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 is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
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 ...
These receptors in the bill dominate the somatotopic map of the platypus brain, in the same way human hands dominate the Penfield homunculus map. [ 55 ] [ 56 ] The platypus can feel the direction of an electric source, perhaps by comparing differences in signal strength across the sheet of electroreceptors, enhanced by the characteristic side ...
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.

Make sure you know what these plants look like and where you can find them. This guide includes common plants that are toxic to the touch and to eat. A guide to some of NC’s most dangerous ...
California is in one of the world’s 36 biodiversity hot spots and is home to more than 6,000 types of native plants, including hundreds of wildflower species. Only a few other places on Earth ...
Invasive species in California, the introduced species of fauna−animals and flora−plants that are established and have naturalized within California. Native plants and animals can become threatened endangered species from the spread of invasive species in natural habitats and/or developed areas (e.g. agriculture, transport, settlement).
