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.

It is one of the few species of venomous mammals, as the male platypus has a spur on the hind foot that delivers an extremely painful venom. The unusual appearance of this egg-laying, duck-billed, beaver-tailed, otter-footed mammal at first baffled European naturalists. In 1799, the first scientists to examine a preserved platypus body judged ...
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 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)
“Male Funnel-web spiders have short lifespans, and with approximately 150 spiders required to make just one vial of antivenom, we need the public’s help to ensure we have enough venom to meet ...
There are more than 3,500 different kinds of spiders in the U.S., but only two pose a real threat to Mississippi, Alabama and Georgia residents.
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.
“Whilst female funnel-web spiders are venomous, males have proven to be more lethal. "With having a male funnel-web this size in our collection, his venom output could be enormous, proving ...
