The blastoporal organiser of a sea anemone [PDF]
SummaryIn 1924 Hilde Mangold and Hans Spemann transplanted the dorsal blastopore lip of an amphibian embryo to a host embryo's ventral side. This experiment revealed that the dorsal blastopore lip can act as an ‘organiser’ to induce a secondary body axis [1].

Sea anemones (Anthozoa: Actiniaria) from the coast of Yucatán, Mexico
Sea anemones (order Actiniaria) are among the benthic marine invertebrate groups that commonly inhabit a wide range of coastal environments, including seagrass meadows, rocky bottoms, coral reefs, sandy patches, mangroves, and artificial substrates ...

The article presents a potentially obligate association of a pleustid amphipod of the genus Pleusymtes (Crustacea: Amphipoda: Pleustidae) with the large sea anemone Urticina eques (Gosse, 1858) (Anthozoa: Actiniaria: Actiniidae) from shallow waters of ...

Sea anemone model has a single Toll-like receptor that can function in pathogen detection, NF-κB signal transduction, and development [PDF]
In organisms from insects to vertebrates, Toll-like receptors (TLRs) are primary pathogen detectors that activate downstream pathways, specifically those that direct expression of innate immune effector genes.

Defending against pathogens - immunological priming and its molecular basis in a sea anemone, cnidarian [PDF]
Cnidarians, in general, are long-lived organisms and hence may repeatedly encounter common pathogens during their lifespans. It remains unknown whether these early diverging animals possess some type of immunological reaction that strengthens the defense

Sea anemones may thrive in a high CO2 world [PDF]
Increased seawater pCO 2, and in turn 'ocean acidification' (OA), is predicted to profoundly impact marine ecosystem diversity and function this century.

The feeding ecology of the intertidal sea anemones Phymactis clematis Dana, 1849, Aulactinia marplatensis (Zamponi, 1977) and A. reynaudi (Milne-Edwards, 1857) (Actiniaria: Actiniidae) from Punta Cantera and Santa Clara del Mar (Argentina) was studied ...

Members of phylum Cnidaria are an ancient group of venomous animals and rely on a number of specialized tissues to produce toxins in order to fulfil a range of ecological roles including prey capture, defence against predators, digestion and aggressive ...

Varied effects of algal symbionts on transcription factor NF-κB in a sea anemone and a coral: possible roles in symbiosis and thermotolerance [PDF]
Many cnidarians, including the reef-building corals, undergo symbiotic mutualisms with photosynthetic dinoflagellate algae of the family Symbiodiniaceae.

Phylogenetic relationships among the clownfish-hosting sea anemones
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.
