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.

Platypus venom is entirely different from other venomous creatures. While more research is needed, scientists believe it contains specific proteins that target the nervous system. Heptapeptide 1 ...
The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, 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 appear ...
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]
A platypus bill may look like a duck’s bill, but it has a secret ability. The bill contains receptor cells that detect the electric signals made by all living things. As it swims in the water ...
Humans did not evolve from either of the living species of chimpanzees (common chimpanzees and bonobos) or any other living species of apes. [174] Humans and chimpanzees did, however, evolve from a common ancestor. [175] [176] This most recent common ancestor of living humans and chimpanzees would have lived between 5 and 8 million years ago. [177]
Bücherl states that venomous animals must possess at least one venom gland, a mechanism for excretion or extrusion of the venom, and apparatus with which to inflict wounds. 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 ...
The definition of "venomous" becomes less distinct here, however, and whether some species are truly venomous is still debated.
