The Saddleback Gunnel, scientifically known as Pholis ornata, is a species of fish belonging to the family Pholidae. This fish, commonly found in coastal waters, exhibits a distinctive saddle-like pattern on its body, contributing to its unique name.
Description & Characteristics
The Saddleback Gunnel is characterized by its elongated, eel-like body, reaching a maximum length of 30.0 cm. Its body is typically brown with dark saddle-like markings. It has a small mouth with protruding jaws and a prominent dorsal fin extending nearly the entire length of its back. The species Pholis ornata has a distinctive lateral line, a sensory organ that helps the fish detect vibrations and pressure changes in the water.
Habitat and Occurrence
The Saddleback Gunnel (Pholis ornata) thrives in a range of marine environments, predominantly within the subtidal, sublittoral, infralittoral, and deep zones of the oceans. Its habitat extends from the lower limit of the intertidal zone to the shelf edge, reaching depths of about 200 meters. This depth range places it firmly within the neritic zone, the area of the ocean that extends from the shoreline to the edge of the continental shelf. The species is common in these marine ecosystems, often inhabiting rocky reefs and kelp forests where it finds shelter and abundant food sources.
Taxonomy
The Saddleback Gunnel, Pholis ornata, belongs to the Class: Teleostei, Order: Perciformes, and Family: Pholidae. This taxonomic classification places it within a diverse group of bony fishes known for their well-developed fins and highly specialized features. The family Pholidae, commonly referred to as gunnels, is characterized by its elongated, snake-like body shape and its affinity for rocky marine environments.
Feeding
The Saddleback Gunnel, Pholis ornata, is a predatory fish. Its diet consists mainly of clams, crustaceans, and snails. These invertebrates are readily found within the rocky habitats where the fish resides, providing ample sustenance. The Pholis ornata uses its small, sharp teeth to capture and consume prey.
