Imagine you have three friends helping you carry your backpack, but only two can help at the same time. That's like having three hearts, two work while you're moving, and one takes a break until you stop. Octopuses are like that! They need all their energy to swim, so they save one heart for when they’re resting.
Examples
- A baby octopus uses its three hearts to swim around the coral reef.
- An octopus takes a nap and lets one heart rest while the others work.
- The octopus runs away from a crab, using two of its hearts to keep moving.
