Riftia pachyptila, commonly known as the giant tube worm and less commonly known as the giant beardworm, is a marine invertebrate in the phylum Annelida [1] (formerly grouped in phylum Pogonophora and Vestimentifera) related to tube worms commonly found in the intertidal and pelagic zones.
Ergotism (pron. / ˈ ɜːr ɡ ə t ˌ ɪ z ə m / UR-gət-iz-əm) is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus—from the Latin clava "club" or clavus "nail" and -ceps for "head", i.e. the purple club-headed fungus—that infects rye and other cereals, and more recently by the action of a number of ...
Toxication, toxification or toxicity exaltation is the conversion of a chemical compound into a more toxic form in living organisms or in substrates such as soil or water. The conversion can be caused by enzymatic metabolism in the organisms, as well as by abiotic chemical reactions .
Lamellibrachia is a genus of tube worms related to the giant tube worm, Riftia pachyptila.They live at deep-sea cold seeps where hydrocarbons (oil and methane) leak out of the seafloor, and are entirely reliant on internal, sulfide-oxidizing bacterial symbionts for their nutrition.
Toxungens have evolved in a variety of animals, including flatworms, [4] insects, [5] [6] arachnids, [7] cephalopods, [8] amphibians, [9] and reptiles. [10]Toxungen use possibly also exists in birds, as a number of species deploy defensive secretions from their stomachs, uropygial glands, or cloacas, and some anoint themselves with heterogenously acquired chemicals from millipedes ...
A trophosome is a highly vascularised organ found in some animals that houses symbiotic bacteria that provide food for their host. Trophosomes are contained by the coelom of tube worms (family Siboglinidae, e.g. the giant tube worm Riftia pachyptila) [1] and in the body of symbiotic flatworms of the genus Paracatenula.
[4] [5] It has had uses in traditional medicine, but the discovery of toxic pyrrolizidine alkaloids in the plant has resulted in liver health concerns. Tussilago farfara is the only accepted species in the genus Tussilago , although more than two dozen other species have at one time or another been considered part of this group.
Frenulata, "beard worms", is a clade of Siboglinidae, "tube worms".They are one of four lineages with numerous species. [1] [2] They may be the most basal clade in the family. [3]
