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 for hunting and for self-defense.
The process kills both fish eggs and fish too young to sell. It also destroys the surrounding habitat, including coral reefs in the area. This damage is estimated to have cause $99.2 billion in losses a year, according to a study by Rhodora Azanza of the University of the Philippines. [ 44 ]
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 ...
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.

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