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.

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...

We previously showed that an unintentionally introduced zoanthid in a home aquarium contained high concentrations of palytoxin and was likely respon...
