Spiny lobsters Raise an Undersea Racket That Can Be Heard Miles Away

May 27, 2020 By Liz Kimbrough Mongabay
European spiny lobsters create quite the rumble. By rubbing an antenna across its face, a spiny lobster can create a sound that might, under the right underwater conditions, be detectable up to 3 kilometers (1.9 miles) away. The sound, known as an antennal rasp, occurs when an extension of a lobster’s antennae moves across a rough patch under its eye. Lobsters likely make this sound for communication or to scare away predators. In a recently published study in Scientific Reports, researchers asked, how far does the sound of a rasp travel? And can these sounds be used in a non-invasive way to monitor lobster populations?
