Hidden among Sea Anemones: The First Comprehensive Phylogenetic Reconstruction of the Order Actiniaria (Cnidaria, Anthozoa, Hexacorallia) Reveals a Novel Group of Hexacorals
Based on the comprehensive phylogeny, a new formal higher-level classification is proposed for Actiniaria composed of only two suborders, Anenthemonae and EnthemonAE and erect subgroups within these two newly-erected suborders.
First report on large scleractinian (Cnidaria: Anthozoa) accumulations in cold-temperate shallow water of south Chilean fjords
South Chilean fjords contain an astonishing diverse benthic macrofauna of which anthozoans form a major portion, and it cannot be excluded that these coral communities are in danger before they are even studied.
Zoanthids (Cnidaria: Hexacorallia: Zoantharia) from shallow waters of the southern Chilean fjord region, with descriptions of a new genus and two new species
The three most abundant zoanthid species in shallow waters of the southern Chilean fjord region are described and it is revealed that two of them are new to science; these are described as Mesozoanthus fossii gen. n.

The results of the phylogenetic analyses indicate that the diagnostic morphological characters used in the family‐level taxonomy of acontiate actiniarians such as the nematocysts of the acontia, the marginal sphincter muscle, and mesenteries divisible into macro‐ and micro‐cnemes, have to be revisited, as these features are highly homoplasious.
Chitons (Mollusca: Polyplacophora) from the southern Chilean Comau Fjord, with reinstatement of Tonicia calbucensis Plate, 1897
Nine species, belonging to four families, observed and collected in shallow water between 2003 and 2005 and for the first time an infection by an endoparasitic nematode is reported in chitons.
A review of the Scleractinia (Cnidaria: Anthozoa) of Chile, with the description of two new species
All records of the 23 scleractinian species known to occur off Chile are reviewed, including the first records of seven for this coastline. Two species are described as new: Caryophyllia huinayensis…
Biodiversity of Chilean sea anemones (Cnidaria: Anthozoa): distribution patterns and zoogeographic implications, including new records for the fjord region

The results show the continuation of species characteristic for the exposed coast south of 42°S and the joining of typical fjord species at this latitude, which differs from the classical concept of an abrupt change in the faunal composition south of42°S.
Hydrozoa, fjord Comau, Chile.
The shallow-water hydrozoan fauna of fjord Comau is surveyed. A total of thirty three species were recorded. They have been assigned to eight families of Athecata, eight families of Thecata, two…
Stable isotope variability in a Chilean fjord food web: implications for N- and C-cycles
We analysed carbon (δ 13 C) and nitrogen (δ 15 N) isotope ratios of organisms and biogenic tissues from Comau Fjord (southern Chile) to characterise benthic food webs and spatial isotope vari-…
A new species of sea anemone from Chile, Anemonia alicemartinae n. sp. (Cnidaria: Anthozoa). An invader or an indicator for environmental change in shallow water?
Evidence of frequent fission and the absence of fertile males in the sample indicate a predominance of asexual reproduction in the population of Chilean sea anemones, suggesting that it has been increasing in abundance and/or expanding its range during the last 50 years.
