Ecological and population characteristics of the seashell Conus princeps on the Pacific coast of central Mexico

Marine snails of the genus Conus have acquired remarkable biomedical importance because of the high number of toxins they produce for feeding and self-defense. One of these toxins gave way to a new medication and two other are under development for clinical and cosmetic purposes. Nevertheless, there...

description Marine snails of the genus Conus have acquired remarkable biomedical importance because of the high number of toxins they produce for feeding and self-defense. One of these toxins gave way to a new medication and two other are under development for clinical and cosmetic purposes. Nevertheless, there is little basic knowledge about this group of species, particularly in Mexico. This study aimed to determine the relative abundance, spatial distribution, bathymetric distribution, and habitat preference of the snail Conus princeps along the southern coast of Jalisco (Mexico). To achieve this goal, we conducted direct samplings by snorkeling or scuba diving at 13 beaches, covering the intertidal, shallow subtidal, and deep subtidal zones. Relative density was between 0.021 and 0.418 snails per 100 m2, with an average value of 0.152 snails per 100 m2. The population showed an aggregated spatial distribution pattern according to the nearest neighbor index. Snails had shells that measured between 23.1 mm and 52.2 mm long, with an average shell size of 39.7 mm. Conus princeps was mainly distributed in the intertidal and shallow subtidal zones. The smaller organisms were present at shallower depths, while the larger organisms were distributed throughout the sampled depth habitats. In general, snail abundance decreased as depth increased. From the underwater photography analysis, we determined that Conus princeps snails prefer rocky bottom habitats covered with brown seaweed.

Los caracoles marinos del género Conus han adquirido notable importancia biomédica por el elevado número de toxinas que producen para su alimentación y defensa, de las cuales una ha dado lugar a un nuevo fármaco y otras más se encuentran en desarrollo para aplicaciones clínicas y cosméticas. No obstante, es poco el conocimiento básico que se tiene sobre este grupo de especies, en particular en México. Con este trabajo se busca determinar la abundancia relativa, distribución espacial, distribución batimétrica y preferencia por el sustrato del caracol Conus princeps a lo largo de la costa de Jalisco (México). Para ello, se realizaron búsquedas directas por medio de buceo libre o autónomo en 13 playas cubriendo los estratos del intermareal, submareal somero y submareal profundo. La densidad relativa presentó valores de entre 0.021 y 0.418 caracoles por 100 m2 y un promedio de 0.152 caracoles por 100 m2. La población presentó una distribución espacial de tipo agregada según los análisis del índice del vecino más cercano. Se presentaron caracoles con conchas de entre los 23.1 mm y 52.2 mm de largo, con un promedio de 39.7 mm. Conus princeps se distribuyó principalmente en los estratos del intermareal y submareal somero. Los organismos de tallas menores se presentaron a bajas profundidades, mientras que los organismos de tallas mayores se distribuyeron en todo el estrato de profundidad muestreado. En general, se observó que con el aumento de la profundidad, disminuyó la abundancia de los caracoles. A partir del análisis de fotografías submarinas, se determinó que existe una preferencia de los caracoles C. princeps por habitar en sustrato rocoso cubierto de algas pardas.
