We are terrible neighbors. Ask the dolphins.
The world’s oceans are getting noisier, humming with the near-constant sounds of ship engines, seafloor mining, and oil and gas exploration. Now, a new study published in the journal Biology Letters has found that dolphins are being forced to simplify their calls in order to be heard over the noise.
Dolphins are highly social animals and use their calls to stay together as a group, talk as they feed, and call out their names when they meet new members of their species. Each animal has a distinctive whistle, which typically uses complex sound patterns with variations in pitch and frequency.
It’s not just our planet.
