Overview
The flounder is a truly unique fish that lives in oceans all around the world. These flat fish have a funny party trick: they can change color to blend in with their surroundings, making them masters of disguise in the underwater world!
Flounders have an interesting body shape that helps them hide on the ocean floor. They can grow up to 0.9 meters (3 feet) long, but their flattened bodies let them rest almost invisibly on sandy or muddy bottoms.
Flounders belong to the scientific class Actinopterygii. This class includes fish that have bony skeletons, making them different from sharks, which have cartilaginous bodies.
As fierce underwater predators, flounders enjoy a diet of small fish, squid, and crustaceans. Using their impressive camouflage skills, they wait patiently for dinner to swim by before launching a surprise attack!
Flounders also have a fascinating growth story. They start their lives swimming upright, but as they grow, one eye shifts to the other side of their body, allowing them to become fully flat and ready to blend in with the ocean floor.
These fish can live up to ten years, making them seasoned veterans of the sea. With a little bit of patience and lots of curiosity, you can learn more about these incredible creatures and their underwater adventures!
