MORENO-ALCANTARA, María; GIRALDO, Alan  e  ACEVES-MEDINA, Gerardo. Heteropods (Gastropoda: Pterotracheoidea) identified along a coastal-oceanic transect in the Colombian Pacific. Bol. Invest. Mar. Cost. [online]. 2017, vol.46, n.2, pp.175-181. ISSN 0122-9761.  https://doi.org/10.25268/bimc.invemar.2017.46.2.733.

With the purpose of establishing the taxonomic composition of the heteropod assembly that inhabits the Colombian Pacific, zooplankton samples were collected in March 2014 along a coastal- offshore transect and later analyzed. Twelve species belonging to three families and three genera were identified. Atlanta lesuerii was the most abundant species in the study area. In addition, A. frontieri, A. oligogyra, A. inflata and A. plana were recorded for the first time in the South American Pacific, as well as A. helicinoidea in the Colombian Pacific. This work contributes in a significant way in the knowledge of the heteropod molluscs of the Colombian Pacific.
