Chrysaora plocamia

Remarks: in Peru forming blooms and also massive numbers are stranded in huge aggregations found mainly in shallow waters, from subtidal line (8 – 10 m until 100 m depth), becoming less abundant towards offshore (Quiñones- Dávila 2008; Quiñones et al. 2015). Massive numbers of stranded medusae found in Patagonian coastal areas (Mianzan et al. 2005). Distribution in South America: medusa — Pacific Ocean, Peru to Chile, from 5 ° S to 55.015 ° S (Stiasny 1937; Morandini & Marques 2010; Bravo et al. 2011; Mianzan et al. 2014; Palma et al. 2011, 2014 b; Quiñones et al. 2015); Atlantic Ocean, Argentina, at 42 ° S along the Patagonian coastal waters (Mianzan & Cornelius 1999; Mianzan et al. 2005; Morandini & Marques 2010). Habitat: neritic, found in coastal and estuarine waters (Mianzan & Cornelius 1999). Dense aggregations at water surface observed in some Peruvian coastal areas, as Punta Salinas (11.2 ° S), Chilca (12.6 ° S), and Pisco (13.75 ° S) (Quiñones-Dávila 2008; Quiñones et al. 2015); Massive numbers of stranded medusae found in Patagonian coastal areas, where this species can cause mortality in salmon farming (Mianzan et al. 2005).
