Crayfish often find themselves in a conflicting situation where they are performing the highly motivated behavior of feeding when they suddenly receive a tail flip stimulus. Often, the crayfish will not perform a tail flip in this situation. This is because when a crayfish is actively feeding, the LGI itself is modulated by the behavior.
The caridoid escape reaction is an innate danger response in crustaceans such as lobsters and crayfish, which contracts abdominal flexions and sends the crustacean flying backward in the water. [21] Brachyura and species which have undergone carcinization have strongly bent and immobile tails, which prevent them from using this evasion strategy.
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. [5] Because all the hard parts are lost at each molt, the life span of mature spiny lobsters is uncertain; [5] they are thought to live for 50 years ...
