Ecology Summary - Anoplodactylus petiolatus

Language:

Ecology of Anoplodactylus petiolatus

Main Ref.	Raiskii, A.K. and E.P. Turpaeva, 2006
Remarks	Bathymetrical range; intertidal to abyssal depths (Ref. 2015, page 216). Coastal to slope (Ref. 19). Epibiotic (Ref. 116112). Found on muddy substrate. A carnivore-scavenger (Ref. 96352). Feeds on hosts: Dynamena pumila. It seizes the stems of the hydroid using the apposition of the propodal sole spine and the terminal claws of the legs. Pieces are torn from the hydranth by the chelifores and transferred to the mouth where they are ingested (Ref. 12). Larvae frequently found on Obelia sp. and recorded as well in Clytia hemispherica (Ref. 121217). Feeds mostly at night, avoids touching the hydroid polyps, feeding mostly on the tips of spines (Ref. 121217). It so feeds on Syncoryne eximia (Ref. 12).
