What the Shell? Cracking the Lobster's Mysteries

They are the "cockroaches of the sea," a prehistoric bully that has survived since the Jurassic period, yet a single line from the TV show Friends convinced millions that lobsters are romantic creatures that mate for life. In this episode of Gastropod, hosts Cynthia Graber and Nicola Twilley crack open the shell of the American lobster to separate pop-culture myth from biological reality, tracing its journey from a despised prison food to a luxury delicacy, and exploring the bizarre biology that makes it a subject of scientific wonder.

The Myth of the Romantic Lobster

The episode begins by dismantling Phoebe Buffay's famous claim that lobsters are soulmates. According to Trevor Corson, author of The Secret Life of Lobsters, the truth is far less romantic and far more strategic. The male lobster is a belligerent bully who is only interested in fighting, not romance. The females, however, want his strong genes. Their solution is a kind of chemical manipulation: they produce an aphrodisiac in their urine, which they squirt from nozzles on their faces directly at the male. This "date rape drug" calms the aggressive male down long enough for the female to have her way with him. Furthermore, the females in a neighborhood form a "sisterhood," taking turns to seduce the alpha male. The lobster’s sex life is not a tale of lifelong love, but of female-driven chemical coercion
