Order: Amphipoda
Family: Eusiridae
Genus: Dulcibella

Binomial name
Dulcibella camanchaca
Weston & González, 2024

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. 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.

Taxonomy

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

Discovery

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

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

Morphology and behavior

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

Significance

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