Última Re-description of Phymactis papillosa (Lesson, 1830) and Phymanthea pluvia (Drayton in Dana, 1846) (Cnidaria: Anthozoa), two common actiniid sea anemones from the south east Pacific with a discussion of related genera Naturalis Häussermann, V.. Actiniid sea anemones possess few characteristics of taxonomic value, which makes columnar outgrowths one of the most important features for systematic work. There are two species of actiniid sea anemones known from Chile and southern Peru that exhibit a column densely covered with non-adhesive vesicles: Phymactis papillosa (Lesson, 1830) (= Phymactis clematis) and Phymanthea pluvia (Drayton in Dana, 1846). Hereby both are re-described in detail. The re-descriptions are based on observations of about 100 living animals in their habitat and in aquaria and on the examination of 21 specimens of P. papillosa and seven specimens of P. pluvia collected in Chile between 1995 and 2003. In Chile, specimens of both species occur in tide-pools, on vertical and...

Ano: 2004 URL: http://www.repository.naturalis.nl/record/214449 Redescription of Oulactis concinnata (Drayton in Dana, 1846) (Cnidaria: Anthozoa: Actiniidae), an actiniid sea anemone from Chile and Perú with special fighting tentacles; with a preliminary revision of the genera with a “frond-like” marginal ruff Naturalis Häussermann, V.. Two species of sea anemones with a conspicuous marginal ruff of frond-like structures encompassing the tentacular crown occur on the Chilean coast. Oulactis concinnata (= Isoulactis chilensis) (Drayton in Dana, 1846) is re-described in detail and further information is provided for Oulactis coliumensis (Riemann- Zürneck & Gallardo, 1990) (= Saccactis coliumensis) (both Actiniidae). The distribution of O. concinnata from Playa Las Salinas, Perú (9°19’10’’S, 78°26’30’’W), to the region of Valdivia, Chile (39°47’S, 73°21’W), lies within a zoogeographical unit known as the Peruvian Province. Re-description of O. concinnata is based on examination of 10 specimens collected between 1975 and 2003, and on observations of about 50 living anemones in their...

Ano: 2003 URL: http://www.repository.naturalis.nl/record/220304 First report on large scleractinian (Cnidaria: Anthozoa) accumulations in cold-temperate shallow water of south Chilean fjords Naturalis Försterra, G.; Häussermann, V.. South Chilean fjords contain an astonishing diverse benthic macrofauna of which anthozoans form a major portion. Azooxanthellate solitary scleractinians, which were hitherto known from major depths, were found as shallow as 8 m during several expeditions to the south Chilean fjord region. At some sites, stony corals dominate the macrofauna and form dense aggregations, which may cover several 10’s of square meters in depths below 25 m. The discovery of these communities in shallow water for the first time allows for in situ observations and structural analysis of these populations by means of SCUBA diving. For further studies, living and dead corals were sampled, photographed, and dried for preservation. Several specimens and tissue samples were preserved...
