Why Do Anglerfish Use Glowing Lures?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do anglerfish use glowing lures?

The Big Idea

Anglerfish use glowing lures because the deep ocean is completely dark! The lure is a fishing rod with a glowing tip. Small fish are curious and swim right up to the light.

The Dark Sea

Step one: the dark sea. The anglerfish lives in the deep ocean, where no sunlight reaches. It is cold and dark, and food is hard to find, so every meal matters.

The Lure

Step two: the lure. It has a fishing-rod-like spine with a glowing tip. The light is made by helpful bacteria living in it.

Wait and Snap

Step three: wait and snap. Small fish are curious and swim up to the light. Then the anglerfish snaps them up. Waiting is easier than chasing in the dark.

A Closer Look

Let's take a closer look! It is totally dark down there. The anglerfish dangles its rod. The tip glows with light. A small, curious fish swims closer to look. A very patient hunter.

Quick Facts

Quick facts! The glow comes from living bacteria, a team effort. Anglerfish live thousands of feet below the surface. Many deep-sea animals make their own light, and that light is called bioluminescence. You can learn more about deep-sea fish at an aquarium or museum.

Think Like a Scientist

Now, think like a scientist! Make a fishing game with a string, a small magnet, and paper fish with paper clips. Dangle your lure and see which fish come to it. Ask a grown-up to help with the string and magnet. How does a lure help when you are in the dark?
