The greatest numbers of exotic species are inadvertently distributed by shipping either attached to the hull or carried in the large volumes of ballast water. Introductions may also be deliberate.

However, many use the term to include native species as well (e.g., snakes may sometimes be considered exotic as pets even in places where they are found in the wild).
Why exotic species are harmful to ecosystem?
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
How do exotic species harm biodiversity?
Invasive alien species are animals, plants, fungi and microorganisms entered and established in the environment from outside of their natural habitat. They reproduce rapidly, out-compete native species for food, water and space, and are one of the main causes of global biodiversity loss.
What is the difference between exotic species and invasive species?
Exotic Species: An exotic species refers to a plant, animal or microorganism species, which is introduced into an area outside of its native range. Invasive Species: An invasive species refers to an exotic species whose introduction causes environmental and economic harm to the ecosystem.

Are exotic and invasive species the same?
Many people think that the words “invasive” and “exotic” are synonymous when in fact they are very different. Exotic simply means non-indigenous to an area, which is the opposite of native which means indigenous to an area. Invasive means tending to spread prolifically and undesirably/harmfully.
What is an exotic species?
Exotic species, which are also known as alien species, invasive species, non-indigenous species, and bioinvaders, are species of plants or animals that are growing in a nonnative environment. Alien species have been moved by humans to areas outside of their native ranges. Once transported, they become removed from the predators, parasites, and diseases that kept them in balance in their native environments. As a result of the loss of these controls, they often become pests in the areas into which they are introduced.
How much damage do rats do to the economy?
The economic damage caused by rats is huge. Rats alone do more than $19 billion of damage per year. Damage caused by alien insects cost $20 billion. Altogether, the more than 30,000 nonnative species in the United States cost the country $123 billion a year in economic losses, according to a June 12, 1999 report by Cornell University ecologists. In that report, David Pimentel of Cornell said that the United States has become the land of a billion rats.
Why is Hawaii so isolated from the rest of the world?
Because of this isolation, Hawaii originally had thousands of species that existed nowhere else on Earth. But it has suffered the highest rate of extinctions of any area of the United States and one of the highest rates anywhere in the world, with hundreds and possibly thousands of unique species already extinct. The tropical climate of Hawaii allows invasive plants and animals to thrive. Nonnative plants and animals frequently displace native species. Predation by nonnative rats, feral cats, dogs, and mongooses has led to the extinction of many species of birds. Habitat destruction by feral pigs has altered landscapes. To compound the problem, nonnative species are usually more aggressive at colonizing disturbed ground left behind by the feral pigs.
Why are invasive species so bad?

What are the changes that occur when an organism reproduces with a native species?
Other ecological changes may occur when the invading organisms reproduce with native species, possibly altering the gene pool. This may lead to hybridization and homogeneity, which reduces biodiversity, the primary element associated with an ecosystem's ability to adapt to natural or human-induced changes.
Why are fire ants feared?
The ants are feared because, when a nest is disturbed, the ants swarm over any nearby object, delivering multiple, painful stings to the intruder. However, the greatest economic impact of the imported fire ant comes from their attraction to electrical equipment.
How do invading species affect the ecosystem?
Invading species can cause complex changes within the structure and function of their new ecosystem. Their presence can lead to the restructuring of established food webs, the importation of new diseases to the new surroundings, and competition with indigenous organisms for space and food. Other ecological changes may occur when the invading organisms reproduce with native species, possibly altering the gene pool. This may lead to hybridization and homogeneity, which reduces biodiversity, the primary element associated with an ecosystem's ability to adapt to natural or human-induced changes.
