An expedition leader has captured rare footage of an oarfish swimming near the ocean’s surface, offering an unusual glimpse of a mysterious deep-sea species that humans rarely encounter alive.
Earlier this year, expedition leader Isabelle Nelson Morales was leading an ocean safari when she spotted something unusual in the water. The enormous, silvery animal initially left her and the passengers unsure what they were seeing before the boat’s captain identified it as an oarfish, a species normally found hundreds or thousands of feet beneath the surface.
Oarfish typically inhabit depths of around 600 to 3,000 feet, making sightings at the surface extremely uncommon. Nelson Morales said the fish swam in circles, occasionally disappearing into deeper water before returning to the surface.
The animal appeared calm enough that Nelson Morales and other passengers entered the water to observe it from a respectful distance. She said the oarfish repeatedly swam toward them, forcing them to move out of its path.
The encounter also gave Nelson Morales an opportunity to learn more about a species she had never expected to see. Oarfish are the longest bony fish in the world, with some reaching approximately 26 feet in length. The individual she encountered was estimated to be between 13 and 16 feet long.
The species has also developed a reputation in Japanese folklore as a “doomsday fish.” According to traditional beliefs, sightings of oarfish can precede earthquakes or tsunamis. However, there is no established scientific evidence that the animals can predict natural disasters.
Nelson Morales said she viewed the encounter as a fortunate experience rather than an ominous sign. Researchers also know relatively little about the behavior of oarfish because they spend most of their lives in deep water, far from human observation.
Surface sightings can sometimes indicate that an oarfish is ill, injured or nearing the end of its life, making observations of healthy animals particularly valuable. The footage therefore provides a rare opportunity to observe the species alive and swimming in its natural environment near the surface.
Despite their unusual appearance, oarfish are not considered dangerous to humans. Their shimmering bodies, elongated shape and distinctive fins make them one of the ocean’s most striking deep-sea animals.
