Sardina

Imagine a fish that's super small, about as long as your hand! That's a sardine. They have shiny, silver scales that sparkle in the sun. Sardines are super important because they are food for bigger animals like dolphins and seals. They also help keep the ocean clean by eating tiny plants and animals called plankton.

Sardines love to swim in oceans all around the world! You can find them in big groups called schools, especially in places like the Atlantic Ocean and the Mediterranean Sea. They like to stay near the coast where there's lots of food for them to munch on. Think of them as tiny ocean travelers, always looking for a tasty meal.

Sardines are super social! They swim together in massive groups, sometimes with thousands of fish! This helps keep them safe from hungry predators. When a big fish tries to catch one, the whole school can dart away in different directions, confusing the hunter. It's like a giant, shimmering underwater disco party!

What do sardines eat? They are plankton-eaters! Plankton are super tiny living things that float in the ocean. Some plankton are plants, and some are little animals. Sardines use their gills to filter these tiny snacks right out of the water as they swim. It’s like they have a built-in strainer for their food!
