A body layout that is the reverse of ours. An arthropod’s brains is in its head, but its nervous cord runs along its belly and its food passage (stomach, intestines, etc.) runs along its back. Since the brain (above the mouth) connects to the nervous cord (below the mouth), the brain actually surrounds the esophagus.

Arthropod head problem. Formation of anterior segments across arthropod taxa based on gene expression and neuroanatomical observations, [2] [3] Note the chelicera (Ch) and chelifore (Chf) arose from somite 1 and thus correspond to the first antenna (An/An1) of other arthropods. The (pan)arthropod head problem [4] is a long-standing zoological ...
Spiracle (arthropods) A spiracle or stigma is the opening in the exoskeletons of insects, myriapods, velvet worms and many arachnids to allow air to enter the trachea. [1] [2] [3] In the respiratory system of insects, the tracheal tubes primarily deliver oxygen directly into the animals' tissues. In most species the spiracles can be opened and ...
