Asellota
Asellotes
Asellota is a suborder of isopod crustaceans comprising approximately one-quarter of all marine isopods. The group exhibits remarkable ecological diversity, occurring in marine, freshwater, and subterranean habitats from shallow coastal waters to abyssal depths, including hydrothermal vents. Members possess distinctive morphological specializations including a complex copulatory apparatus that distinguishes them from other isopods. The suborder has undergone multiple independent colonizations of deep-sea environments, with some lineages showing extensive radiation in these habitats.
Calliopiidae
Calliopiidae is a family of hyperbenthic amphipods distributed across the North Atlantic and North Pacific oceans. Members inhabit diverse marine environments including subtidal waters, hydrothermal vents, and the hyperbenthic zone immediately above the seafloor. The family includes the newly described genus Bathya from deep-sea hydrothermal vents and Calliopius species associated with macroalgae.
