Mobile macrofauna and community structure were studied at the Youngjong tiny tidepools, Incheon, Korea. Samples were monthly collected from February 2010 to January 2011. Mobile macrofauna community comprised a total of 18 species, including 1,122 individuals and 623.6 gWWt. The dominant species were Luciogobius guttatus, Tridentiger bifasciatus, Hemigrapsus penicillatus, Pagurus minutus. The number of species and biomass were low from December to March, and high from April to November. Canonical correspondence analysis revealed that temperature were the most important environmental variables in determining the observed variability in community composition. Species diversity indices ranged from 0.14 to 2.05, and showed the highest value in October 2010. The tide pools provide spawning ground and nursery ground for some fishes and decapods.
