Abstract:

Introduction: The sipunculans are a group of marine invertebrates that have been little studied in the tropical eastern Pacific (TEP). Antillesoma antillarum is a species belonging to the monospecific family Antillesomatidae, considered widely distributed in tropical and subtropical localities across the globe. Objective: The main objective of this work was to examine the morphological and molecular differences between specimens from both coasts of tropical America to clarify the taxonomy of this species. Methods: We examined the morphology with material from the Mexican Caribbean and southern

In this paper the distribution of the dinoflagellate Spatulodinium pseudonoctiluca in different areas of the Mexican Pacific is depicted based on samples gathered during 2005-2010. This species is first recorded for Bahía de los Ángeles, Loreto and Bahía de Mazatlán in the Gulf of California, and in the southwest portion of the Mexican Pacific at Bahía de Acapulco, Guerrero and Salina Cruz, Oaxaca. This species appears in the study area mainly during the winter-spring period. The mature cells of S. pseudonoctiluca range from 100-173 μm in length and 89-120 μm in width. Cell size of the gymnodi

Sipuncula are marine unsegmented worms that can be found in benthic habitats, from shallow to deep-sea waters. In Mexico these worms have been scarcely studied. Among nine studies in the entire Mexican Pacific coasts, seven are from the central and northwestern Mexican Pacific. For over 80 years, only 24 species have been recorded. To improve the knowledge of the sipunculans from the central and northwestern Mexican Pacific, 501 specimens from three scientific collections of Mexico were revised. The specimens were collected by diverse methods from intertidal, subtidal, and bathyal depths (~100

The total number of species in Mexican oceans is 58, distributed among 19 genera and 10 families. All records were cross-referenced with the original literature, and those found to be questionable were deleted from the checklist. With the data reported in this checklist, an extrapolation of

During the analysis of phytal meiobenthic samples collected from a rocky-sandy beach in the state of Nayarit, in the Mexican Pacific, several specimens of harpacticoid copepods were obtained and taxonomically examined. These specimens were found to represent an undescribed species of the peltidiid genus <i>Peltidium </i>Philippi, 1839. The new species, <i>P. nayarit </i>sp. n. is described herein.

Abstract:

A list of 169 medusae species in 45 families recorded in Mexican waters is presented for the first time. 86 species (50.8%) were found in the Pacific Ocean, 75 species (44.3%) in the Gulf of Mexico, and 88 (52%) in the Mexican Caribbean Sea. Only 17 species (10%) were common to the three regions. The superclass Hydrozoa, the most diverse one, is represented by 151 species (89%), the Scyphozoa by 16 species (9.5%) and the Cubozoa by 3 (1.8%). Among the Hydrozoa, up to 6 new species have been described from Mexican waters. It is expected that the number of species will grow as surveys that inclu

Abstract:

For more than 10 years (2007-2018), the benthic macroinvertebrates of Bahía de Chamela (Mexican Pacific) were sampled at 31 sites (0-25 m depth). A total of 308 species of the five main classes of benthic molluscs were obtained (106 bivalves, 185 gastropods, 13 polyplacophorans, two scaphopods and two cephalopods). This is a significant increase in the number of species (246 new records) compared to the 62 species previously recorded more than 10 years ago. The distribution in the 31 localities of the bay is given for the first time for most of the species, together with information on its eco

Ecologically, it is the preferred food of the snail <i>Plicopurpura pansa</i>, a protected species, in the cultural heritage of the country.

Despite the efforts to monitor toxic and bioaccumulative persistent pollutants, they are still insufficient and outdated data from Mexican coasts, especially in polychlorinated biphenyls (PCBs) and polyaromatic hydrocarbons (PAHs), due to the number of aquatic bodies that have received little or no attention. In this regard, the Mexican Pacific's coastal zones and their aquatic ecosystems monitoring PCBs and PAHs in biota is critical because it allows us to estimate the potential r

The holotype of Porites baueri was collected in the Marías Islands in 1957, and described as a new species by Squires in 1959. Since then, this species was considered as endemic, which is due to the lack of other specimens or a review of the taxonomic characters until now.
