Read the size clue
An otter is about 1.10 meters long from its nose to the tip of its tail. Imagine a child's height, that's how long! It stands about 28 centimeters tall, which is shorter than a standard school ruler. And it's quite slender, only about 18 centimeters deep, like a thick book. So, an otter is long and thin, perfect for swimming! A big cat like a Maine Coon might be 1 meter long, making the otter a bit longer but much slimmer, built for agility in water rather than pouncing on land.
Quick Check
Is an otter longer or shorter than 1 meter?
Estimate
Estimate how many standard school rulers (30cm) you would need to line up to match an otter's length.
If you had a toy car that is 18 cm long, would it be longer or shorter than an otter's depth?
