High densities of the bivalve Mytella charruana were found for the fist time in the Bay of Cartagena, Colombian Caribbean, during an antifouling fild assay carried out during the second semester of 2008. This species reached average densities of 13400 individuals m-2 on underwater manmade substrates. Size range was between 0.5 and 3.6 cm with an average length of 1.95 cm.
