A spider envenomation occurs whenever a spider injects venom into the skin. Not all spider bites inject venom – a dry bite, and the amount of venom injected can vary based on the type of spider and the circumstances of the encounter. The mechanical injury from a spider bite is not a serious concern for humans.
The outcome depends on the type of snake, the area of the body bitten, the amount of snake venom injected, the general health of the person bitten, and whether or not anti-venom serum has been administered by a doctor in a timely manner.

Envenomation of a human by a scorpion may affect the sympathetic or parasympathetic systems depending on the species of scorpion. Some of the more severe side effects include respiratory distress syndrome, pulmonary edema, cardiac dysfunction, impaired hemostasis, pancreatitis, and multiple organ failure.
Venom is produced in a specialised gland (or glands) and is delivered through hollow fangs or a stinger in a process called envenomation. The main function of venom is to disrupt the physiological processes of the wounded animal through neurotoxic cytotoxic, myotoxic, or haemotoxic mechanisms. This can then help in certain processes such as ...
One other genus in the family Macrothelidae has been reported to cause severe symptoms in humans. Severe bites have been attributed to members of the genus Macrothele in Taiwan, but no fatalities.
