Trichocorixa
water boatmen
Trichocorixa is a genus of water boatmen in the family Corixidae comprising approximately 14 described species. Members of this genus are notable for their exceptional tolerance of saline and hypersaline habitats, ranging from brackish coastal marshes to salt ponds with salinities exceeding 150‰. Several species have become invasive outside their native ranges, with documented ecological impacts through predation on brine shrimp and other zooplankton. The genus exhibits complex life history adaptations including staggered egg hatching, salinity-dependent embryonic development, and overwintering strategies that vary among species and populations.
