Capable of being thrust out or extended, like body parts that can be pushed outward from the body.
Derived from Latin 'exserere' (to thrust out) plus the suffix '-ile' (capable of), following the pattern of similar capability words like 'flexible' and 'tensile'.
Some animals have exsertile parts that are absolute superstars of adaptation—snails can exsert their eyes on stalks to look around, and some fish can exsert their jaws way out to surprise prey!
