Historical Examples

  • No tracheate Crustacea are known, but some terrestrial Isopoda develop pulmonary in-sinkings of the integument.

    Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 6


  • Hexapoda: tracheate arthropods with head, thorax and abdomen distinct, and only six legs in the adult stage: the true insects.

  • The present tracheal respiration of the Tracheata developed at a later period out of respiration through the “tracheate gills.”

  • If the ancestor of the Insecta was, as seems possible, tracheate, this fact alone would rule out the trilobites.
