Here we describe a new species of sea anemone from the family Aiptasiidae based on specimens collected from the Gulf of Mexico (USA: Florida & Alabama). Accounts of this species have been known since the early 1990’s, primarily from an underwater field guide and hobbyist aquarium literature under the name “Lightbulb Anemone.” We describe it as a ne...
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 phylog...
The symbiosis between sea anemones and hermit crabs is ubiquitous in the marine environment (except in the poles), occurring from shallow to deep waters; it involves one or more anemones living on a shell inhabited by a hermit crab. The anemone-crab partnership is a mutualism in which hermit crabs provide a hard substrate, increased access to oxyge...
The clownfish-sea anemone symbiosis has been a model system for understanding fundamental evolutionary and ecological processes. However, our evolutionary understanding of this symbiosis comes entirely from studies of clownfishes. A holistic understanding of a model mutualism requires systematic, biogeographic, and phylogenetic insight into both pa...
Edwardsia migottoi sp. nov., a new species of burrowing anemone from the Southeast coast of Brazil, is described. It is also the first species of the genus reported from the Southwestern Atlantic. It is characterized by a rusty brown deciduous periderm, eight longitudinal rows of tubercles with nemathybomes, and nemathybomes with two types of nemat...

... Examples of regular octamerous symmetry in actiniarians are found in Edwardsiidae Andres, 1881 and among Actinostoloidea Carlgren, 1932(Stomphia (Gosse, 1859, Sicyonis Hertwig, 1882), Phymanthidae Andres, 1883 (some species of Phymanthus Milne Edwards & Haime, 1851), Andvakiidae (L. octoradiata Carlgren, 1938), Aiptasiidae Carlgren, 1924a (some species of Bartholomaea Duchassaing de Fombressin & Michelotti, 1864; Aiptasiogeton Schmidt, 1972a), Actiniidae Rafinesque, 1815 (Bunodactis octoradiata (Carlgren, 1898) [authorship date traditionally attributed to 1899 although original description was published in 1898, see Rodríguez et al., 2023] and Peachiidae Hamilton, Daly & Rodríguez, 2022in Hamilton et al., 2022(Metapeachia tropica (Panikkar, 1938]; in addition, there are some species within some genera with octomerous symmetry (e.g., species within Sagartiogeton Carlgren, 1924b) (reviewed in Grebelny, 1982). ...

... In addition, five polyps of zoanthid Zoanthus sociatus (Ellis, 1768) associated with O. bicornuta ( Figure 4A) were also observed. The interspecific relationships of sea anemones with crustaceans have been well documented (Wirtz & Diesel, 1983;Fautin et al., 1995;Wirtz, 1997;Acuña et al., 2003;Gusmão et al., 2019Gusmão et al., , 2020among others). Furthermore, many of these crustacean species associate with sea anemones to protect themselves against predators such as fish and octopus (Wirtz, 1997), they also feed on anemone regurgitates and mucus from the anemone's surface, and even crops the tips of its host's tentacles (Wirtz & Diesel, 1983;Fautin et al., 1995). ...
... Also, discovery approaches based on more sensitive criteria other than reciprocal monophyly to delineate species (e.g., the criterion of mutual allelic exclusivity; Doyle, 1995;Flot et al., 2010), such as haplowebs (single-locus) and conspecificity matrices (multi-locus), have been broadly used in corals despite their need for qualitative interpretations (Adjeroud et al., 2013;Flot et al., 2013;Johnston et al., 2017;Terrana et al., 2021). As a result, ILS appears common; notably, conventionally used DNA barcodes appear to hold signatures of ILS, particularly in the slowly evolving mitochondrial genomes/genes of corals and sea anemones (Fukami et al., 2000;Quattrini et al., 2019Quattrini et al., , 2023Titus, Benedict, et al., 2019). ...

... The presence of eight macrocnemes led Carlgren (1949) to transfer the sole species in the genus, H. papillosus Carlgren, 1937, from the family Halcampoididae Appellöf, 1896 to Edwardsiidae. Although Gusmão et al. (2016) kept Halcampogeton within Edwardsiidae, they consider the taxon problematic and possibly belonging to a different family due to its strong dodecamerous organization (see Gusmão et al. 2016). Regardless of its familial placement, H. papillosus has twelve rows of conspicuous solid papillae with very large nematocysts which are clearly absent from Halcampulactis solimar sp. ...
