Pelaya: A Fascinating Elongated and Compressed Fish
La pelaya, scientifically known as Zeugopterus regius, belongs to the class of the Actinopterygii, more commonly identified as ray-finned fish. This peculiar fish, characteristic of coastal waters, represents a fascinating adaptation to the marine environment where it lives. Although it is not among the most popular species on the commercial market, its the habitat, features physical and behavior deserve to be fully highlighted.
Morphological characteristics of the Pelaya
The pelaya has a head with a marked groove located in front of the upper eye. Its eyes are one of its most notable features, as they are close together but separated by a prominent reddish bony ridge. The lower eye It is positioned in front of the upper one, giving this fish a unique anatomy.

Another distinctive feature is its flat body, which allows it to remain half-buried in mud or camouflaged among the rocks and sand of the seabed. The scales on the ocular side have cutaneous appendages that may be branched. dorsal fin, which begins in front of the eyes, has a longer and more prominent first ray. The caudal fin is rounded, while its Coloration varies between brown tones with dark spots distributed throughout the body.
A Typical Size and Comparative Context
The pelayas do not usually exceed the 20 centimeters in length, which categorizes them as small fish compared to other flat species such as the sole or turbotHowever, these species share a interesting evolutionary process: When they are fry, their body is symmetrical and they have one eye on each side. During their development, one of the eyes migrates to the opposite side, turning them into asymmetrical flatfish we know.
Habitat and Behavior
The pelaya lives mainly in rocky, sandy bottoms and muddy shallow waters. Its camouflage ability is exceptional. This fish can semi-bury itself to the point that only its eyes are visible, which helps it stalk its prey. Its diet includes crustaceans, molluscs and other small marine organisms that venture near their hiding place.

In addition, its ability to remain motionless and camouflaged protects it from predators natural, representing a crucial evolutionary strategy for survival in their environment. This behavior makes it a fascinating species for the study of evolutionary adaptations.
Similar Species: Zeugopterus Punctatus
A species similar to the pelaya is the Zeugopterus punctatus, which is also common in the same waters and shares morphological characteristics. However, each has distinctive spot patterns and colours, which allows them to be differentiated upon closer inspection. Both species belong to the Scophthalmid family and the Pleuronectiformes order.
Relationship with Humans and Ecosystems
Although the pelaya is not a species of great commercial interest, it plays an important role in the food chain of their habitat by controlling populations of small crustaceans and mollusks. In addition, their ability to camouflage themselves and survive in complex substrates makes them an important asset for marine ecosystems.

Researchers and ecologists find the pelaya of great interest due to its behavior and evolutionary adaptations that shed light on biodiversity in the seabed. With growing concern about the effects of climate change on these habitats, the pelaya can be a crucial biological indicator to assess the health of coastal ecosystems.
The pelaya exemplifies how certain marine species have developed physical and behavioral characteristics to thrive in their natural environment. From its flat body to its ability to blend in with the seafloor, this species is a testament to the ingenuity of evolution.
Exploring and protecting habitats where the pelaya resides is essential to preserving these unique marine jewels. With conservation initiatives and increased awareness of the richness of marine ecosystems, the pelaya can continue to be a key piece in the great puzzle of marine biodiversity.
