Comparative Aspects of Structure and Function of Cnidarian Neuropeptides

open access: yesFrontiers in Endocrinology, 2020
Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and ...

Cell proliferation in cubozoan jellyfish Tripedalia cystophora and Alatina moseri. [PDF]

open access: yesPLoS ONE, 2014
Cubozoans (box jellyfish) undergo remarkable body reorganization throughout their life cycle when, first, they metamorphose from swimming larvae to sessile polyps, and second, through the metamorphosis from sessile polyps to free swimming medusae. In the

Histological Investigation of the Female Gonads of Chiropsalmus quadrumanus (Cubozoa: Cnidaria) Suggests Iteroparous Reproduction

open access: yesDiversity, 2023
The box jellyfish Chiropsalmus quadrumanus (Chirodropida: Cubozoa: Cnidaria) is common in warm waters. Although it is assumed that external fertilization is a characteristic of Chirodropida, the life history of C.

Use of eDNA to detect and study deadly box jellyfish [PDF]

open access: green
This thesis explored the use of environmental DNA (eDNA) to detect and study box jellyfish (Chironex fleckeri) across key life-history stages. A highly specific eDNA assay enabled detection of medusae and polyps, uncovering spatially restricted ...

Box jellyfish diversity in Indian waters with an occurrence report of a deadly species of box jellyfish Chironex indrasaksajiae [PDF]

open access: yes, 2023
Box jellyfish, are among the most toxic invertebrates in the world according to many studies (Barnes 1966; Gershwin et al., 2010). Box jellyfish envenomation is caused by nematocysts, which are produced by specialised cells called nematocytes through

The bilaterally symmetric rhopalial nervous system of box jellyfish [PDF]

open access: yes, 2006
Cubomedusae, or box jellyfish, have the most elaborate visual system of all cnidarians. They have 24 eyes of four morphological types, distributed on four sensory structures called rhopalia.
