Cassiopea andromeda (Forskål, 1775)

Remarks: species of the genus Cassiopea are hard to identify (Holland et al. 2004) due to similar morphology. The first Brazilian record refers only to the polyp stage and medusae reared in laboratory conditions (Migotto et al. 2002; Morandini et al. 2005a). Medusae were found in several places along the coast of Brazil, but mostly based on photographic records, precise identification of some of these populations still remains uncertain (Morandini et al.

2016).

Distribution in South America: polyp—Atlantic Ocean, south and southeastern coasts of Brazil (Migotto et al. 2002; Morandini et al. 2005a; Silveira & Morandini 2011; Morandini et al. in press); medusa—Atlantic Ocean, Cabo Frio, Rio de Janeiro, southeastern Brazil (Morandini et al. 2016).

Habitat: shallow water species (Morandini et al. 2005a).
