Abstract

Bryozoa (Cheilostomata, Ctenostomata, and Cyclostomata) in Galapagos Island fouling communities.

Abstract

Bryozoans have been infrequently studied in the Galapagos Islands, and even less so in nearshore biofouling assemblages. Based on surveys of Galapagos fouling communities in 2015 and 2016, we report 18 bryozoan species. At least 10 species are new records for the Galapagos, including Amathia sp. 1 (Bowerbankia group), Beania klugei Cook, 1968, Bugulina stolonifera (Ryland, 1960), Caulibugula cf. dendrograpta (Waters, 1913), Celleporaria inaudita Tilbrook, Hayward and Gordon, 2001, Hippopodina tahitiensis (Leca and d'Hondt, 1993), Nolella stipata Gosse, 1855, Schizoporella pungens (Canu and Bassler, 1928), Sundanella sp. and Watersipora subtorquata (d'Orbigny, 1852) sensu Vieira et al. 2014a. More than half of these are considered likely ship-borne introductions. Schizoporella pungens was the most abundant bryozoan. Continuing explorations of Galapagos biofouling communities will likely reveal additional introduced and native bryozoan species.
