Halibut

Interesting facts

Halibut are the biggest flatfish in the entire ocean!

Some halibut migrate thousands of miles across the deep ocean.

Their name means "holy flatfish" because they were often eaten on holy days.

They can live to be over 50 years old, often in chilly waters!

Special abilities

Halibut can change their skin color and pattern to perfectly match the ocean floor, helping them hide from predators and prey.

Young halibut start with eyes on both sides, but one eye gradually moves to the top as they grow and flatten.

Halibut lie perfectly still on the seabed, using their flat bodies to ambush unsuspecting fish that swim too close.
