  4. Apr 15, 2022 · Arthropods comprise the largest group of living animals, including thousands of species that inhabit marine and terrestrial niches in the biosphere. Among the major groups of terrestrial arthropods, several classes contain venomous species, such as arachnids (scorpions and spiders), hymenopterans (ants, bees, and wasps), and chilopods (centipedes).

  5. We propose that, like non-human animals, humans have a distinct ectoparasite defence system that includes cutaneous sensory mechanisms, itch-generation mechanisms and grooming behaviours. The existence of adaptations for ectoparasite defence is supported by abundant evidence from non-human animals, as well as more recent evidence concerning human responses to ectoparasite cues.

This review presents the main species of venomous and poisonous arthropods, with commentary on the clinical manifestations provoked by the toxins and therapeutic measures used to treat human envenomations.
