“…Scleractinia, often known as hard or stony corals, are Cnidaria phylum aquatic creatures that produce a hard bone structure (Cairns, 2007;Cairns et al, 2009). Alcyonaria, which includes roughly three thousand water-based species made up of eight-fold symmetric colonial polyps, is an Anthozoa subgroup (Ivanova, 2020). Soft corals make up the majority of the Alcyonaria subclass (Ghallab et al, 2020).…”

Ophiactis savignyi could be discovered all over the world in tropical marine environments. People could have aided in the spread of O. savignyi, particularly in the western and eastern populations of Panama's Isthmus. The brittle star Ophiactis savignyi, often known as savigny's brittle star, coexists alongside the sponge Geodia corticostylifera. The focus of this research has been to assess the functional relevance of G. corticostylifera secondary metabolites as antifoulant against mussels, protection against generalist fish, and chemical cues to affiliated brittle stars. Both in flow-through and static seawater laboratory studies, O. savignyi which has previously been connected with sponges, was given both treated and control mimics at the same time. The sponge extract was also tested for its ability to protect fish against predators and fouling. Deterrence test using chemicals indicated that the normal level of the sponge extract may also suppress generalist fish predation in the field as well as the mussel Perna perna’s normal attachment in clinical contexts. According to the findings, G. corticostylifera crude extract has many roles in the aquatic environments, apparently being accountable for this sponge's tighter relationship with O. savignyi, which protects the ophiuroid and inhibits epibionts on itself.

“…Despite the widespread use of the system for Actiniaria proposed by Rodríguez & Daly in Rodríguez et al . (2014), I adhere to Carlgren's (1949) classification, since I do not consider Rodríguez & Daly's system to be exhaustive; in my opinion, the transition to a system based on molecular markers is still premature (see Ivanova, 2020).…”

Haliactis arctica is a poorly known species of sea anemone of the family Halcampactinidae known only from the Arctic. So far, there have been no reports of it after the original description, based on a few specimens from Greenland, Spitsbergen, the Barents Sea, Novaya Zemlya and the Chukchi Sea. The rich collection of the Zoological Institute RAS, which includes more than 100 specimens, has allowed a detailed morpho-anatomical study of this sea anemone. Examination of the external and internal morphology of H. arctica indicates a noticeable variability of structural features, especially the retractor muscles, parietal muscles and acontia. Comparison of characters between H. arctica with the other representatives of Halcampactinidae shows significant differences in the organization of these anemones. Their morphological differences and also significant geographic remoteness suggest that they should be attributed to different families, however, at present it is impossible to conduct thorough molecular genetic studies that can confirm or refute this assumption.

Haloclavidae Verrill, 1899 is a family of burrowing sea anemones grouped within the superfamily Actinioidea (Rafinesque, 1815). Currently, it includes 30 species in 10 genera. Characters given for this family in descriptions of its taxa have not been consistent, with numerous exceptions to the expectations of the familial diagnosis. Previous phylogenetic analyses have shown that Haloclavidae is potentially a polyphyletic group, but resolution of relationships of the few representatives of Haloclavidae included in analyses has been problematic. Here we address questions of monophyly and affinity of Haloclavidae using three mitochondrial and two nuclear markers. We assess the monophyly of Haloclavidae in the context of all major lineages of Actiniaria Hertwig, 1882, emphasizing diversity of superfamily Actinioidea. We use parsimony-based character optimization to interpret the distribution of key traits in the superfamily. We find that Haloclavidae is not monophyletic and propose two new families, Peachiidae fam. nov. and Harenactidae fam. nov., while also retaining some species in the family Haloclavidae, so that taxonomy better reflects relationships and diversity of the group. In addition, we redescribe a species within the newly created Peachiidae, Peachia chilensis Carlgren, 1931. We use recent larval samples obtained in Antofagasta, Chile, and the histological slides from the original description to redescribe P. chilensis, to provide a complete account of cnidae, external, and internal morphology. Finally, we compare P. chilensis to other burrowing anemones found in Chile and provide an understanding of the genus Peachia that reflects recent phylogenetic perspective on diversity of anemones previously assigned to family Haloclavidae.
