This shrimp-like amphipod, named after the Andean word for 'darkness,' is the first large active predator found at such depths, highlighting the trench as a biodiversity hotspot. The discovery, part of the 2023 IDOS Expedition, underscores the importance of deep-sea exploration and offers insights into the unique adaptations of deep ocean life.

"Pom Pom Crab: Anemone Boxing Gloves for Crustaceans"

Scientists are still studying the relationship between the boxer crabs and the sea anemones to understand the benefits for both species.
