The term "poisonous species" typically refers to living organisms that possess natural toxins capable of causing harm or death if consumed, inhaled, or touched. Here's a list of examples:
Snakes: Venomous snakes such as rattlesnakes, cobras, vipers, and mambas can cause serious injury or death through their venomous bites.
Scorpions: Certain scorpion species possess venom potent enough to be lethal to humans.
Spiders: Some spiders have venomous bites that can be dangerous, such as the black widow spider and the brown recluse spider.
Marine Life: Many marine creatures are poisonous, including jellyfish like the box jellyfish or Portuguese man o' war, and cone snails.
Fungi: Toadstools, mushrooms, and other fungi can contain harmful substances, like the highly toxic Amanita phalloides (death cap).
Fish: Certain types of fish are poisonous, such as pufferfish, which contain tetrodotoxin in their internal organs.
Amphibians: Some frogs, salamanders, and other amphibians secrete toxic substances through their skin as a defense mechanism.
Insects: Bees, wasps, ants, and caterpillars like the puss moth can deliver painful and sometimes life-threatening stings or bites.
Mollusks: Cone snails and some species of octopus can release venomous saliva.
Plants: Plants like poison ivy, poison oak, poison hemlock, or deadly nightshade contain chemicals that can cause skin irritation or more severe symptoms upon contact.
Bacteria: Some bacteria produce toxins that can cause food poisoning or other illnesses.
Mammals: The platypus has venomous spurs on the hind legs of the males, and some species of shrews produce venomous saliva.
It's important to remember that many of these organisms are not aggressive and only use their toxins in self-defense or for predation. When encountering any potentially harmful species, it is advisable to maintain a respectful distance and avoid direct contact to stay safe.
