It is unknown whether the pain caused is a result of the associated edema around the wound or the venom has a component that acts directly on the pain receptors. The platypus venom has a broadly similar range of effects and is known to consist of a similar selection of substances to reptilian venom, and appears to have a different function from ...
When a platypus feels threatened, it will stab its spurs into its attacker and inject this toxic venom. Fortunately for humans, platypus venom isn’t fatal, but it does cause extreme pain. In ...
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 sting. The venom apparatus in this definition encompasses both the gland and the injection device, which must be directly connected.
The Australian red-back and North American widow species live near humans and bites are frequent, numbering thousands yearly. The venom produces very painful effects including muscle spasms, 'tetanus-like' contractions, nausea and vomiting, and severe generalized pain. A serious bite will often require a short hospital stay to control pain.
Platypuses may have some duck-like characteristics, but they are a rare type of mammal called a monotreme. Monotremes differ from other mammals because they lay eggs instead of giving birth. There ...

A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom, although not all stings are venomous.
In most cases, people who get a tick bite never even notice the bite itself thanks to the tick's biology. Ticks have compounds in their saliva that "prevent pain, clotting and an immune reaction ...
Many arthropods bite or sting in order to immobilize their prey or deter potential predators as a defense mechanism. Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While ...
