Some animals use special tools inside their bodies to find their way across the big blue ocean, just like you use a map to find your favorite toy in a store.
Like a compass, some fish have a kind of built-in map that helps them know which direction they're going. It's like having a little arrow pointing north in your head! This helps them travel long distances even when the water is dark and there are no landmarks to see.
Using the Sun and Stars
Some animals, like sea turtles, use the sun during the day and the stars at night to guide them. It's like using a flashlight to find the way home after playing hide-and-seek in the dark, they just follow the light from above!
Following the Currents
Other animals, like some types of fish and whales, use the ocean currents, which are like giant rivers moving through the sea. They let the current carry them along, like floating on a stream while you're playing with your rubber duck in the bathtub.
These tools help animals travel across the ocean without getting lost, just like how you find your way around your house every day!
