Dead corals and limestone boulders that act as substrate for live specimens of marine invertebrates and algae are sold as ‘live rock’ in the international aquarium trade. During a customs inspection of an airfreight shipment of ‘live rock’ at Schiphol Airport (Netherlands), 450 boulders imported from Indonesia were checked for the presence of undeclared organisms. During unpacking, about 50% of the boulders appeared to have small stony corals attached to them. Some of these corals belonged to a species unknown from Indonesia. Mitochondrial COI and nuclear ITS markers revealed 100% and 99.3% match with Polycyathus chaishanensis Lin et al., 2012, a species reported from tidal pools in Taiwan. This new distribution record suggests that despite their easy access, intertidal and shallow subtidal reef coral assemblages (< 1 m depth) may still be underexplored.
