The Association of Hydractiniid Hydroids and Hermit Crabs, with New Observations from North Florida

  • Claudia E. Mills


The hydrozoan family Hydractiniidae, composed of the genera Hydractinia, Podocoryne, and Stylactis, has a cosmopolitan distribution. Hydractiniids are often found in association with other marine animals; perhaps the most common association involves hydractiniid polyps colonizing shells occupied by hermit crabs. The hydroidhermit crab association is not obligatory for either animal; both the polyps and the hermit crabs are also found freeliving or on other available substrates.
