Starfish Superpowers
Starfish are amazing ocean animals. They are known for their special ability called regeneration. If a starfish loses an arm, maybe from a predator, it can grow a new one back! Sometimes, a lost arm can even grow into a whole new starfish if it has a piece of the central body. This ability helps them survive and thrive in the ocean.
If you could have a superpower like a starfish, what would it be and why?

Read the size clue
Imagine holding a starfish in your hands. It is usually about 250 millimeters wide, which is the same as 25 centimeters. This is about as wide as your hand stretched out from your thumb to your pinky finger! A starfish is also quite flat, only about 10 millimeters, or 1 centimeter, deep. This is like the thickness of a small coin or a few stacked credit cards. They spread out wide but don't take up much vertical space.
Quick Check
How many centimeters wide is a starfish?
Estimate
Find something in the room that is about 25 cm long. What is it?
