Sharks Make Friends and Help Our Ocean Environment

Scientists at the University of Exeter in England made an amazing discovery about sharks. These ocean animals form friendships with each other, just like we do with our neighbors and family.

For six years, researchers watched 184 bull sharks in Fiji. They found that sharks pick certain friends to swim with and return to the same spots together. Male sharks, who are smaller than females, gain safety by staying close to their shark friends. This helps them avoid fights with bigger sharks.

Sharks also play a huge role in keeping our oceans healthy. As they swim up and down in the water, they mix nutrients from deep areas with surface water. This helps tiny ocean plants called phytoplankton grow. These plants take carbon dioxide from the air and make oxygen for all of us to breathe. Even shark waste helps feed ocean ecosystems and stores carbon on the ocean floor.

The facts about shark safety might surprise our community. In 2024, only 47 people worldwide were hurt in shark attacks - the lowest number in almost 30 years. Sharks have lived in our oceans for 450 million years, surviving longer than dinosaurs and trees.

This research helps us understand that sharks are smart, social animals that keep our planet's oceans working well. Learning more about their friendships and environmental role can help our community support ocean conservation efforts.
