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 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.
S. heros is found in northern Mexico and the southwestern United States, from New Mexico and Arizona in the west to Arkansas, Missouri, and Louisiana in the east. Although this species is commonly referred to as the "giant desert centipede" because of its presence in the Sonoran and Chihuahuan Deserts, and other arid and semi-arid habitats, S. heros is also found in rocky woodland areas, such ...
Arthropod eyes Head of a wasp with three ocelli (center), and compound eyes at the left and right. Most arthropods have sophisticated visual systems that include one or more usually both of compound eyes and pigment-cup ocelli ("little eyes"). In most cases, ocelli are only capable of detecting the direction from which light is coming, using ...

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).
