The Lobster Conservatory includes information on the biology and conservation of lobsters. The majority can be applied to crayfish due to common ancestry and homology. Neural and tail anatomy provides an idea of the organization of the segmental ganglia in the tail of the crayfish. The second diagram on the page is a transverse section through ...
In the American lobster, endogenous morphine is found in the haemolymph and ventral nerve cord. In lobsters which have had a pereiopod (walking leg) cut off or been injected with the irritant lipopolysaccharide, the endogenous morphine levels initially increased by 24% for haemolymph and 48% for the nerve cord.

Let’s talk about the lobsters themselves first. They are crustaceans, related to crabs, shrimp, krill and a host of other marine invertebrates (animals without backbones) with exoskeletons.
The spiny lobster is eaten by various fish, octopuses and sea otters, but can defend itself with a loud noise produced by its antennae. The California spiny lobster is the subject of both commercial and recreational fishery in both Mexico and the United States, with sport fishermen using hoop nets and commercial fishermen using lobster traps.
While squat lobsters look like true lobsters, they are more closely related to hermit crabs. Instead of carrying shells on their backs, they squeeze their bodies into crevices and leave their claws exposed to defend themselves from predators or other squat lobsters.
The rules about the minimum and maximum sizes of lobsters that can be trapped off New England could soon become stricter, potentially bringing big changes to one of the most valuable seafood ...
Dalí had already introduced the lobster as an erotic symbol in his 1936 surrealist object “Lobster Telephone,” and the following year, Schiaparelli offered him a new kind of blank canvas ...
The inefficiency of the trapping system has inadvertently prevented the lobster population from being overfished. Lobsters can easily escape the trap, and will defend the trap against other lobsters because it is a source of food. An estimated 10% of lobsters that encounter a trap enter, and of those that enter 6% will be caught. [66]
