What remarkable new species were discovered in the deep ocean in 2024?

The answer

In 2024, researchers from the Schmidt Ocean Institute discovered over 100 new species during expeditions near Chile's seamounts, including bizarre gelatinous octopuses, translucent fish, and previously unknown coral species living at depths exceeding 4,500 meters. One standout was a ghostly white octopus found brooding eggs on manganese crusts at 3,100 meters depth. The Atacama Trench expeditions also revealed new amphipod species thriving under crushing pressures of over 600 atmospheres. These discoveries underscored how little we know about deep-sea biodiversity, with scientists estimating that over two-thirds of ocean species remain undescribed by science.
