Background. In Mexico, few studies have been carried out on epibiosis. Epizoic diatoms are used as biological
indicators of ecosystems due to their apparent epibiont specificity with host animals. Little is known
about this specificity in the planktonic larval phases. There have been no studies focused on epizoic diatoms
on the marine gastropod Ali...
The microstructure and nanostructure of nacre in Pteria colymbus were studied with high-resolution field emission scanning electron microscopy (FESEM). The tablets were found to be flat and polyhedral with four to eight sides, and lengths ranging from 0.6 to 3.0 µm. They consisted of nanocrystals 41 nm wide, growing in the same direction. X-ray dif...
Epibiosis occur frequently on the shells of some marine crustaceans, which often serve as substrate for various species of algae, there is few information on the associations between these. The objective of this study was to determine if the gastropod mollusk Aliger gigas (formerly Lobatus gigas) in larval had some sort of the association with alga...
The American oyster, Crassostrea virginica, is one of the most important economic
coastal fishery activities in Mexico. As for other bivalve molluscs, its sustainability is based on healthy
populations, and additional information on current reproductive cycles, will reinforce local management strategies.
The objective of this study was to evaluate...
Most of the inorganic biomineralized materials are deposited on an organic matrix that controls the orientation and structure of the crystals. It is thought that chemical groups at the surface of the matrix may act as a template for the nucleation and growth of the mineral. A x-ray diffraction study of the texturization development of the bivalve m...
The histology of the alimentary system of Strombus gigas was examined, focusing on the epithelial and subepithelial connective tissue of the mouth, style sac, digestive gland, and anus. Four structures were chosen because of their functions: (1) ingestion of food (mouth); (2) digestion, absorption, and storage of nutrients (style sac and digestive...
A histological study of Strombus gigas was analyzed with samples of the proboscis, eye antenna, foot, penis, anus, ctenidium, style sac and kidney. We observed five types of epithelial tissue: Simple columnar epithelium (foot, anus, ctenidium, kidney); pseudo-stratified epithelium (proboscis, eye antenna); glandular epithelium (foot, kidney), simpl...
El tegumento, compuesto por piel y sus apéndices, forma en conjunto un órgano que recubre el cuerpo, ofreciendo a los tejidos blandos subyacentes (dermis, hipodermis) una cubierta de protección contra lesiones. Además, participa en procesos de locomoción, de interacción física y química con el ambiente y de respiración. A fin de conocer la estructu...
The populations of Queen conch are overfishing, requiring the histological studies of its tissue, as the mprphological base to understand the functioning of this organism. The mantle is the responsible tissue to formation of the shell, to chemically and physically interacts with the environment, and it secretes mucus. This work describes the histol...
