The gastropod-symbiotic sea anemone genus Isosicyonis Carlgren, 1927 (Actiniaria : Actiniidae): a new species from the Weddell Sea (Antarctica) that clarifies the taxonomic position of the genus [PDF]
, 2008 A second species of the sea anemone genus Isosicyonis is described and illustrated from 16 specimens collected in the Weddell Sea (Antarctica) on the Polarstern cruises ANT XVII/3, ANT XXI/2 and ANT XXIII/8. Isosicyonis striata n. sp.

A genome wide survey reveals multiple nematocyst-specific genes in Myxozoa
BMC Evolutionary Biology, 2018 Background Myxozoa represents a diverse group of microscopic endoparasites whose life cycle involves two hosts: a vertebrate (usually a fish) and an invertebrate (usually an annelid worm). Despite lacking nearly all distinguishing animal characteristics,

Prey Resource Utilization by Coexistent Hydromedusae from Friday Harbor, Washington, USA [PDF]
, 2002 Prey selection patterns were quantified for a sympatric group of hydromedusae from Friday Harbor, WA. Selection patterns varied between species, but were largely replicable between sample dates and resembled dietary patterns found in similar studies from

Stem cells of Hydra magnipapillata can differentiate into somatic cells and germ line cells [PDF]
, 1987 We investigated whether all stem cells of Hydra can differentiate both somatic cells and gametes or if a separate germ line exists in these phylogenetically old organisms.

Microbiome heterogeneity in tissues of the coral, Fimbriaphyllia (Euphyllia) ancora
Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.The stony coral, Fimbriaphyllia (Euphyllia) ancora, demonstrates microbiome heterogeneity across its functionally differentiated tissues. Several bacteria, including Endozoicomonas and Pseudomonas, exhibit differential abundances among these tissues. These findings not only broaden our understanding of coral‐bacteria symbiosis but also highlight the ...

The Ecological Importance of Toxicity: Sea Anemones Maintain Toxic Defence When Bleached
Toxins, 2019 Cnidarians are amongst the most venomous animals on the planet. They are also under significant threat due to the impacts of climate change. Corals and anemones undergo climate-induced bleaching during extreme environmental conditions, where a loss of ...

Sea anemone–anemonefish symbiosis: Behavior and mucous protein profiling
Journal of Fish Biology, Volume 105, Issue 2, Page 603-618, August 2024.Abstract Fish species of the genus Amphiprion (Perciformes: Pomacentridae) seek protection from predators among the tentacles of sea anemones as their natural habitat, where they live essentially unharmed from stinging by the host's nematocysts. The skin mucus of these anemonefish has been suggested as a protective mechanism that prevents the discharge

BMC Genomics, 2021 Background Lineage-specific gene expansions represent one of the driving forces in the evolutionary dynamics of unique phylum traits. Myxozoa, a cnidarian subphylum of obligate parasites, are evolutionarily altered and highly reduced organisms with a ...

The Biological Bulletin, 1924 The nematocysts of Microstoma are derived from Hydra upon which Microstoma feeds. These ingested nematocysts are delivered to the mesoderm by the endoderm of the flatworm. Within the mesoderm an amœboid cell takes charge of each nematocyst and as it is transported to the surface orients it so that the "sting-thread" has its discharging pole directed ...
