Distributional notes
Results of studies carried out by O'Kelly et al. (2010) suggest that Ulva populations in tropical and subtropical regions consist of species that are largely unique to these areas, for which the application of names based on types from temperate and boreal European and North American waters is inappropriate. - (1 Sep 2010) - Wendy Guiry

General environment
This is a marine species.
