The second diagram on the page is a transverse section through the tail that highlights the positions of the LGI, MGI and non-giant neurons. At the bottom of the page it also has diagrams of the tail flips caused by stimulation of the LGI (on the left half of the diagram) and the MGI (on the right half of the diagram).
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]
Caught lobsters are graded as new-shell, hard-shell, or old-shell. Because lobsters that have recently shed their shells are the most delicate, an inverse relationship exists between the price of American lobster and its flavor.

Female California spiny lobsters reach sexual maturity at a length of 65–69 millimeters (2.6–2.7 in), which is typically at an age of 5–9 years; males are sexually mature after 3–6 years.

When a gravid female approaches a male territory, he will grunt, moan and growl, in respective order, to signal her of his presence and to attract and induce her into becoming ripe for spawning.
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 ...
