 | | PENTASTOMIDA [Pentastomida], tongue worms, small phylum of fewer than 100 species of parasites living in the upper respiratory passages of reptiles, and occasionally of birds and mammals. |
 | | They are closely related to arthropods, but zoologists disagree as to their exact placement in that phylum. |
 | | When the intermediate host, in turn, is eaten, the larvae migrate to the respiratory passages of the final host, where they take up permanent residence and mature. |
