Noisy Eaters Are Cause of Mysterious Ocean Sounds

If noisy chewing bothers you, never date a sea urchin.

New Zealand scientists say they have confirmed that the spiny sea creatures are responsible for a mysterious, twice-daily uproar heard underwater.

The 20- to 30-decibel noise is caused by the spiny sea creatures' teeth scraping on reefs as the hungry starfish relatives feed on algae and invertebrates.

What's this?
Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

"We put some urchins in a tank and got them feeding on algae, then we recorded them. The noise they were producing caused spikes at certain frequencies."

in addition to loud, cattle-like slurping and munching, she couldn't spell or punctuate her way thru a soggy feed-bag.
