00:00:06,906 --> 00:00:13,747
In the waters of the western Atlantic 
and Caribbean a voracious alien predator

2
00:00:13,847 --> 00:00:19,386
has taken hold. We have never before seen 
a marine invasion of this magnitude or scale.

3
00:00:19,486 --> 00:00:25,458
Lionfish are indigenous to the 
Indo-Pacific. They've evolved over many

4
00:00:25,558 --> 00:00:29,362
thousands of years in a complicated 
system where everything had had time to work

5
00:00:29,462 --> 00:00:37,570
out its place and its controlling 
mechanisms. Not so in the Atlantic where

6
00:00:37,670 --> 00:00:43,376
this invasive species is a major threat 
to biodiversity and the health of

7
00:00:43,476 --> 00:00:50,316
already stressed coral reef ecosystems. 
The biggest concern we have is lion fish

8
00:00:50,417 --> 00:00:56,456
predation on other marine life. They are 
a voracious gluttonous feeder they're an

9
00:00:56,556 --> 00:01:01,061
ambush predator and they're very 
uniquely camouflaged so they can sneak

10
00:01:01,161 --> 00:01:07,200
up very close to their prey and our prey 
here in this range have not evolved with

11
00:01:07,300 --> 00:01:13,840
lionfish and don't see them as a 
predator. One of the key findings of the

12
00:01:13,940 --> 00:01:17,544
research that we've been doing here in 
the Bahamas is that lionfish have likely

13
00:01:17,644 --> 00:01:22,215
reduced fish populations on many of 
these reefs by up to ninety percent in

14
00:01:22,315 --> 00:01:28,988
the last four years. It's a free-for-all 
for lionfish right now no predators, lots

15
00:01:29,089 --> 00:01:31,458
of food - it's a kid in a candy store.

16
00:01:31,558 --> 00:01:35,558
The million-dollar question is what are we going to do about this?
