Orinos

Orinos, also known as oar-fish, are a group of large, eel-like fish comprising the family Regalecidae. They are deep-sea dwellers, rarely observed by humans, and are characterized by their elongated bodies, often exceeding 10 meters in length, with some specimens reportedly reaching over 17 meters. Their bodies are covered in a silvery, scaleless skin and they possess a dorsal fin that runs the entire length of their body, often adorned with a crest of red filaments. The pectoral fins are small and fan-shaped, while the pelvic fins are elongated and ribbon-like, giving rise to their common name.

Orinos are believed to be solitary and pelagic, inhabiting depths ranging from the surface down to at least 1,000 meters. Their diet is thought to consist primarily of small crustaceans, squid, and possibly smaller fish, which they likely capture by filter-feeding or by actively pursuing prey. Reproduction details are scarce due to their elusive nature, but like other fish, they are presumed to lay eggs. Their rarity and the difficulty in studying them have led to many myths and legends, with sightings sometimes being interpreted as omens or sea monsters. Despite their size, orinos are considered harmless to humans. They are found in all of the world's oceans, but are most commonly reported in temperate and tropical waters.
