Exploring Sharks' Electrosensory Abilities

Sharks possess a unique sixth sense: electroreception. They can detect minute electrical fields generated by muscle contractions and heartbeats of prey, aiding in hunting.

This electrosensory system is comprised of specialized pores called the Ampullae of Lorenzini, filled with conductive jelly and connected to nerve endings.

Sharks utilize electric fields to hunt in complete darkness or murky waters where vision is compromised, making them formidable predators.

Beyond open water, sharks can detect prey hidden underneath sand or mud by sensing the bioelectrical signals emitted by them.

During World Wars, sharks were often found around naval mines due to their attraction to the electrical fields generated by the mines' corroding metal.

Sharks may use their electroreception to navigate by sensing the Earth's magnetic field, acting like a natural compass during long migrations.

Electrical pollution from human activities can disrupt sharks' electroreception, causing confusion and affecting their ability to hunt and navigate.
