Flounder and Fluke are two types of flatfish, which belong to the same order of ray-finned fishes, Pleuronectiformes. Both types of fish live in salt water and can be found around the world in shallow coastal waters. Both species are highly sought after for their delicate, white flesh and are a popular addition to seafood restaurants. Despite their similarities, there are some distinct differences between these two types of fish.
Flounders are generally larger than Flukes, with the largest species measuring up to 80 cm in length. Their bodies are also much more compressed and they have a rounder shape than Flukes. The eyes of a flounder are typically situated on the same side of its body and its mouth is located on the underside. Flounders also have more prominent gill plates and longer, more slender fin rays than Flukes.
Flukes, on the other hand, are much smaller than Flounders, with the largest species measuring up to 40 cm in length. While their bodies are less compressed than Flounders, they have a more oval shape and their mouths are located on the sides of their heads. Flukes also have shorter fin rays and their eyes are located on opposite sides of their heads.
Flounders and Flukes are also distinguished by their diet and habitat. Flounders typically feed on crustaceans, worms and mollusks, while Flukes prefer to feed on smaller fish, such as anchovies and sardines. Flounders prefer to stay close to the seabed, while Flukes will often swim in the open waters of the ocean.
In conclusion, while Flounders and Flukes are both members of the same order of ray-finned fishes, they possess distinct differences in size, shape, diet and habitat. Flounders are generally larger, have more compressed bodies and feed on crustaceans and mollusks, while Flukes are smaller, have an oval shape and feed on smaller fish.
What is the Difference Between Flounder and Fluke?
Differences in Anatomy
Flounder and fluke are both types of flatfish. They are closely related and have a similar body shape and appearance. However, there are some key anatomical differences that can help to distinguish between the two. Flounder have smaller eyes, which are located on the same side of the head. Fluke have larger eyes and they are located on both sides of the head. Flounder have more rounded bodies and their fins are more curved than those of fluke. Fluke have a more elongated body and their fins are more pointed.
Habitat Differences
Flounder and fluke can both be found in marine habitats around the world. However, they prefer different types of environments. Flounder tend to inhabit shallow, inshore waters, such as estuaries, bays, and estuarine habitats. Fluke, on the other hand, prefer deeper waters, such as the open ocean and deep sea. Fluke are also more tolerant of colder temperatures than flounder, so they can be found in colder regions of the world.
Dietary Differences
Flounder and fluke both feed primarily on small invertebrates, such as shrimp, worms, and crabs. However, there are some key differences in their diets. Flounder tend to feed on smaller prey, such as plankton, while fluke prefer larger prey, such as fish and squid. Additionally, flounder tend to feed by lying on the seafloor and waiting for prey to come within reach, while fluke are active predators and will pursue their prey.
