Invasive species

Florida has a numerous amount of invasive species. A widly seen one is the Iguana they can reach lenghts of 3-5 feet. A male iguana can reach up to six feet. Iguanas are commonly seen in tropical enviorments such as the keys. All the iguanas that got here where once former pets that pet keepers let go due to having no desire to keep them because of there size. Iguanas origanally come from Central and South America. If they get to big instead of releasing it sell it to a store or person.

Another invasive specie is the Butterfly Peacock Bass. The where introduced to south florida in 1984 by The Game and Wildlife commision.They are from south America. Thousands were released to control the exotic fish population. Those exotic species are the spotted tilapia and the oscar. Male Peacock Bass will have a huge hump on there head. Peacock Bass cannot survive cold weather and due the 2010 freeze the population has dropped dramatically. Only time can get the population back up to the right amount.

The Snakehead is also another invasive specie. What makes the snake head worse than all the other species is that they will eat other fish nearly their own size. Every body of water is perfect for the snake heads even in low oxygenated water they can come up for air. They have a gland behind their gill plate which they then are able to breath air. Snakeheads were brought to the United States all the way from Asia. They Are a typical Asian dish. They were released and the population is on the rise. If you catch one of them you will have to kill it.
