Spiders hatch in the spring or fall. The slightest breeze will carry them away in the air like a parachute. Pigs weigh about two and a half pounds at birth, and usually double their weight the first week. Adult pigs are called hogs. Hogs belong to the pig family called Suidae .
Hogs have thick skin and no sweat glands to serve as a cooling system.
They wallow in the mud to keep cool. The hog's snout has a broad, leathery pad that includes the nostrils. The snout is very sensitive. Hogs often use their snouts to dig for vegetable roots, one of their favorite foods. Hogs have four toes on each foot.
