Animal Pain

Animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore do not experience suffering, say most researchers.

Vertebrates with spines have much more advanced nervous systems and can feel real pain and suffering.

The research regarding whether or not lobsters feel pain is still inconclusive. The hiss that sounds when crustaceans hit the boiling water is not a scream. They do not have vocal cords.

Interesting Animal Numbers

A swan has over 25,000 feathers in its body. Snails have 14175 teeth laid along 135 rows on their tongue. The North Atlantic right whale's testes account for around 1% of its total body weight, and each of them can weigh over a thousand pounds. Africa's Nile crocodile can measure twenty feet long and weigh two thousand pounds. A horse has sixteen muscles in each ear, which allows it to rotate its ears a full 180 degrees.
