A lobster’s most acute sense is its sense of smell. A smaller pair of two-pronged antennae, called [[antennule]]s, contains hundreds of [[chemical receptor]]s that give lobsters most of their hunting and socializing skills. A lobster’s brain consists of several [[nerve ganglion]]s strung together, and nearly half of their volume is dedicated to processing the signals from the antennules. Lobsters use their sense of smell to identify each other as individuals as well as to pick up pheromonal signals and track down food.

American lobsters’ bladders are in their heads, and they urinate directly in front of their faces. This stream of urine mixes with the outflow from the gill chambers and is carried ahead of the lobster. Thus, lobsters literally have urinating competitions. They send messages like ‘Remember me? I beat you up last night,’ or, ‘Want to have sex? I’m about to get undressed,’ by urinating in each other’s faces. The urine of a dominant male lobster exudes a level of confidence that is deeply attractive to female lobsters.<ref> The Secret Life of Lobsters, by Trevor Corson, pub.
