Rare Giant Phantom Jellyfish Sighted Off Argentina Coast Amidst New Discoveries

Scientists from the Schmidt Ocean Institute have documented a rare giant phantom jellyfish (Stygiomedusa gigantea) in the deep waters off the coast of Argentina. This observation was made during an expedition that also led to the identification of numerous potential new species and significant coral reef systems.

Rare Sighting Details

The giant phantom jellyfish was filmed by a remotely operated vehicle (ROV) at a depth of 250 meters (approximately 820 feet) below the surface in the South Atlantic Ocean. The sighting occurred along the Colorado-Rawson submarine canyon wall.

The Elusive Giant Phantom Jellyfish (Stygiomedusa gigantea)

Stygiomedusa gigantea is a rare deep-sea species known for its considerable size. Its bell can measure up to 1 meter (3.3 feet) in diameter, with its four ribbon-like oral arms extending up to 10 meters (33 feet) in length. These long, pink arms are used to capture prey such as plankton and small fish, guiding them toward the mouth, and are not stinging tentacles.

This species is considered exceptionally rare, with approximately 118 documented sightings over 110 years. It is believed to inhabit all oceans except the Arctic, residing at depths that can reach up to 22,000 feet.

Broader Expedition Discoveries

During the same expedition, the Schmidt Ocean Institute team reported identifying 28 suspected new species.

Potential New Species Identified

These potential new species include various forms of marine life such as worms, anemones, corals, and sea urchins.

Significant Coral Reef Systems Uncovered

Furthermore, the expedition revealed several extensive reef systems. Among these discoveries was the world's largest known Bathelia candida coral reef. Dr. Melisa Fernández Severini of Instituto Argentino de Oceanografía and CONICET stated that the collected samples would be valuable for future research into the connections within these marine ecosystems.
