Hyale

Hyale is a genus of amphipod crustaceans in the order Amphipoda. It comprises several described species that occur primarily in marine environments.

Distribution and habitat: Hyale species have a wide geographic distribution, with records from temperate to tropical seas. They are typically benthic, living among sediments, algae, rocks, or crevices in shallow coastal zones and, in some cases, deeper offshore habitats. They often occur in microhabitats where they can find detritus, biofilms, and microalgae to feed on.

Morphology and ecology: Like other amphipods, Hyale species are small and laterally compressed, with a curved body and a segmented abdomen. They possess specialized appendages for locomotion and feeding, and their morphology is adapted to living close to substrates. Diets generally consist of detritus, algae, and minor organic matter, placing them in the detrital and grazing components of the benthic food web. Hyale individuals contribute to nutrient cycling in their habitats and serve as prey for fish and other invertebrates.

Taxonomy and research: The exact circumscription of Hyale has varied among authors, and placement within amphipod families has differed across classification systems. Ongoing morphological and molecular analyses have refined species boundaries and relationships within the genus. As with many small crustacean groups, taxonomic revisions and regional fauna studies continue to shape the understanding of Hyale’s diversity and distribution.
