This paper provides the first photographs of live specimens and a re-description of the poorly known sea anemone Condylanthus magellanicus Carlgren, 1899. Condylanthus comprises only two species, C. magellanicus and C. aucklandicus Carlgren, 1924, which are considered probable synonyms by some authors. Since its original description, C. magellanicu...
Based on a phylogenetic and morphological analysis of different populations of Actinostella flosculifera (Le Sueur, 1817) species complex throughout the Caribbean Sea, the Gulf of Mexico, and Brazil, and on the descriptions of Barragán et al . [1] from the Caribbean Sea and Ocaña (1994) from the Canary Islands (CI), as well as other studies in Sout...
Two species of the genus Actinostella Duchassaing, 1850 are documented for the first time on the coasts of El Salvador: A. bradleyi (Verrill, 1869) and A. californica (McMurrich, 1893). Both species are briefly described, and images of live specimens showing their main external features are provided, as well as images of histological sections showi...
Anthopleura is one of the most speciose genera within the family Actiniidae. This genus is particularly characterized by its members having both verrucae on the column and acrorhagi on the margin. In the region of the Baja California Peninsula , in the Mexican Pacific, six species of Anthopleura have been documented, which are relatively well defin...
The genus Antholoba Hertwig, 1882 (Actiniaria, Enthemonae) is characterized by the presence of short and numerous tentacles, a folded oral disc in lobes or cup-shaped with an expanded distal part, transversely wrinkled body wall surface, a very long mesogloeal sphincter, parietobasilar muscles poorly developed, and the absence of acontia. Currently...
We report the first records of the sea anemones Anthopleura mariscali , Anthopleura nigrescens , and Exaiptasia diaphana in the Protected Natural Area of Los Cóbanos and Punta Amapala on the coast of El Salvador.

Sea anemones (order Actiniaria) are organisms of the phylum Cnidaria, one of the most biodiverse groups of anthozoans, and they are characterized by being sedentary, solitary marine animals with a polypoid shape. At present, little is known about the actiniarians in the state of São Paulo. Only 14 species of sea anemones have been recorded at the s...
Background
Diadumene lineata is one of the most widespread sea anemone species worldwide. Although this species has been reported a few times on the Argentine coast since 2004, its identification has traditionally been based on external morphological characteristics, and in most cases no voucher specimens are available to support previous records....
Background
Ceriantharia is a subclass of the phylum Cnidaria, which comprises tube-dwelling marine invertebrates. This subclass is composed of three families, including Arachnactidae, with two known genera. Currently, the genus Arachnanthus has five valid species recorded from Australia, the Mediterranean Sea and both the Southern and Northern Paci...
Bunodeopsis pelagica is one of the few species of sea anemones known to be found in the floating algae of Sargassum spp. It has been reported in the North Atlantic, particularly in the Canary Islands and the coast of Jamaica. The present study is the first to report the occurrence of B. pelagica in the Mexican Atlantic, found as epiphyte on Sargass...
The attention towards non-native sea anemone introductions has been steadily increasing as multiple species are reported from new locations each year. However, a lack of monitoring efforts and difficulties associated with the detection and identification of these species may result in overlooking introductions in certain areas. In the southern hemi...
