New phylogenomic and comparative analyses provide corroborating evidence that Myxozoa is Cnidaria
Molecular Phylogenetics and Evolution, 2014 Myxozoa, a diverse group of morphologically simplified endoparasites, are well known fish parasites causing substantial economic losses in aquaculture. Despite active research, the phylogenetic position of Myxozoa remains ambiguous.

Abstract The Cnidaria (formerly known as Coelenterata) are most obviously characterized by their radial, or sometimes more strictly biradial, symmetry (p. 101). The basic structure is saclike with a single terminal opening, the mouth, which also functions as an anus.

The phylum Cnidaria or Coelenterates includes sea anemones, jellyfish, hydras, sea fans, and, of course, the corals. With few exceptions they are all marine organisms and most are inhabitants of shallow water. In spite of the great variation in shape, size, and mode of life, they all possess the same basic metazoan structural features: an internal ...

The role of Cnidaria in evolution and ecology
Italian Journal of Zoology, 2005 The recent setting of specific features of the Cnidaria into evolutionary and ecological frameworks suggests the centrality of this phylum in many fields of the life sciences.

Phospholipase A2 (PLA2) is an enzyme present in snake and other venoms and body fluids. We measured PLA2 catalytic activity in tissue homogenates of 22 species representing the classes Anthozoa, Hydrozoa, Scyphozoa and Cubozoa of the phylum Cnidaria. High PLA2 levels were found in the hydrozoan fire coral Millepora sp.

This chapter examines the phylum Cnidaria which features a highly diverse assemblage of anemones, corals, jellyfish, and their kin. The phylum consists of 13,300 described living species, all of which are predators (or highly modified parasites) that feature forms of cnidae, polypoid, or medusoid.

¿Por qué estudiar cnidarios? ¿Por qué algunos nos interesamos en ellos? Debe haber tal vez tantas respuestas posibles como especialistas en la materia; los cnidarios son criaturas tan extrañas como hermosas, son importantes ecológica y evolutivamente y relevantes para muchas actividades humanas.
