Death metal attracts sharks as it mimics "struggling fish"
by Rusty Blazenhoff from on (#49E4Q)
TIL: Sharks are attracted to the sound of death metal. Apparently, the "dense tones" of it mimics the "low frequencies of struggling fish." (Damn.)
In 2015, a Discovery Channel crew -- hoping to attract a large great white named "Joan of Shark" -- dropped a speaker underwater and played some.
Desperate to feature the 16-foot, 1.6 tonne shark in their documentary, they submerged a speaker to see if the shark would react. Unfortunately they didn't manage to attract Joan, but did catch the attention of two others, one of which was 12 feet long.
Sharks 'hear' by picking up vibrations from receptors on their bodies, meaning they can be attracted to the low-frequency vibrations of heavy music, which apparently sounds like struggling fish.
