O presente estudo objetiva descrever as ocorrências de branqueamentos dos corais e outros cnidários bentônicos no costão rochoso da Praia do Forno (Arraial Cabo, RJ), observadas em fevereiro (verão) maio (outono) 2019, relacionando-as com possíveis eventos aquecimento das águas superficiais oceano. As cartas anomalias térmicas foram obtidas pelo INMET os trabalhos campo desenvolvidos baseados P...

Palytoxin (PLTX), one the most potent marine toxins, and/or its analogs, have been identified in different marine organisms, such as Palythoa soft corals, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria. Although the main concern for human health is PLTXs entrance in the human food chain, there is growing evidence of adverse effects associated with inhalational, cutaneous, and/or oc...

Protopalythoa is a zoanthid that, together with thousands of predominantly marine species, such as hydra, jellyfish, and sea anemones, composes the oldest eumetazoan phylum, i.e., the Cnidaria. Some of these species, such as sea wasps and sea anemones, are highly venomous organisms that can produce deadly toxins for preying, for defense or for territorial disputes. Despite the fact that hundred...

Marine community datasets are key to the effective management and conservation of marine ecosystems, including coral reefs, which increasingly threatened by a myriad stressors. Although information exists for many comparatively well-studied taxa, other common groups remain be examined even such basic information. In this study, we report on zoantharian communities (Cnidaria: Anthozoa: Hexacoral...

Coral reef bleaching events are expected to become more frequent and severe in the near future as climate changes. The zoantharian Palythoa tuberculosa bleaches earlier than many scleractinian corals and may serve as an indicator species. Basic monitoring of such species could help to detect and even anticipate bleaching events, especially in areas where more sophisticated approaches that rely ...

Marine invertebrates are capable of synthesizing bioactive compounds, which may be beneficial to human health. The aim of this study was to evaluate the antioxidant, hemolytic, antimicrobial and cytotoxic activities of crude extract (70% EtOH), and dichloromethane (DCM), ethyl acetate (EtOAc), and aqueous (Aq) fractions of the marine zoanthid Palythoa caribaeorum. The phenolic compound contents...
