Journal of Experimental Biology, 2006 ![Figure][1] The group Cnidaria, which includes jellyfish, anemones, corals and the familiar freshwater Hydra , is not generally known for its speed. In fact, it was only in the mid 18th century that they were first accepted as animals by biologists, having been categorized alongside ...

Distinct cellular expression pattern of annexins in Hydra vulgaris. [PDF]
, 1992 The annexins are a structurally related family of Ca2+ and phospholipid binding proteins whose function has not been clearly defined. Further investigations of annexin function may be enhanced by studying simpler organisms that express fewer annexin gene

Excitation of Nematocysts [PDF]
Nature, 1942 THERE has in the past been considerable discussion concerning the nature of the stimulus which causes the nematocysts of Cœlenterates to discharge, In some cases, it is quite clear that the mechanical stimulus to the cnidoblast causes an, explosion of the enclosed nematocyst.

A molecular filter for the cnidarian stinging response
eLife, 2020 All animals detect and integrate diverse environmental signals to mediate behavior. Cnidarians, including jellyfish and sea anemones, both detect and capture prey using stinging cells called nematocytes which fire a venom-covered barb via an unknown ...

The cnidarian parasite Ceratonova shasta utilizes inherited and recruited venom-like compounds during infection [PDF]
PeerJ, 2021 Background Cnidarians are the most ancient venomous organisms. They store a cocktail of venom proteins inside unique stinging organelles called nematocysts.

Fluid Dynamics of Ballistic Strategies in Nematocyst Firing
Fluids, 2020 Nematocysts are stinging organelles used by members of the phylum Cnidaria (e.g., jellyfish, anemones, hydrozoans) for a variety of important functions including capturing prey and defense. Nematocysts are the fastest-known accelerating structures in the

Immunocompetence in Hydra. Epithelial cells recognize self-nonself and react against it [PDF]
, 1986 The evolution of effective immunologic defense mechanisms in multicellular organisms involves the ability of host cells to distinguish betweeen self and nonself and to react appropriately to eliminate foreign tissue.
