Many arthropods bite or sting in order to immobilize their prey or deter potential predators as a defense mechanism. Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While ...
[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]
The deathstalker is one of the most dangerous species of scorpions. [10] [11] Its venom is a powerful mixture of neurotoxins, with a low lethal dose. [12]While a sting from this scorpion is extraordinarily painful, it normally would not kill a healthy adult human.

There has been much debate as to which arthropod group is most closely related to the Myriapoda. [20] Under the Mandibulata hypothesis, Myriapoda is the sister taxon to Pancrustacea , a group comprising the Crustacea and Hexapoda (insects and their close relatives).
The survival of diverse arthropods is essential to propagation of higher animals on the food chain, e.g. those species who prey upon the insectivores and other taxa that consume arthropods. Even if constant arthropod total biomass results after certain arthropod extinctions, the ecosystem stability is compromised by reduction in species numbers.

The effects suffered by bees from toxic chemicals that they encounter in the environment can be severe. These chemicals include various man-made compounds, such as insecticides and fertilizers , as well as a variety of naturally-occurring chemicals from plants, such as ethanol resulting from the fermentation of organic material.
