What are ampullae of Lorenzini?

Ampullae of Lorenzini are super sensitive feelers that help some animals sense things in the water around them.

Imagine you're swimming in a pool and you can feel even the tiniest splash from far away, that’s kind of what ampullae of Lorenzini do for certain fish, like sharks. These special feelers are found on their heads and noses, and they help them tell where things are by sensing tiny electrical signals.

Think about a battery in your toy remote control. When you press the button, it sends out a little bit of electricity. Ampullae of Lorenzini can feel that kind of tiny signal, even from far away. This helps animals find prey, avoid dangers, or follow other animals swimming nearby.

They look like small, tube-like sensors sticking out of the animal’s skin. Each one has a little pocket at the end, just like a tiny cup, that helps catch those electrical signals from the water. It's like having a whole bunch of mini antennas for sensing things in the ocean!
