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.

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 ...
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 ...
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 ...
One photo shows the first-of-its-kind platypus along the riverbank near several turtles. Its coloring makes it easy to spot among the surrounding brown tones of the logs, turtles and murky water.
Male echidnas have non-venomous spurs on the hind feet, similar to the venomous male platypus. [ 15 ] Due to their low metabolism and accompanying stress resistance, echidnas are long-lived for their size; the longest recorded lifespan for a captive echidna is 50 years, with anecdotal accounts of wild individuals reaching 45 years.
