Measurements of the semicircular canals, the mechanism for balance inside the ear, showed that Archaeopteryx ( pronounced ar-kee-OP-tur-ix ) had the " neurological and structural adaptations necessary for flight, " the scientists concluded.

The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consonant with its habits, as in the remoras that ride attached to sharks and other fishes.

A "'plastron "'is a type of structural adaptation occurring among some aquatic arthropods ( primarily insects ), a form of inorganic gill which holds a thin film of atmospheric oxygen in an area with small openings called spiracles that connect to the tracheal system.

In 1953 he worked on the concept of " ancient deep-water " ( primitive teleosts which evolved early and dominate the demersal to abysso-and bathypelagic faunas and whose structural adaptation to their habitat include eye and swim bladder modifications and proliferation of light organs e . g.

"Spinosaurus " sails were unusual, although other dinosaurs, namely the ornithopod " Ouranosaurus ", which lived a few million years earlier in the same general region as " Spinosaurus ", and the South American sauropod " Amargasaurus, " might have developed similar structural adaptations of their vertebrae.
