摘要：A list of the marine invertebrate species identified until now from the rocky intertidal shore at Montepío,Veracruz, is presented. The information was obtained from 10 years of collections made by the Colección Nacionalde Crustáceos and additional records were compiled from published information. The species list includes the lifeform in relation to the substrate, epifauna or criptofauna, as well as its type of distribution considering the 2 mainzoogeographic provinces recognized for the Gulf of Mexico: Carolinean and Caribbean; the species found only in theGulf of Mexico are also noted. The list includes 195 species belonging to 9 groups of which Crustacea is the mostdiverse with 73 species, followed by Mollusca with 69 and Echinodermata with 18; the less diverse groups wereChelicerata with 2 species and Platyhelminthes and Sipuncula with 1 species each. Seventy-four species represent newlocality records and 7 are new records for Veracruz. A total of 5 517 invertebrate species have been reported for theMexican portion of the Gulf of Mexico, thus 3.5% of this total can be found in Montepio. More species were part ofthe epifauna (70%) than the criptofauna (30%) which is composed mainly by molluscs, polychaetes and sipunculids.A larger tropical affinity was observed in the obtained species composition; however, an important number of speciesare more subtropical or Carolinean (86) and 51 species occur only in the Gulf of Mexico.
