Distribution. Mexico ( Hartman 1955; Green 1977 as Haliclona rubens ; Gómez & Green 1984; Green et al. 1986; Gómez 2002; Maas-Vargas 2004; González-Gándara et al. 2009; De la Cruz-Francisco & Bandala-Pérez 2016; current records), Bahamas, US (Florida), other countries in the Caribbean Sea; Brazil ( Muricy et al. 2011).

Remarks. Amphimedon compressa is a common inhabitant of the coral reefs in the GoM; it has been recorded in different coral reefs of Veracruz ( Green et al. 1986; Gómez 2007, 2011; González-Gándara et al. 2009), as well as in the Campeche Bank by Hartman (1955, as Haliclona rubens ). We observed this species frequently in different coral reefs at the Campeche Bank. A. compressa had also been reported by several authors, in the northern GoM ( Rützler et al. 2009) and off Quintana Roo ( Gómez 2002; Maas-Vargas 2004).
