Taxonomy and Molecular Phylogeny of the Sea Anemone (Haddon, 1898) (Cnidaria, Actiniaria), with a Description of a New Species from Singapore.

Sea anemones (Cnidaria, Actiniaria) are a successful group of marine invertebrates found in a diverse range of environments globally. In spite of their ubiquity, identities for many sea anemones remain unverified, especially those from the Indo-West Pacific region. Here, we clarify the taxonomy of the poorly known , a shallow-water species first described from the Torres Straits in northern Australia.

Sea anemones (Cnidaria, Actiniaria) of Singapore: redescription and taxonomy of Martens in Klunzinger, 1877.

Despite the ubiquity of sea anemones (Cnidaria: Actiniaria) in tropical ecosystems, our understanding of their biodiversity and taxonomy is limited. Here we re-establish the identity of an intertidal zooxanthellate species, Martens in Klunzinger, 1877. Originally described from a single preserved specimen in the Berlin Museum by CB Klunzinger, his brief footnote lacked crucial details to positively identify the species.
