“…Chiton articulatus is endemic to the Mexican Tropical Pacific, occurring from Oaxaca (16°N) to Sinaloa (23°N) (Ferreira 1983, Bullock 1988, Poutiers 1995, Reyes-Gomez 2003. It is a dominant grazer in the rocky intertidal shores (Poutiers 1995) and represents the main basibiont of several epibionts and endobionts (Alvarez-Cerrillo 2017). It may, therefore, generate microhabitats and probably plays a critical ecological role in increasing diversity and epibiotic relationships (Alvarez-Cerrillo 2017).…”

“…Chiton articulatus consumption has been promoted owing to its mineral contribution to the diet (Melo et al 2011). Formerly, Chiton articulatus represented an economic potential to become a coastal artisanal fishery (Poutiers 1995). However, the The food menu of some restaurants in Acapulco, Guerrero, including a dish with chiton, common name "Cucaracha/cockroach".…”

The marine mollusc, commonly called sea cockroach or chiton Chiton articulatus, is a mollusc belonging to the group known as Polyplacophora because its shell is composed of eight individual plates. This mollusc inhabits the rocky intertidal shore of the Mexican Tropical Pacific, where it is endemic. It has ecological, but also economic, importance. Ecologically, it is the preferred food of the snail Plicopurpura pansa, a protected species, in the cultural heritage of the country. Additionally, it is a basibiont (generates substrate for other individuals) that maintains the biodiversity of the Region. Economically, it has changed from artisanal consumption to become a culinary tourist attraction, offered at restaurants as an exotic and aphrodisiac dish, in tourist places like Huatulco or Acapulco. Despite being an exploited resource for decades, little is known about its life history. The Mexican Authorities have not yet recognised this mollusc as a fishing resource, so that it does not have any law that controls its extraction, sale and consumption, putting at risk the recruitment, survival and permanence of this species. The goal of this project is the preservation and support for the management of the species. The Project "Quiton del Pacifico Tropical Mexicano" seeks to provide the biological, ecological, reproductive, genetic, anatomical and morphometric bases of the populations of Chiton articulatus. The project was structured in four stages: 1) field sampling and obtaining samples, 2) disclosure and presentation of the project, 3) inclusion of students at the undergraduate and graduate level, 4) application of results. The inclusion and recognition of C. articulatus as a fishing resource will achieve impact at the national and regional level through the implementation of laws that regulate its fishing, as well as its inclusion in management and food security policies. Additionally, this Mexican Chiton Project is currently replicating with chiton species in Galapagos, Ecuador.

“…Since 2008, several studies have attempted to update the species inventory in the southern Gulf of Mexico reef with a special focus on cryptic and less charismatic taxa. This inventory is steadily increasing the knowledge of the region's species diversity of several groups such as fishes (Moreno-Mendoza et al, 2011;Robertson et al, 2016;Zarco-Perelló et al, 2014), crustaceans (Duarte et al, 2014;Escobar-Briones & Jiménez-Guadarrama et al, 2010;Paz-Ríos & Ardisson, 2013;Paz-Ríos et al, 2013a, b, 2018a, 2018bSantana-Moreno et al, 2013), echinoderms (Hernández-Díaz et al, 2013;Solís-Marín et al, 2015), cnidarians (González-Muñoz et al, 2013;Mendoza-Becerril et al, 2018), sponges (Ugalde et al, 2015) and mollusks (Ortigosa et al, 2013(Ortigosa et al, , 2015(Ortigosa et al, , 2018Reyes-Gómez et al, 2017;Sanvicente-Añorve et al, 2012).…”

“…En el Golfo de México, las investigaciones dirigidas a los poliplacóforos son escasas. Lyons & Moretzsohn (2009) proporcionaron una lista actualizada de las especies, Reyes-Gómez et al (2017) refirieron la fauna de quitones del Arrecife Alacranes, en tanto que Kaas (1993) y García-Ríos (2015) describieron sendas nuevas especies. El objetivo de este estudio fue analizar la estructura comunitaria de los quitones en una zona intermareal rocosa del sur del Golfo de México en 2 épocas contrastantes del año: secas (abril) y nortes (octubre) y proporcionar información sobre el crecimiento relativo de las especies dominantes en la comunidad.…”

The southern Gulf of Mexico is typically a coastal plain where rocky shores are scattered distributed. The goal of this study was to compare the chiton community structure of the rocky shore of Montepío during the dry and 'nortes' (stormy) weather periods, and to gather data on the relative growth of the dominant species. Sampling was carried out along a transect of 100 x 2 m in the intertidal zone and 83 individuals were collected. Six species were identified: Lepidochitona rosea, Chaetopleura apiculata, Ischnochiton kaasi, Lepidochitona pseudoliozonis, Lepidochitona liozonis and Acanthochitona andersoni. Species richness (S= 4) and Shannon diversity (1.36 and 1.29 bits ind-1 in dry and stormy seasons) were very similar between the 2 seasons; however, only 2 species occurred in both periods, suggesting a strong seasonal exchange of species (50%). This seasonal dynamics could be due to the discontinuity of the rocky substrate, which would not allow a rapid recovery of the populations after the impact of storms. Density of individuals was low (< 2.50 ind. 10 m-2) due to 2 factors: the diurnal tide, which induces the individuals to 12 h of air exposure, and the low salinity, due to the proximity of two rivers. The relative growth of the dominant species (L. rosea and C. apiculata) was isometric for the length vs. width relationship and negatively allometric for the length vs. height relationship. In the southern Gulf of Mexico, sites such as Montepío may function as marine oases for obligate inhabitants of hard substrates.
