The subphylum Hexapoda (from Greek for 'six legs') or hexapods comprises the largest clade of arthropods and includes most of the extant arthropod species. It includes the crown group class Insecta (true insects), as well as the much smaller clade Entognatha, which includes three classes of wingless arthropods that were once considered insects: Collembola (springtails), Protura (coneheads) and ...
The Entognatha are a class of wingless and ametabolous arthropods, which, together with the insects, makes up the subphylum Hexapoda. [1] [2] Their mouthparts are entognathous, meaning that they are retracted within the head, unlike the insects. [1] Entognatha are apterous, meaning that they lack wings.
Some evidence indicates the Protura are basal to all other hexapods, [6] although not all researchers consider them Hexapoda, rendering the monophyly of Hexapoda unsettled. [7] Uniquely among hexapods, proturans show anamorphic development, whereby body segments are added during moults. [8] There are close to 800 species, described in seven ...
Hexapodidae is a family of crabs, the only family in the superfamily Hexapodoidea. [1] It has traditionally been treated as a subfamily of the family Goneplacidae, [2] and was originally described as a subfamily of Pinnotheridae.

Carnivores have chelicerae that tear and crush prey, whereas herbivores can have chelicerae that are modified for piercing and sucking (as do parasitic species). In sea spiders, the chelicerae (also known as chelifores) are short and chelate and are positioned on either side of the base of the proboscis or sometimes vestigial or absent.
Feel free to go wild with the spice mix; swap in za'atar and sprinkle the chickpeas over creamy hummus or try curry powder instead and serve the chickpeas over Greek yogurt with cilantro and ...
Predators that eat poisonous butterflies and moths may vomit violently, learning not to eat insects with similar markings; this is the basis of Müllerian mimicry. [143] Some ground beetles of the family Carabidae actively defend themselves, spraying chemicals from their abdomen with great accuracy, to repel predators.
