If twisted into a rope, some spiders' thread would be stronger than iron wire. Mother spiders make a silken sac, in which they lay their eggs. They may lay from one to 3,000 eggs at a time. 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.
