noun / verb
turtle
TUR-tul/ˈtɜːrtl/
A reptile protected by a hard shell.
The turtle rests on a log with its head and webbed feet extended.

Etymology
French tortue supplied a name used in English first for marine tortoises, then extended to land tortoises. The French word's deeper origin is unknown.
In context
A turtle's shell is much more than just armor. It is actually part of its skeleton. When danger approaches, many turtles can retreat into their shells for protection.
