The starlet sea anemone (Nematostella vectensis) is a species of small sea anemone in the family Edwardsiidae native to the east coast of the United States, with introduced populations along the coast of southeast England and the west coast of the United States (class Anthozoa, phylum Cnidaria, a sister group of Bilateria).

Nematostella is a genus of sea anemones in the family Edwardsiidae. Of the three species in the genus, the best known is the starlet sea anemone (N. vectensis), which has been extensively studied as a model organism in fields such as genetics, evolution, and ecology. [1] The defining morphological apomorphy of Nematostella is the presence of ...
Nematosomes are multicellular motile bodies found in the gastrovascular cavity of the model sea anemone Nematostella vectensis starlet sea anemone.First described by Stephenson in 1935, [1] nematosomes are the defining apomorphy (synapomorphy) of the genus Nematostella but have received relatively little study.
Upon fertilization, a primary planula develops. Instead of direct development into an adult polyp like many other anemone species such as its close relative Nematostella vectensis, [12] it infects a species of pelagic ctenophore known as Mnemiopsis leidyi.
An unknown illness first discovered in three children who ate a bat has rapidly killed more than 50 people in northwestern Congo over the past five weeks, health experts say.
Cnidaria such as Hydra and the sea anemone Nematostella vectensis are attractive model organisms to study the evolution of immunity and certain developmental processes. [185] Other organisms that have been genetically modified include snails, [186] geckos, turtles, [187] crayfish, oysters, shrimp, clams, abalone, [188] and sponges. [189]

Ivell's sea anemone is a tiny, worm-like anemone up to 20 mm (0.79 in) long and 1.5 mm (0.059 in) diameter; the column is similar to other Edwardsia spp. There are twelve transparent tentacles, arranged in two cycles, nine tentacles in the outer cycle and three in the inner cycle.
