Residents of Pacific Grove are complaining about a mysterious, low-frequency humming noise coming from Monterey Bay at night and since the beginning of summer night.
Could it be related to toadfish’s love songs calling their mates?
This weird and mysterious nighttime engine sound keeps Pacific Grove residents up at night since the beginning of summer. The disturbing hum emanates from the Monterey Bay and has baffled residents all summer long.
Similar to Hythe (UK), US biologists are actually thinking that these annoying noises are actually sex calls produced by lonesome male plainfin midshipman — or toadfish – trying to attract mates between May and September.
These rather small fish create this motor-like sound by using their strong muscles pressing against their balloon-like bladders about 6,000 times a minute resulting in a loud buzzing and disturbing noise.
But this explanation is only true for residents living nearby the ocean. Otherwise, the humming toadfish sounds may not be the answer to your mystery.
