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 ...
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] [page needed]
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 species have wings. They are an extremely diverse group, with up to 10 million species. Arthropods are invertebrate animals with a chitinous exoskeleton, segmented bodies, and jointed legs. The phylum Arthropoda contains numerous taxonomic orders in over 20 classes.
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.
In a 2012 molecular study, von Reumont et al. challenge the monophyly of Vericrustacea: they present four versions of Pancrustacea cladogram (figures 1–4), and in all four figures Remipedia is a sister group to Hexapoda, and Branchiopoda is a sister group to (Remipedia + Hexapoda). Thus, their data strongly suggest that Branchiopoda is more ...
Eva Longoria (“Only Murders in the Building,” “Land of Women”) and Nicholas Galitzine (“The Idea of You”) are set to lead the voice cast of Studiocanal’s “Wings of Freedom,” a ...
