Transcript
O’NEILL: By the way, what does an oyster reef sound like? A few years ago, our colleague Sophia Pandelidis reported on how reef soundscapes may help baby oysters settle in a safe place. Here’s a taste.
SNAPPING SHRIMP SOUNDS
PANDELIDIS: Snapping shrimp, which hide in the nooks and crannies of reefs, dominate this underwater orchestra.
SNAPPING SHRIMP CONTINUES
PANDELIDIS: They create air bubbles that pop by snapping their claws together at roughly 60 miles per hour, making them one of the fastest moving creatures in the animal kingdom.
And while researchers say the shrimp take first chair in the underwater orchestra, other creatures add richness to the symphony.
FISH SOUNDS
PANDELIDIS: Fish that purr, grunt, whoop, and even honk make up the brass section.
FISH SOUNDS
And grazing urchins, which scrape algae off rocks with their teeth, bring in the percussion.
GRAZING URCHIN SOUNDS
