Red mangrove (Rhizophora mangle) hanging roots are the primary solid substrata along mangrove channels at Twin Cays and their vertical orientation assures optimal protection from silting. Sponges and ascidians make up most of the biomass of epibionts. Sponges shown include Lissodendoryx cf. isodictyalis (bluish gray), Tedania ignis (orange massive), Scopalina ruetzleri (orange encrusting), and Haliclona manglaris (turquoise); the ascidians are Distaplia corolla (deep orange knobby structures), which also overgrow sponges.
