Ecology of Periphylla periphylla
 
Main Ref. Migotto, A.E., A.C. Marques, A.C. Morandini and F.L. da Silveira, 2002
Remarks Found In deep waters (Ref. 116114). Symbiotic with amphipods, Hyperoche medusarum, Cyllopus magellanicus and juvenile Themisto guadichaudii (Ref. 3052), and has pycnogonids as an ectoparasite (Ref. 1943). Adults and juveniles of the pycnogonid Bathypallenopsis scoparia are found attached to this jellyfish (Ref. 121217). Exhibits vertical migration. Majority of the medusae moved from the deep basin to a zone below thermocline, a distance ranging from 100 to 400 m, at night. Move downward and disperse within water column below 200 to 350 m at dawn and during daylight hours, reside in narrow vertical intervals (about 60 m) in August and broader intervals (about 100 m) in December. Observed at water below thermocline at temperatures 6 to 8°C (Ref. 3051). Carcass and fresh samples used as bait of this species are scavenged by Myxine glutinosa, Munida tenuimana, Orchomenella obtusa, a decapod shrimp (Ref. 108800) and other unknown decapods (Ref. 108805).
