As the largest flatfish in the world, the Atlantic Halibut is a deep-sea giant that can grow up to a staggering 15 feet long and weigh more than 700 pounds. But there's more to this fascinating fish than just its size.

In this article, learn why it’s a prized catch for seafood lovers. We’ll discuss its physical characteristics, habitat, nutrition, and more.

What is Atlantic Halibut?

The Atlantic halibut is a large flatfish native to the North Atlantic Ocean that belongs to the family Pleuronectidae and is recognized as one of the largest teleost fish in the world.

Known for their flat, pancake-like shape, these fish have a unique twist: both of their eyes end up on the same side of their body, which helps them blend in with the ocean floor as they hunt for food.

Halibut are not only fascinating to look at but also valued for their delicious, mild flavor.

Physical Characteristics of Atlantic Halibut

The Atlantic halibut has a distinctive flat, asymmetrical body that can grow to impressive sizes, reaching lengths of up to 15 feet long. Its upper side is typically dark brown to olive, which serves as a camouflage against the ocean floor, while its underside is pale.

It has a large, wide mouth filled with sharp, needle-like teeth that help it snatch up prey with ease. Its skin, while smooth to the touch, has a slightly rough texture that feels like fine sandpaper—perfect for gliding along the ocean floor!

Atlantic Halibut Habitat

Atlantic halibut live on or close to the sea floor, especially in areas with sand, gravel, or clay. They’re comfortable at a range of depths, from shallow waters around 50 meters deep to much deeper spots reaching 2,000 meters. Found throughout the North Atlantic, these fish thrive in cold environments.

Atlantic Halibut Nutrition

Atlantic halibut is not just tasty; it's also packed with nutrients that make it a great choice for anyone looking to eat healthily.

This fish is low in fat and full of high-quality protein, which helps build and repair muscles. It's rich in omega-3 fatty acids, like EPA and DHA, which are good for your heart and help reduce inflammation throughout the body.

On top of that, halibut is a good source of important vitamins and minerals such as vitamin D, which supports bone health; vitamin B12, which helps with energy levels; selenium, which has antioxidant properties; and magnesium, which supports various bodily functions.

Whether you're watching your weight or just aiming to eat better, including Atlantic halibut in your diet can boost your health.
