Hyalella azteca is a freshwater epibenthic amphipod of interest to ecotoxicology and evolutionary biology. It is the primary invertebrate crustacean used in the U.S. for sediment toxicity testing and have been the subject of recent gene expression studies in ecotoxicogenomics.

H. azteca is a species complex which has diverged in North America over the past 11 million years creating numerous ecotypes which are the subject of divergent and convergent evolutionary studies.

Genomic Resources

For the most current version of the assembly, please use 'NCBI BioProject' (find link below). If the assembly is unavailable in the BioProject page (it is still being worked on), you can look under the 'BCM-HGSC data' (find link below) for intermediate versions of the assembly.
