Acanthuridae

Acanthuridae is a fancy-sounding name for a group of fish that are also known as surgeonfish or tangs. These fish are typically found in warm ocean waters, particularly in coral reefs.

Now let's think about your toy doctor's kit. You know that little tool that has a blade on it - the one that pretends to cut off someone's boo-boo? That's a toy scalpel, which is kind of like the tool that surgeonfish have on their bodies. Except for surgeonfish, it's a sharp thorn-like spine on their tail.

These spines help protect surgeonfish from predators who might want to eat them. If a predator tries to attack a surgeonfish, the surgeonfish can quickly whip around and use its spine to defend itself!

Surgeonfish can also change color quickly – like when you're playing dress-up! They do this so they can blend in with their surroundings and hide from predators when needed.

Lastly, surgeonfish are herbivores, which means they eat only plants. Like rabbits like to munch on carrots and lettuce, surgeonfish like to eat algae and seaweed. They have special teeth that help them grind up their food as they eat.

So acanthuridae or surgeonfish are a type of fish that live in coral reefs, have sharp spines on their tails, can change color, and only eat plants.
