Socialization Habits
Scientists Donald C. Behringer, Jeffrey D. Shields, and Mark J. Butler conducted an experiment off the coast of the Caribbean in 2006. Their study consisted of underwater surveys of juvenile lobsters in their shared dens. This specific species of lobster is particularly social and was typically observed sharing dens when sleeping. In their experiment in the lab the lobsters were given the chance between an empty den and a den with an infected lobster. The results showed that healthy lobsters preferred the empty den compared to the den with the diseased lobster. However, when the diseased lobsters were given the choice between the two dens, they did not discriminate. Lobsters that became infected with the PaV1 virus started to show symptoms at six weeks and became fully infected at eight weeks. Most of the healthy lobsters avoided the inoculated lobsters at four weeks. All of the healthy lobsters avoided the sick lobsters at six and eight week marks. The PaV1 virus that infected these lobsters was the first naturally occurring viral pathogen for any species of lobster and it has significant effects on lobster ecology.

V-Notch Practice
The American Lobsters conservation status is currently filed as "Least Concern." The V-Notch practice is standard among almost all Lobster fishermen along the East Coast. A small V shaped notch is made on the tail flipper second from the left to signal that the female lobster is egg bearing. This important practice ensures that lobsters don't go extinct, and the species fitness maintains high. In 2000 over 80% of female, egg bearing lobsters were notched. This practice became a law in 2003 ensuring that populations would not dip too low.

Genome
The genetic makeup of the American Lobster consists of neurotransmitters, receptors and deep integration between the immune system and the neural system. These connections create an immense amount of awareness and sensitivity in American Lobsters. They also have a long list of adaptations that help the to survive all the way on the ocean floor. Their receptors create a way for them to find food even through high pressure, low temperatures and lack of sunlight.
