Halibut vs Fluke: What's the difference?

Fluke and halibut are both flatfish, but they are different species with very distinct characteristics! Here are some differences between the two:

  1. Appearance: Fluke have a more elongated and slender body compared to the broader and rounder body of halibut. Fluke also have a distinct curve in their lateral line, while halibut have a straighter lateral line.
  2. Size: Halibut are typically much larger than fluke. The Atlantic halibut can grow up to 700 pounds, while fluke usually range from 1-3 pounds.
  3. Habitat: Halibut are typically found in deeper waters, while fluke prefer shallower waters closer to shore.
  4. Taste: Halibut have a firmer and meatier texture compared to the more delicate and flaky texture of fluke. Halibut also has a more distinct flavor, while fluke has a milder taste.

Overall, while both fluke and halibut are flatfish with some similarities in appearance, they are distinct species with differences in size, habitat, and taste.



Pacific halibut (Hippoglossus stenolepis) and Atlantic halibut (Hippoglossus hippoglossus) are different species of halibut that have some differences in appearance, habitat, and distribution.

Pacific halibut are found along the North American coast from California to Alaska and into Russian waters. They have a more slender body compared to the Atlantic halibut and typically weigh between 20-80 pounds. Pacific halibut are also known for their sweet and delicate flavor.

They have a broader and more rounded body shape compared to the Pacific halibut and can grow much larger, with some individuals weighing over 700 pounds.

While both species are flatfish and belong to the same family, they are distinct species with differences in appearance, habitat, and taste.
