Wet welcome
Wet welcome Squirting urine at others is acceptable behaviour
if you're a lobster. Researchers have discovered that lobsters
greet each other by squirting urine. This behaviour appears to help
them to both avoid fights and select mates. Scientists have long
wondered why many marine animals have bladders to store urine when
they could just allow it to leak out into the water. To discover
the answer, researchers glued catheters onto lobsters to measure
the animals' urine release. Their findings showed that lobsters do
not urinate when predators may be nearby, but that when two males
meet, their urine carries a record of who is the boss. As well,
males and females squirt urine at each other before choosing
mates. MARCH 20, 1999, P. 20
