what are the major differences between the pig and cattle based on their external anatomy?

Pigs and cattle have distinct external anatomical features. Pigs typically have a more elongated, rounded body with a flat snout, short legs, and a tail that is curly or straight. In contrast, cattle possess a larger, more robust body with a prominent hump on the back (in some breeds), long legs, and a broad, flat face. Additionally, cattle have larger, more prominent ears and often exhibit horns, whereas pigs lack horns and have a more compact head structure.
