The large benthic mollusc Chiton articulatus, known locally as “sea cockroach”, is
commercialized among tourists and locals at Acapulco Bay for its muscular foot (ie, the …

An organism's body size is one of its most fundamental and observable traits for extant and
fossil taxa. In the present study, we document long-term evolutionary trends in body size of …

Non-indigenous species (NIS) have the potential to colonize and become established in a
wide range of coastal habitats. Species with broad environmental tolerances can quickly …

Body size is considered the most important trait in ecology, and as such, helps to understand
the species-environment interactions. We explored the relationship between body traits and …

Simple Summary Chitons are a charismatic group of mollusks that live underneath rocks on
shores throughout the world, where they experience variations due to environmental factors …

The edible chiton Chiton articulatus is a commercially important mollusk found in the rocky
intertidal zones of the Mexican tropical Pacific. Despite the intense harvesting in Acapulco …

Teratology is a congenital abnormality commonly observed in the shells of mollusks. A new
case of teratology in polyplacophorans is documented. This corresponds to a new case of …

The species Chiton echinatus was first described by Barmes in 1824. Subsequently, it has
been allocated to several widely distributed genera (eg, Acanthopleura, Enoplochiton …

Biotic interactions can determine species distributions and range limits, but little theoretical
background exists regarding variation in commensalistic associations across latitudes. We …

Here we present detailed morphological and molecular comparison of the Tonicia species
and ecotypes along Southeastern Pacific coast. Several specimens were examined by …
