Ecology of Xenobalanus globicipitis

Main Ref.	Toth-Brown, J. and A.A. Hohn, 2007
Remarks	Epibiotic (Ref. 111011). Commonly found attached to dorsal fins, pectoral flippers, and flukes of a variety of cetacean species; more abundant on hosts studied further from the shoreline (>2 km); associated as commensals (Ref. 96597); or may be termed as phoresy. Does feed on its host but filters plankton with its cirri (Ref. 96598). A suspension feeder. Peak seasonal abundance at water temperatures between 14° - 23° C. Undergoes self-fertilization and larvae is released in the water column where they develop and eventually settle unto a host. Life cycle reported at 5 to 6 months (Ref. 96597).
