The ostrich is omnivorous and not only dines on insects, snakes, rodents, roots, and most vegetation but also swallows wood, shells, stones, sticks, and almost any small, brightly colored object.
In size, insects vary from beetles that are small enough to get through the eye of a needle to curious “walking sticks” that measure more than 30 cm (1 ft) in length.
How did this tiny animal (she is not an insect, which only has six legs to the spider’s eight) “discover” and “evolve” oil glands in her “feet,” preventing her from sticking to her own glue?
