First report of the little-known scyphomedusa
Drymonema dalmatinum in the Caribbean Sea, with notes on its biology.
In summer periods, the medusae are very abundant, particularly in northern Chile (Iquique and Antofagasta), where the scyphomedusa
Chrysaora plocamia have a high impact on fisheries and tourism activities (Mianzan et al., 2014) and show predatory behavior over Engraulis ringens eggs and copepods (Riascos, 2014).
One Linuche mystery solved: all 3 stages of the coronate scyphomedusa
Linuche unguiculata cause seabather's eruption.
Specimens collected and observed in the area of the stings were identified as the scyphomedusa
Chrysaora lactea Eschscholtz, 1829 (Scyphozoa, Discomedusae, Pelagiidae) (Fig.
The inner sea of Chiloe is not an exception, where proliferations of the scyphomedusa
Chrysaora plocamia and Phacellophora catschatica have affected salmon farming installations (Palma et al., 2007; Bravo et al., 2011).
For example, abundant gelatinous organisms, such as the scyphomedusa
(Chrysaors quinquecirra) and the lobate ctenophore (Mnemiopsis leidyi), can be important predators on early-stage anchovy and competitors with juveniles and adults (Purcell et al., 1994), but their potential role with respect to bay anchovy recruitment could not be defined in our study.
(2006) reported that the scyphomedusa
Nausithoe punctata captured relatively few of the crustacean prey it encountered (adult copepods = 2% and nauplii = 12%).
Functional characteristics of nemalocysts found on the scyphomedusa
undulata, Modeeria rotunda and the scyphomedusa
Chrysaora plocamia were recorded for the first time for this geographical area.
