Eusiridae

Eusiridae is a family of amphipods belonging to the order Amphipoda, which are small crustaceans. These amphipods are typically found in marine environments, inhabiting a variety of habitats from shallow coastal waters to the deep sea. They are characterized by their laterally compressed bodies and the presence of two pairs of antennae. The family Eusiridae contains numerous genera and species, many of which have specific ecological roles within their respective ecosystems. Their diet often consists of detritus and algae, contributing to nutrient cycling in the marine environment.

Eusirids are an important component of the benthic fauna, serving as a food source for larger marine organisms such as fish and invertebrates. Their distribution is widespread across the world's oceans. Research on Eusiridae contributes to our understanding of marine biodiversity and the ecological dynamics of different ocean habitats. Classification within the family relies on morphological features, particularly of the appendages and body segments. Ongoing taxonomic studies continue to refine the understanding of relationships within this diverse group of amphipods.
