An invasive species is an organism, not necessarily an animal, but any organism, that is not native to an ecosystem, but somehow is introduced to it and often disrupts it.

I live in florida, where most people are aware of the many invasive species here, especially because the everglades are such a fragile ecosystem.
00:22
Most of our invasive species are phylum cordata.
00:25
We have a lot of frogs and reptiles that are invasive.
00:28
And one of the most problematic of those is the burmese python.
00:36
The carcass of a dead python who had once eaten an alligator and then exploded was found in the everglades suggesting that pythons are starting to go after alligators, which are one of their only predators left.
00:50
They have no natural predators here and they are wiping out native populations.
00:55
And they are of phylon cordata.
00:57
They are reptiles.
00:58
Another organism here is the iguanas, which are mostly eating plants, but the problem they pose is that they have no natural predators either, and they are rapidly multiplying.
01:12
I see an iguana probably every single day, and they're causing problems to humans, too, since they carry diseases and they're taking over.
01:21
Another organism here are the giant african land snails, one of the only non -cordates here that are invasive...
