Actiniaria

Composition, biometry and statistical relationships between the cnidom and body size in the sea anemone Oulactis mus cosa (Cnidaria: Actiniaria).

Basilar musculature, for instance, has been traditionally employed on taxonomic keys (Stephenson, 1935; Carlgren, 1949) to distinguish large groups within Actiniaria. Certain muscles such as the sphincter not only vary in shape and degree of development, but also in the tissue derivation (endodermal or mesogleal), which, until today, has been particularly useful to define families.

Ontogenetic influences on carbon flux in Aulactinia stelloides polyps (Anthozoa: Actiniaria) and their endosymbiotic algae.

Sea anemones are polyp animals of Actiniaria, an order of skeletonless Anthozoa.

We assessed global latitudinal distribution in species of sea anemones, which constitute the exclusively marine order Actiniaria (phylum Cnidaria).

The validity of Anthothoe chilensis (Actiniaria, Sagartiidae) and its distribution in Southern Hemisphere.

The complement of cnidae distinguishes the anthozoan subclasses Hexacorallia and Octocorallia (reviewed in Daly et al., 2003), and morphology of the nematocyst capsule provides the only morphological evidence for monophyly of the hexacorallian order Actiniaria (Reft and Daly, 2012).

Sea anemones (Actiniaria) are solitary, ocean dwelling member of the phylum Cnidaria and the class Anthozoa.

the valid name of a common North Pacific sea anemone (Cnidaria: Actiniaria: Acontiaria).

Embryonic and larval development in the Actiniaria are diverse, often being influenced by the yolk content of the eggs, which varies among species (Uchida and Yamada, 1968; Mergner, 1971; Campbell, 1974; Spaulding, 1974; Conn, 1991).

Sea anemones (order Actiniaria) make good subjects for a scaling study for four reasons.
