Venomous or Poisonous – Animals, Plants, Mushrooms, and More

Print Friendly

Venomous animals, poisonous plants, mushrooms, and substances produced by microbes, inflict considerable damage to humans and other animals throughout the world.  In scientific lingo, the entire subject is referred to as toxinology and the injurious natural substances as toxins. Thus, toxinology is a subset of the broader discipline of toxicology, and toxins could be considered a sub-category of toxicants, which is the proper word to use more generally for hazardous substances. Venomous organisms use a specialized delivery system such as fangs to deliver their venom.  Venomous animals come in all sizes and shapes and can be found certainly among the snakes, lizards, mammals (e.g. platypus), fish (e.g. stingray), arthropods such as spiders and scorpions, insects such as bees and ants, and more.  The World Health Organization estimates that at least 421,000 envenomings and 20,000 deaths occur worldwide from snakebite each year.  Some animals, such as the fugu fish (or puffer fish), though not venomous, can be poisonous when eaten.  Many plants and plant parts are poisonous to man.  The International Society on Toxinology is a professional group dedicated to advancing knowledge on the properties of toxins and antitoxins.  Interestingly, some toxins are being used as research tools, diagnostic agents, and even therapeutic agents to treat disease, due to their biological potency and specificity.  The profession of clinical toxinologist focuses on the effects of exposure to toxins in animal venoms or plant poisons.

All of the following resources are suitable for general audiences, though some may also hold special appeal for audiences as marked  (Also for Kids or Also Scholarly; Video, $).
