Distributional notes
Ostreopsis cf. ovata: Adriatic Sea; Tyrrhenian Sea; Brazil; Ligurian Sea; Balearic Sea; Thailand; Ecuador; Indonesia; Korea; Reunion Island: Japan (Carnicer et al., 2016, citing various authors). - (18 Nov 2016) - Wendy Guiry

Usage notes
Producer of a toxic butanol-soluble compound, perhaps a palytoxin analogue, as in some other species of Ostreopsis. Faust & Gulledge (2002: 51) notes that this species produces an unnamed toxin. An epiphytic toxic dinoflagellate (Monti & Cecchin, 2012 citing Ciminiello et al., 2006: 2008: Guerrini, 2010).Ostreopsis is a benthic and epiphytic dinoflagellate known to produce palytoxin-like compounds (Penna et al. 2012). Harmful species (Lassus et al. 2017).

General environment
This is a marine species.
