Light modulated cnidocyte discharge predates the origins of eyes in Cnidaria
Ecology and Evolution, 2021 Complex biological traits often originate by integrating previously separate parts, but the organismal functions of these precursors are challenging to infer.

Recruitment of toxin-like proteins with ancestral venom function supports endoparasitic lifestyles of Myxozoa [PDF]
PeerJ, 2021 Cnidarians are the oldest lineage of venomous animals and use nematocysts to discharge toxins. Whether venom toxins have been recruited to support parasitic lifestyles in the Endocnidozoa (Myxozoa + Polypodium) is, however, unknown. To examine this issue

Mini-Collagens in Hydra Nematocytes [PDF]
, 1991 We have isolated and characterized four collagen-related c-DNA clones (N-COL 1, N-COL 2, N-COL 3, N-COL 4) that are highly expressed in developing nematocytes in hydra.

Scientia Marina, 2000 Cnidocyst nomenclature is based on the structure of the tubule and its armature as viewed in the light microscopy (LM). Investigations utilising optically improved LM and scanning electron microscopy have revealed some errors in the interpretation of the

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 ...

Morphology and distribution of a deep-water Narcomedusa (Solmarisidae) from the northeast Pacific
Scientia Marina, 2000 Specimens of Solmaris sp. (Solmarisidae, Narcomedusae) with only four tentacles were collected in the northeast Pacific. The majority were collected in Canadian Pacific waters by Tucker trawl from stations outside the 500-m contour off the west coast of ...

Gene duplications are extensive and contribute significantly to the toxic proteome of nematocysts isolated from (Cnidaria: Anthozoa: Scleractinia) [PDF]
BMC Genomics, 2015 Gene duplication followed by adaptive selection is a well-accepted process leading to toxin diversification in venoms. However, emergent genomic, transcriptomic and proteomic evidence now challenges this role to be at best equivocal to other processess .

Effects of predation by Hydra (Cnidaria) on cladocerans (Crustacea: Cladocera)
Journal of Limnology, 2016 Planktonic cladocerans have evolved different strategies to avoid predation from vertebrates; these include changes in morphology, behavior, physiology, and/or life-history traits.
