LANDA-JAIME, Víctor et al. Mollusks associated to the coral reefs of Tenacatita, Jalisco, in the central Mexican Pacific. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.4, pp.1121-1136. ISSN 2007-8706.  https://doi.org/10.7550/rmb.32994.

An analysis of the most common species of mollusks of the coral reef of Tenacatita, Jalisco, in the central Mexican Pacific is presented. The study includes species found both in the reef structure as well as in the surroundings of bottom sand adjacent rocky intertidal zone. The systematic list comprises species of mollusks of the Gastropoda, Bivalvia, Polyplacophora and Cephalopoda classes making a total of 123 different species in 48 families, from which Calyptraeidae, Thaididae, Columbellidae, Conidae, Arcidae, Pteridae, Chamidae and Ischnochitonidae are the most representative. A series of ecological observations on the most conspicuous species and their affinity for the various types of habitat on the coral reef are made. A synthesis of all species that have had a change in nomenclature in the last 40 years is carried out. According to a review of the published literature, we found the species listed here are within their known geographic environment; however, they are new records for the study area. Finally, we carried out a comparative analysis between the species richness of the Tenacatita reef and that recorded in other locations of the Pacific coast with and without the presence of coral reefs.
