A unique feature of the venom is the presence of a D-amino acid. This is the only known such example in mammalian systems. [8] This venom appears to be related to that of several species that are not part of the platypus's evolutionary lineage, such as certain fish, reptiles, insectivores, and spiders, sea anemones, and starfish.

The platypus (Ornithorhynchus anatinus), [4] sometimes referred to as the duck-billed platypus, [5] is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species ...
This complex chemical cocktail is a dangerous defense, but it might also have beneficial qualities for humans as well. One hormone found in platypus venom, glucagon-like peptide-1 (GLP-1), plays a ...
Mebs writes that venomous animals produce venom in a group of cells or gland, and have a tool, the venom apparatus, which delivers the venom by injection during a bite or sting. The venom apparatus in this definition encompasses both the gland and the injection device, which must be directly connected.
Despite their awkward appearance, the platypus has a superpower-like sixth sense that it uses to hunt. With a beaver’s tail, webbed feet, and a duck’s bill, platypuses are one of the world’s ...
The echidna spurs are vestigial and have no known function, while the platypus spurs contain venom. [42] Molecular data show that the main component of platypus venom emerged before the divergence of platypus and echidnas, suggesting that the most recent common ancestor of these taxa was also possibly a venomous monotreme. [43]
The definition of "venomous" becomes less distinct here, however, and whether some species are truly venomous is still debated. European mole (Talpa europaea) Platypus (Ornithorhynchus anatinus) [a] Eurasian water shrew (Neomys fodiens) Mediterranean water shrew (Neomys anomalus) Northern short-tailed shrew (Blarina brevicauda)
Below is an extensive, if incomplete, list of plants containing one or more poisonous parts that pose a serious risk of illness, injury, or death to humans or domestic animals. There is significant overlap between plants considered poisonous and those with psychotropic properties , some of which are toxic enough to present serious health risks ...
