00:00:04.380 --> 00:00:07.050
<v 1>These little lobsters really know how to project.</v>

2
00:00:07.140 --> 00:00:10.380
You can hear them almost two miles away. Have a listen.

00:00:13.860 --> 00:00:17.700
French and US researchers whose work was published in scientific reports,

4
00:00:17.705 --> 00:00:21.300
used microphones to listen in on European spiny lobsters.

5
00:00:21.450 --> 00:00:25.050
The California Academy of Sciences says the lobsters create this odd,

6
00:00:25.050 --> 00:00:28.380
and let's face it, painful sound called antenna rasps.

7
00:00:29.370 --> 00:00:33.450
By rubbing a soft section of its antenna on a smooth file under its eyes,

8
00:00:33.540 --> 00:00:35.970
researchers recorded over 1500 sounds.

9
00:00:35.975 --> 00:00:40.590
From 24 spiny lobsters as deep as 328 feet off the coast of France,

10
00:00:40.680 --> 00:00:45.600
they found spiny lobsters could potentially be detected up to about 1,312

11
00:00:45.605 --> 00:00:48.150
feet. And believe that with little background noise,

12
00:00:48.210 --> 00:00:52.230
rasps from very large lobsters could be heard almost two miles away.

13
00:00:52.230 --> 00:00:52.980
Under water,

14
00:00:52.980 --> 00:00:56.730
researchers say the sea water's density allows sound to travel much farther than

15
00:00:56.730 --> 00:00:57.510
it would with air.

16
00:00:57.510 --> 00:01:02.190
They say spiny lobsters use antenna rasps to communicate and ward off predators.

17
00:01:02.790 --> 00:01:06.840
The findings could provide a non-invasive technique for detecting lobsters at

18
00:01:06.840 --> 00:01:09.510
far distances, helping with conservation efforts.
