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.

A number of spiders can cause spider bites that are medically important. Almost all spiders produce venom but only a few are able to cause significant harm to humans. [1] Two medically important spider genera have a worldwide distribution—Latrodectus and Loxosceles. Others have a limited distribution.
With so many kinds of eight-legged bugs running around (nearly 3,000 species in North America alone!), the most common house spiders are bound to pop up in your abode from time to time. And with ...
Synanceia verrucosa, a species of stonefish, is lined with dorsal spines that deliver an intensely painful and lethal venom. It is sometimes called the most venomous fish in the world. There are at least 1,200 species of venomous fish, including: Stonefishes (Synanceia spp.) Lionfishes (Pterois spp.) Scorpionfishes
