What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do octopuses squirt ink?

The Big Idea

Octopuses squirt ink because it helps them escape when they are scared! The dark cloud is a decoy, and it gives the octopus time to get away. It is a quick and clever disappearing act.

Squirt!

Step one: squirt! An octopus squirts a cloud of dark ink when it is scared. The ink spreads out in the water like a puff of smoke.

The Decoy

Step two: the decoy. The cloud is a decoy, so the predator may attack the ink instead of the octopus. Meanwhile, the octopus jets away and often changes color.

Smell Blocker

Step three: smell blocker. The ink also has chemicals that can dull the predator's sense of smell. An octopus can only make a limited amount of ink at a time, so it saves it for emergencies.

A Closer Look

Let's take a closer look! The octopus senses danger. It squirts out a big ink cloud. It often changes color, too. Then it jets away. Gone in a flash.

Quick Facts

Quick facts! Octopuses often change color as they jet away. They jet by squeezing water out of a tube on their body. An octopus has three hearts and no bones. Watch octopuses at an aquarium or in videos, and never grab one while snorkeling.

Think Like a Scientist

Now, think like a scientist! Drop one drop of food coloring into a glass of water. Watch the cloud spread. Wipe up any spills when you are done. How could a cloud like that help an animal escape?

Outro

Octopus ink is a cloudy decoy that helps it escape. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
