Microanatomy of the cubopolyp,Tripedalia cystophora (Class Cubozoa) [PDF]
The microanatomy of a cubopolyp (polypoid stage of Cubomedusae) is described for the first time. The 0.5–1.0 mm long polyp ofTripedialia cystophora has an oral cone with special lip cells at the mouth. Next is a baggy calyx occasionally followed by a slender stalk. The basal region is surrounded by a thin periderm.

Prominent system of RFamide immunoreactive neurons in the rhopalia of box jellyfish (cnidaria: Cubozoa) [PDF]
AbstractThe four visual sensory structures of a cubomedusa, the rhopalia, display a surprisingly elaborate organization by containing two lens eyes and four bilaterally paired pigment cup eyes. Peptides containing the peptide sequence Arg‐Phe‐NH2 (RFamide) occur in close association with visual structures of cnidarians, including the rhopalia and ...

Elucidation of Medusozoan (Jellyfish) Venom Constituent Activities Using Constellation Pharmacology
Within the phylum Cnidaria, sea anemones (class Anthozoa) express a rich diversity of ion-channel peptide modulators with biomedical applications, but corollary discoveries from jellyfish (subphylum Medusozoa) are lacking.

Phylogenomic Analyses Support Traditional Relationships within Cnidaria. [PDF]
Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic relationships among major ...

Range expansion of two box jellyfish (Cnidaria, Cubozoa) in southern Gulf of Mexico [PDF]
We report range extensions of Chiropsalmus quadrumanus (Müller, 1859) and Tripedalia cystophora Conant, 1897 to 2 coastal lagoons in the southern Gulf of Mexico. These new records are the first for these species in Yucatán and Mexico.
