[[File:Calliactis and Dardanus 001.JPG|thumb|''Calliactis parasitica'' on the hermit crab ''Dardanus calidus'']] '''''Calliactis''''' is a genus of sea anemones. Species in this genus are mutually symbiotic with hermit crabs. The anemone gets a place to live and discarded scraps of the crab's food in exchange for its help in defending the crab.<ref>{{cite journal |author=Gusmão LC, Daly M |title=Evolution of sea anemones (Cnidaria: Actiniaria: Hormathiidae) symbiotic with hermit crabs |journal=Molecular Phylogenetics and Evolution |volume=56 |issue=3 |pages=868–77 | date=September 2010 |pmid=20457262 |doi=10.1016/j.ympev.2010.05.001}}</ref>
