Dulcibella camanchaca is a species of amphipod crustacean discovered in the Atacama Trench, at depths of nearly 8,000 m (26,000 ft) in the South Pacific Ocean near Chile.[2][3] Measuring approximately 4 cm (1.6 in) in length, this predatory amphipod is adapted to the extreme conditions of the hadal zone, making it one of the deepest-living predators identified to date.[4][5]

Taxonomy

[edit]

Dulcibella camanchaca belongs to the family Eusiridae and was formally described in 2024 by marine biologists Johanna Weston and Carolina Gonzále.[6][7] The genus name, Dulcibella, is derived from Dulcinea, a character in Don Quixote, consistent with a tradition of naming amphipods after literary figures.[8] The species epithet, camanchaca, originates from an Andean word meaning "darkness," referencing its deep-sea habitat.[9][10]

Discovery

[edit]

The species was discovered during a 2023 oceanographic expedition that investigated the biodiversity of the Atacama Trench.[11] The research team used advanced deep-sea exploration equipment to collect specimens from depths nearing 8,000 meters.[12] The identification of D. camanchaca as a new species was confirmed through DNA analysis and detailed morphological examination.[13]

This discovery has contributed to the growing recognition of the Atacama Trench as a region of high biodiversity and endemism.[14]

Morphology and behavior

[edit]

Dulcibella camanchaca is larger than most amphipods found at similar depths.[15] It exhibits predatory behavior, utilizing specialized appendages to capture and consume smaller crustaceans.[16] These adaptations suggest an ecological role as an active predator in the hadal zone.[17][18]

Significance

[edit]

The identification of D. camanchaca highlights the ecological importance of the Atacama Trench and the potential for further discoveries in deep-sea environments.[19] Continued exploration of these regions may yield insights into the adaptations and biodiversity of organisms living in extreme conditions.[20]
