It is dominated by mollusks (especially mussels), echinoderms and polychaetes, although a wide range of other prey items may be eaten, including other crustaceans, brittle stars and cnidarians.
It only requires a few bacterial cells to cause death of otherwise healthy lobsters.
Despite the rarity of strangely colored lobsters, many more of them are reported being caught.
It is unclear as to whether this is an artifact of social media making reporting and sharing more accessible, or if it is due to a drop in predator populations.
These cause a loss of surface area around the gills, and the lobster eventually asphyxiates.Lobsters use scents to communicate what and where they are, and those scents are in the urine.They project long plumes of urine 1–2 meters (3 ft 3 in–6 ft 7 in) in front of them, and do so when they detect a rival or a potential mate in the area.Its closest relative is the European lobster Homarus gammarus, which can be distinguished by its coloration and the lack of spines on the underside of the rostrum.American lobsters are usually bluish green to brown with red spines, but several color variations have been observed.Paramoebiasis is strongly suspected to play a prominent role in the rapid die-off of American lobsters in Long Island Sound that occurred in the summer of 1999.
