Pleuronichthys verticalis, commonly known as the vertical flounder, is a species of flatfish found in the marine waters of the Pacific Ocean. It is a relatively small fish, reaching a maximum size of 37.0 centimeters in length. Pleuronichthys verticalis is an important part of the marine ecosystem, contributing to the balance of the food web.
Description & Characteristics
Pleuronichthys verticalis, like other flatfishes, is characterized by its flattened body shape and both eyes located on one side of its head. The species can be identified by its relatively large, oval-shaped eyes, its somewhat elongated body shape, and its smooth, scaleless skin. The dorsal fin runs the length of its back, and the anal fin is long as well. Pleuronichthys verticalis can be distinguished from other flounders by its unique coloration, which ranges from a light brown or gray to a reddish brown, sometimes with dark blotches or spots.
Habitat and Occurrence
Pleuronichthys verticalis is a demersal fish, meaning it lives on or near the bottom of the ocean floor. This species is found in a wide range of depths, from 9.0 to 200.0 meters, and is commonly found in the neritic zone, which extends from the shoreline to the edge of the continental shelf. Pleuronichthys verticalis can be observed in a variety of habitats, including sandy bottoms, rocky reefs, and kelp forests.
Taxonomy
The species Pleuronichthys verticalis belongs to the Class: Teleostei, Order: Pleuronectiformes, and Family: Pleuronectidae. This family, also known as the right-eyed flounders, includes a wide variety of flatfish species found throughout the world’s oceans.
Feeding
Pleuronichthys verticalis is a carnivore, and its diet primarily consists of small invertebrates such as crustaceans, worms, and mollusks. They use their flattened bodies to lie in wait on the ocean floor, ambushing prey as it swims by. Their camouflage coloration allows them to blend seamlessly with their surroundings, making it difficult for their prey to spot them.
