BREVES, André  and  SKINNER, Luis Felipe. First record of the vermetid Petaloconchus varians (d’Orbigny, 1841) on floating marine debris at Ilha Grande, Rio de Janeiro, Brazil. RGCI [online]. 2014, vol.14, n.1, pp.159-161. ISSN 1646-8872.  https://doi.org/10.5894/rgci457.

This note aims to do the first record of the vermetid gastropod Petaloconchus varians rafting on floating marine debris. This record of the occurrence of the species at Ilha Grande (Rio de Janeiro, Brazil) is within its distribution range in the West Atlantic Ocean coast, however its distribution could be extended through antropogenic mechanisms. The dispersion of vermetids through floating debris should be investigated given the high potential of invasion by vermetids due to the increase in waste production.

Keywords : Bioinvasion; coastal zone; Gastropoda; rafting; Vermetidae.
