The hooded pitohui.The neurotoxin homobatrachotoxin on the birds' skin and feathers causes numbness and tingling on contact.. The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.
[1] [2] They are often distinguished from poisonous animals, which instead passively deliver their toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested. [1] [2] [3] The only difference between venomous animals and poisonous animals is how they deliver the toxins. [3]
Bombardier beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—which are most notable for the defense mechanism that gives them their name: when disturbed, they eject a hot noxious chemical spray from the tip of the abdomen with a popping sound.
Therefore, they disrupt the victim's nervous system, making them much more effective. Within the frogs themselves, the toxins are accumulated and delivered through small, specialized transport proteins. [65] The Golden poison frog (Phyllobates terribilis) is among the species of poison frogs that have potential significance to medical research.
Aposematism is the advertising by an animal, whether terrestrial or marine, to potential predators that it is not worth attacking or eating. [1] This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom , foul taste or smell, sharp spines, or aggressive nature.
The seeds are mildly poisonous, containing a small amount of amygdalin, a cyanogenic glycoside. [13] The quantity contained in the seeds of a single apple is usually not enough to be dangerous to humans, but it is possible to ingest enough seeds to provide a fatal dose.

Bacteria have a rudimentary immune system in the form of enzymes that protect against viral infections. Other basic immune mechanisms evolved in ancient plants and animals and remain in their modern descendants. These mechanisms include phagocytosis, antimicrobial peptides called defensins, and the complement system.
An example of poison ingestion derives from the poison dart frog. They get a deadly chemical called lipophilic alkaloid from consuming a poisonous food in the rainforest . They are immune to the poison and they secrete it through their skin as a defense mechanism against predators.
