Bryocyclops

Bryocyclops is a genus of freshwater-dwelling cyclopoid copepods. The prefix Bryo- for Bryophyta (Mosses) refers to the fact that the first few species were described from mosses.

== Distribution == Species belonging to this genus are distributed in all major biogeographic realms except Antarctica, although there are only a handful of species from the Nearctic (B. muscicola) and Neotropical realm (B. campaneri and B. rochi). Researchers suspect that with increasing sampling efforts, more species will be discovered from these regions. Apart from continental habitats, some species occur on the oceanic islands of Guam, Fiji, Tonga, Samoa and Christmas Island. In recent years, five new species have been described from caves in Thailand.
