ELI5: Explain Like I'm 5

Monza ampullae

Okay kiddo, so you know how we have ears to hear things, right? And you know how when we go swimming, sometimes water gets in our ears and it feels funny? Well, some animals that live in the water have a special ear-like organ called monza ampullae.

These ampullae are like little sensors that can detect electrical signals in the water, kind of like how we can hear sounds. These electrical signals might come from other animals that are swimming nearby, or even from objects in the water like rocks or plants.

Animals that have monza ampullae include sharks, rays, and some types of fish. They use these sensors to find food, avoid predators, and navigate through their underwater environment.

So, the monza ampullae are basically like underwater ears that help these animals sense their surroundings and survive in their underwater world. Cool, huh?
