Bioluminescent Marine Cnidarians
2022This chapter deals with the total luminescent fauna of planktonic hydrozoa and scyphozoa, emission maxima in observed species of planktonic hydrozoa and scyphozoa, the description of luminescent marine species of planktonic hydrozoa and scyphozoa and their mechanism of bioluminescence.

Abstract The Phylum Cnidaria is ancient and diverse in terms of size and body shape, and includes the sea fans, sea pens, sea anemones, corals, hydroids, and jellyAsh (Fig. 1). Cnidarians possess two cell layers (diploblastic), the outer ectoderm and the inner endoderm, separated by an acellular mesoglea, or partially cellular mesenchyme

Cnidarian Origins of the Myxozoa
2015Now that we have strong evidence for the phylogenetic placement of Myxozoa within the Cnidaria it is of great interest to explore their evolutionary history. In particular, what cnidarian features may have facilitated the transition to an endoparasitic lifestyle and can we identify a potential cnidarian sister group?

Treatment of Atlantic cnidarian envenomations
Toxicon, 2009Envenomation syndromes induced by Atlantic cnidaria have been tabulated and their therapy discussed. The pharmacokinetics of the venom has been emphasized. Pain occurs instantly and reaches a zenith rapidly in the surf. The nematocysts have already penetrated the dermis and disease proceeds before help can arrive.

Abstract Important cnidarian contributions to our understanding of nervous system evolution may be found in the arrangement of conducting systems and their interactions. We see multiple, diffuse systems that interact to produce specific behaviors, the compression of conducting systems into compact directional or bidirectional conduction ...

Venomology of Marine Cnidarians
2020This chapter deals mainly with the marine cnidarian envenomations and their treatment and management. The different aspects relating to envenomations include the components of venom apparatus (nematocysts, spirocysts and ptychocysts); mechanism of cnidae discharge; characteristics and composition of marine cnidarian venoms viz.

Endosymbiosis in marine cnidarians
1992Abstract Endosymbiotic relationships with either prokaryote or algal symbionts are found in the marine benthos, in members of the Protozoa, Porifera, Cnidaria, Turbellaria, and Mollusca. This review will concentrate upon the most widespread association, that of the dinoflagellate Symbiodinium microadriaticum (zooxanthellae) and its ...
