Temporal and spatial distribution of organochlorine pesticides (OCPs) and the organophosphate pesticide chlorpyrifos, one of the main insecticides used in Argentina, was evaluated in two populations of the sea anemone Bunodosoma zamponii living under different anthropological stressors: Las Delicias (LD) adjacent to a wastewater plant, and Punta Cantera (PC) a reference site. Pesticides were analyzed […]

This present study describes for the first time the annual seasonality of a peculiar association between two different groups of cnidarians in temperate waters of the Southwestern Atlantic Ocean: the parasitic larval phase of the sea anemone Peachia sp. (Anthozoa) with the hydromedusa Liriope tetraphylla and Eucheilota ventricularis (Hydrozoa) from Mar del Plata, Argentina. As

Polychlorinated biphenyls (PCBs) are persistent and bioaccumulable organic compounds. The occurrence of PCBs was assessed in two populations of the intertidal sea anemone Bunodosoma zamponii living under different anthropogenic strains. One location was in vicinity to a wastewater plant (Las Delicias, LD), and the other was a preserved location chosen as a reference site (Punta

The diversity of Ceriantharia is known from studies formally describing species from the late 18th Century onwards. However, no nomenclators including a list and discussion of all valid species have been produced since a list discussed by Carlgren in 1912. The present nomenclator presents a complete list of adult species of Ceriantharia of the World, including a discussion on each

 In the systematics of cnidarians, the different types of cnidocysts are considered an important taxonomic character.In Hydra, the four types of cnidocysts found in the ectoderm, concentrated in tentacles and their measurements, together withother morphological and reproductive characteristics, are very important for the taxonomy of the species. In this study, weexplore in detail the biometric

As part of a biodiversity study on intertidal invertebrates, several sea anemones from the west coast of the Baja California Peninsula were collected in June 2016. The taxonomic features of four specimens agree well with those of the species Anthopleura radians, a recently described sea anemone from northern Chile. This study is the first published report

Anthopleura mariae sp. nov. is a new species of sea anemone (Actiniaria:Actiniidae) from the rocky intertidal of Punta Morro, Baja California, and PuntaEugenia Baja California Sur, México. This species is characterized by a columnwith verrucae arranged in longitudinal rows from margin to limbus with a redspot atop each verruca, as well as the presence of

The sea anemones diversity is still poorly studied in Isla del Coco National Park, CostaRica. Objective: To report for the first time the presence of the sea anemone Exaiptasia diaphana. Methods:Some rhodoliths were examined in situ in Punta Ulloa at 14 m depth, by SCUBA during the expedition UCRUNA-COCO-I to Isla del Coco National Park

In this study, we performed a bibliographical review examining the scientific literature on“feeding in Anthozoa” for the period from 1890 to 2019, using the scientific database Google Scholar,supplemented with additional literature. This study categorized published scientific papers on thistopic by decade of publication, target taxa, variability of species studied in each order and mainthemes studied.
