Hyperia
Hyperia is a genus of amphipod crustaceans belonging to the family Hyperiidae. These animals are commonly known as “whale lice” due to their association with large marine mammals.
Characteristics
Hyperia species are typically characterized by their elongated bodies, large eyes, and long, slender antennae. They lack a carapace, a feature common in other amphipods. Their bodies are laterally compressed, allowing for efficient swimming. They possess strong mandibles and a distinctive rostrum, a projection on the head.
Environment
Hyperia species are pelagic organisms, meaning they live in the open ocean. They are often found in association with large marine animals, particularly whales. Some species, such as Hyperia galba, are even known to be commensal, meaning they live on the bodies of their hosts, feeding on parasites or debris.
Common Names
Hyperia species are commonly referred to as "whale lice", a term often used to describe a variety of amphipods found on whales. Other common names include "hyperiid amphipods" and simply "hyperias".
