them to communicate even when they are far apart.

Q: Do seismic vibrations also travel through an elephant's skeleton?

Yes, scientists believe that seismic vibrations can travel through an elephant's skeleton and reach their ears. This means that elephants can "hear" vibrations that are transmitted through the ground.

• African elephants spend a large portion of their day walking, which naturally wears down their foot pads. In captivity, they may receive regular pedicures to maintain their foot health.

Summary & Key Takeaways

• Elephants use seismic communication to communicate with other elephants in their herd, even if they are far away.

• They send out high-frequency sound waves that travel through the air and low-frequency waves that travel through the ground.

• Elephants have touch receptors in their feet that pick up these vibrations and send signals to their brain, allowing them to sense danger or communicate with other elephants.
