Could anyone help me identify a fish by the sound it produces?
Kayakers observing bioluminescence (obviously at night) in a bay in eastern Puerto Rico are
reporting fairly loud sounds they hear from their kayaks as "sounding like a squeaky door being
opened and closed" that gets louder as the organism (presumably a fish or school of fish)
approaches, and due to Doppler effects, softer after it passes by. The kayak transmits the sound
from the water.
If anyone cares to speculate on the species of fish, I'd be interested in knowing what it might be.
