Lobsters

Lobsters are sentient beings capable of experiencing pain just like dogs, pigs, chickens and humans. Not having an autonomic nervous system that puts them into shock, when they are "damaged" they could suffer more.

They exhibit complex behavior and have a considerable capacity for learning. If these animals are not removed from their natural habitat, they can live for decades or even more than 150 years. They recognize other lobsters, remember their past knowledge, and have elaborate courtship rituals. They carry their young for nine months. Sometimes they walk hand in hand, the older lobsters leading the younger ones. Researchers studying lobsters say their intelligence rivals that of octopuses, long considered the world's smartest invertebrate.

Used as food, they are frequently subject to one of the most cruel fates an animal can know. Before being killed, in the open (transport, factories, grocery store displays), they are slowly asphyxiated and their ordeal can last for several days. The buildup of toxins in their bodies causes them pain. Normally solitary, they are stacked on top of each other.

Even when locked in tanks (tiny and unsuitable aquariums that cannot guarantee adequate conditions), these crustaceans, which can travel 160 kilometers per year in nature, are reduced to immobility and their claws, which they use to burrow, feed and communicate using complex signals, are tied tightly to prevent mutilating each other as the extreme confinement drives them mad.

Being immersed in a pot of boiling water while still being conscious inflicts on these sentient beings as much pain as you can imagine and they show it by frantically scratching the sides of the pot for up to a minute before dying. They are often dismembered alive or cut their pincers and legs without administering pain treatment.
