'Eurythenes atacamensis', a crustacean related to shrimp, was found scavenging in the Atacama Trench off the coasts of Peru and Chile.

It is an amphipod, a type of crustacean closely related to a shrimp, endemic to the Peru-Chile Trench (also known as the Atacama Trench). Measuring more than 8 cm (3.14 inches) in length, it is nearly twice the size of its nearest relative, making it a giant. Spanning an extensive vertical range, juveniles and adults can be found in the trench between 4,974 to 8,081 metres (15.700 to 26.512 feet). This includes the deepest point, known as Richard’s Deep.

As a scavenger, this amphipod plays a critical role within the food web by intercepting and redistributing food sinking down from above. They quickly detect and consume new carrion, like the mackerel bait we used to coax individuals into the trap.

'Eurythenes atacamensis' is a member of a well-studied deep-sea genus ('Eurythenes'), which is notorious for what is known as cryptic speciation. In other words, when it is hard to visually tell one species from another.
