Sandstone intertidal reefs of Bahia, Brazil. Low intertidal zone with biogenic reefs built by vermetid gastropods and red calcareous algae. Definitely an important nursery ground for fish and crustaceans.

Today’s special highlight for the reefs built by polychaete (Phragmatopoma caudata) around the #tidepools

Another cloudy day…another intertidal flat reef…awesome species-rich #tidepools

This morning was cloudy, but #tidepools#rockpool#tropical
