Impacts of barite and bentonite sedimentation on the behaviour, mucus production and cnidocytes of the deep-sea coral Flabellum (Ulocyathus) alabastrum [PDF]
Deep Sea Research Part II: Topical Studies in OceanographyAs oil and gas exploration expands in deep-sea environments, understanding the impacts of wastes produced by this industry is urgent. One of the main wastes of offshore drilling is the discharge of drill muds, commonly including barite and bentonite clay.

That Stinging Sensation: Modularity and the Origin of the Stinging Cell. [PDF]
Integr Comp BiolSynopsis All cells arise through division of other cells; thus, cells with new functions (novel cell types) must evolve from ancestral cells with a different function. How, then, do novel cell types arise? Each cell is a composite of many functions that,

Sea Anemone Membrane Attack Complex/Perforin Superfamily Demonstrates an Evolutionary Transitional State between Venomous and Developmental Functions. [PDF]
Mol Biol EvolGene duplication is a major force driving evolutionary innovation. A classic example is generating new animal toxins via duplication of physiological protein-encoding genes and recruitment into venom.

The Electrophysiology of Cnidocytes [PDF]
Journal of Experimental Biology, 1987 ABSTRACT Electrical properties of cnidocytes isolated from the hydroid Cladonema and the scyphomedusa Chrysaora were examined using current- and voltage-clamp recording techniques. The stenoteles of Cladonema produced action potentials when depolarized above 0mV.

A developmental role for the chromatin-regulating CoREST complex in the cnidarian Nematostella vectensis. [PDF]
BMC Biol, 2022 Background: Chromatin-modifying proteins are key players in the regulation of development and cell differentiation in animals. Most chromatin modifiers, however, predate the evolution of animal multicellularity, and how they gained new functions and ...

Preparation and Properties of Cnidocytes from the Sea Anemone Anthopleura elegantissima
The Biological Bulletin, 1988 Cnidocytes were isolated from the tentacles and acrorhagi of Anthopleura elegantissima by enzymatic treatment with papain followed by centrifugation in a Percoll-containing medium to produce a concentrated fraction of these cells. The morphology of the isolated cells, as revealed by light and electron microscopy, showed that these cells had intact ...

Mating in the box jellyfish
Journal of Morphology, 2015 ABSTRACTWithin cubozoans, a few species have developed a sexual reproduction system including mating and internal fertilization. One species, Copula sivickisi, is found in a large area of the indo pacific. They have separate sexes and when mature males and females meet they entangle their tentacles and the males transfer a sperm package, a ...

Effects of Proline and Glycine on the Cnidocyte Discharge of Hydra magnipapillata [PDF]
, 2015 The sense of taste enables animals to utilize environmental cues to detect favorable foods. Through specialized sensory receptors, Cnidarians employ stinging cells called cnidocytes to perform a variety of activities such as locomotion, capturing prey ...
