Envenomation is the process by which venom is injected by the bite or sting of a venomous animal. [ 1 ] Many kinds of animals, including mammals (e.g., the northern short-tailed shrew , Blarina brevicauda ), reptiles (e.g., the king cobra ), [ 2 ] spiders (e.g., black widows ), [ 3 ] insects (e.g., wasps ), and fish (e.g., stone fish ) employ ...
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 ...
There is a lot of evidence to support the venom metering hypothesis. For example, snakes frequently use more venom during defensive strikes, administer more venom to larger prey, and are capable of dry biting. A dry bite is a bite from a venomous snake that results in very little or no venom expulsion, leaving the target asymptomatic. [89]

This species likely may occur in other neighboring islands, but this remains unconfirmed. Records from the Calamianes group and Palawan require confirmation. [8]
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.

In Australia, C. fleckeri has caused at least 64 deaths since the first report in 1883, [17] but most encounters appear to result only in mild envenomation. [18] Among 225 analyzed C. fleckeri stings in Australia's Top End from 1991 to 2004, only 8% required hospital admission, 5% received antivenom and there was a single fatality (a 3-year-old ...
