As arthropods, lobsters have not achieved the nervous system development of cephalopod molluscs, nor do they have the advantages of extraordinary eyesight. They do, however, exhibit three remarkable evolutionary advances that have led to their great success: an exoskeleton: a strong, lightweight, form-fitted external covering and support, striated muscle: a quick, strong, lightweight form of muscle that makes rapid movement and flight possible, and articulation: the ability to bend appendeges at specific points.

Lobsters typically eat live food, consisting of fish, mollusks, other crustaceans, worms, and some plant life. Occasionally, they will scavenge if necessary, and may resort to cannibalism

Catching



Lobsters are caught using baited, one-way traps with a color-coded marker buoy to mark cages. Lobster is fished in water between 1 and 500 fathoms, although some lobsters live at 2,000 fathoms. Cages are of plastic-coated galvanized steel or wood. A lobster fisher may tend between 10 and 2,000 traps. Around the year 2000, due to overfishing of some species and high demand lobster farming became more prevalent. As of 2008, no lobster farming operation has achieved commercial success.

Capacity for pain



Due to the ambiguous nature of suffering

, the issue of lobster pain may be approached using an argument by analogy — that lobsters are similar to human biology or that behavior warrants assumptions that lobsters can feel pain.

The Norwegian Scientific Committee for Food Safety tentatively concluded that "it is unlikely that [lobsters] can feel pain," though they note that "there is apparently a paucity of exact knowledge on sentience in crustaceans, and more research is needed." This conclusion is based on the lobster's simple nervous system. The report assumes that the violent reaction of lobsters to boiling water is a reflex to noxious stimuli.

However, review by the Scottish animal rights
Animal rights
Animal rights, also referred to as animal liberation, is the idea that the most basic interests of animals should be afforded the same consideration as the similar interests of humans...

 group Advocate for Animals released in the same year reported that "scientific evidence ... strongly suggests that there is a potential for [lobsters] to experience pain and suffering," primarily because lobsters (and other decapod crustaceans) "have opioid receptors and respond to opioids (analgesics such as morphine) in a similar way to vertebrates," indicating that lobsters' reaction to injury changes when painkillers are applied. The similarities in lobsters' and vertebrates' stress systems and behavioral responses to noxious stimuli were given as additional evidence for their capacity for pain.

A 2007 study at Queen's University, Belfast, suggested that crustaceans do feel pain. In the experiment, when the antennae of prawns were rubbed with sodium hydroxide or acetic acid, the animals showed increased grooming of the afflicted area and rubbed it more against the side of the tank. Moreover, this reaction was inhibited by a local anesthetic, even though control prawns treated with only anesthetic did not show reduced activity. Professor Robert Elwood, who headed the study, argues that sensing pain is crucial to prawn survival, because it encourages them to avoid damaging behaviors. Some scientists responded, saying the rubbing may reflect an attempt to clean the affected area.

In a subsequent 2009 study, Prof. Elwood and Mirjam Appel showed that hermit crabs make motivational tradeoffs between shocks and the quality of the shells they inhabit. In particular, as crabs are shocked more intensely, they become increasingly willing to leave their current shells for new shells, and they spend less time deciding whether to enter those new shells. Moreover, because the researchers did not offer the new shells until after the electrical stimulation had ended, the change in motivational behavior was the result of memory of the noxious event, not an immediate reflex.

Opioids

s are neurochemicals that moderate pain by interacting with opiate receptors. Opioid peptides and opiate receptors occur naturally in crustaceans, and although The Norwegian Scientific Committee for Food Safety claims that “at present no certain conclusion can be drawn,” some have interpreted their presence as an indication that lobsters may be able to experience pain. The aforementioned Scottish paper holds that lobsters' opioids may "mediate pain in the same way" as in vertebrates.

, an opioid receptor antagonist, may affect a related species of crustacean (Chasmagnathus granulatus) in much the same way they affect vertebrates: injections of morphine into crabs produced a dose-dependent reduction of their defensive response to an electric shock. (However, the attenuated defensive response could originate from either the analgesic or sedative properties of morphine, or both) These findings have been replicated for other invertebrate species, but similar data is not yet available for lobsters.

Animal welfare issues


The most common way of killing a lobster is by placing it, live, in boiling water, or by splitting: severing the body in half, lengthwise.

The boiling method (also used to kill crabs, crayfish and shrimp) is controversial because some believe that the lobster suffers. The practice is illegal in some places, such as in Reggio Emilia
