Metridiidae Carlgren, 1893 [1] |
Metridiidae is a family of sea anemones in the order Actiniaria. [2]
Members of the family Metridiidae are characterised by having a mesogloeal sphincter muscle and by the mesenterial arrangement, with the mesenteries not being divided into macronemes and microcnemes. The acontia typically have microbasic b-mastigophors and microbasic amastigophors, though the latter are not always present in adults. [1]
The following genera are recognised by the World Register of Marine Species (WoRMS): [3]
Of these, Metridium is the most speciose while Paraisometridium is monotypic.
