name me 3animals that someone got to the u.s. from another location? how they got here and from where?

Question

3animals that somehow got to the u.s.? how they got here? from where they came? are they dangerous to their new enviroment?

Answer 1

Since everyone else is going with easier answers, how about these less commonly known animals:

1) Lionfish - normally found in the South Pacific. These fish were brought over to be put into private collections. However, after Hurricane Andrew hit south Florida, some of these fish were released into the wild. They are extremely dangerous since there is no current creature that can predate upon this fish due to its toxicity and the lionfish can practically eat any fish that crosses its path.

2) Zebra mussels - normally foundin the Black, Caspian, and Azov Seas. The main culprit of their delivery is incidental delivey through ballast water transference. They are voracious filtering bivalves which can each move a quart of water in one day, which is a higher rate than most other bivalve filter feeders. With this filtering capacity, the high level of fecundity and no known predator, they can easily diminish planktonic waters within weeks, thus hindering the chances of other invertebrates to go on. Furthermore, they have become a nuisance with local industries near the waterways since they can be commonly found in piping and tubes, restricting water flow and adding to their propagation rate
Zebra mussels have reduced populations of native phyto- and zooplankton as well as planktonic larvae of fish and other mollusks.

3) Pythons - commonly found in Central and South American rain forests. They have become a popular type of exotic pet. The problem with them is that many owners that are unable to properly care for these giant snakes release them into the wild. Pythons don't really have any natural predators in America. They have an almost unbiased feeding regimen when they need to eat. Their size and stalking strategy gives them a major advantage in many marsh and swamp land areas, especially in the Everglades. There was even a story recently where a python was found dead after splitting in half - as it attempted to digest an almost full grown alligator.

More than most times, any introduced species into a new environment does not bode well for the native fauna and flora, not only here but anywhere else in the world for that matter.

Answer 2

1) Earthworms: There were originally no native species of earthworms in North America. The Europeans used to use soil and rocks for ballast in their ships, and when they got to the shores of the St.Lawrence river, they would dump the soil out while they docked. Teh earthworms spread all across North America and are now found almost over its entire surface. Earthworms have shown to be beneficial to this new land, they aerate the soil, and provide food for many creatures. They do however decompose far too quickly in this region, which does reduce the fertility of our forests, but it seems that the trees have adapted to this and are doing fine.

2) Asian Longhorn Beetles: These borers are commonly associated to live inside wood. When items are imported from Asia on wood packing crates and pallets, they sometimes contain travelers. Sometimes these beetles would come over as eggs, and other times as larvae embedded in the wood. There are also documented cases of very large black beetles emerging from the arm rests of people's chairs or right out of their finished tables. They form chambers in wood and can go undetected, wailting to emerge once they get here.........the Trojan horse of the insect world.........hahaha. These insects are quite disasterous to this new unexpecting environment. These beetles have escaped their natural specific predators, and are now completely destoying harwood forests all across the country.

3) The Norway Rat: Probably the most adaptable and most cosmopolitain mammal in the world. These clever and inventive creatures would stow away on ships leaving harbors in Europe and tavelled all around the world as stow aways. Now they can be found on every continent, and have adapted to all of them. These creatures are not really a problem here, because they are rodents, and are the bottom of the food chain which means that the larger predators here are better fed. They do however cause significant crop damage in certain areas, which affects us and not the natural world...............so who cares hahaha. They are also the intermediate host for several feline parasites, so they can cause complications to wild cat populations.........but there have been no documented cases of this.

Answer 3

1. Horses were brought to the US by Spanish explorers. And actually, the car (the horseless carriage) was invented because of the pollution caused by horses in the streets. Can you say, road apples?

2. Pigs are native to Eurasia and were also brought to the new world the the Spanish. Wild pigs are reported primarily in the southeastern United States, California, and Hawaii; despite their status as game in most areas, they pose serious threats to native plant communities and rare plant species by their foraging and digging.

3. Ring-necked Pheasant from Asia and Europe .They are native to Asia but have been widely introduced elsewhere, where they are bred to be hunted and are shot in great numbers.

Answer 4

Gypsy moth (Lymantria dispar) - Native to Europe, introduced to North America in 1868 or 1869 in the Boston area by E. Leopold Trouvelot (he was trying to raise them and get silk from their coccoons and they got out). Now a major pest across North America. Although their favourite hosts are oak and aspen poplar, they will eat any of about 200 species of trees and shrubs, and develop into massive outbreaks. Have cost billions of dollars in economic losses, and untold havoc to the ecosystems they have invaded.

European starling (Sturnis vulgaris) - Native to Eurasia and North Africa. Introduced to North America in 1890 by Eugene Schieffelin, who released approximately 60 birds in Central Park, New York because the birds were mentioned in the works of William Shakespeare. Today there are an estimated 200 million starlings across North America. This adaptable and omnivorous bird is very aggressive, and will sometimes drive off native birds such as bluebirds, swallows and woodpeckers. In many regions it is legal to kill starlings and some areas even pay a bounty. There's an interesting video showing a flock of starlings nearly destroying a tree with their weight. http://www.youtube.com/watch?v=WfkexGdmmQk

Nutria or coypu (Myocastor coypus) - Native to South America. Introduced into the Gulf of Mexico near New Orleans in the early 1930's by gullible souls who believed nutria fur would be "the next mink". Also released into other areas such as Texas to control aquatic vegetation growth. Rapid reproduction rates have led to overpopulation in many areas, and loss of vegetative cover in wetland habitats used by native mammals, birds, reptiles and amphibians. Now well established in more than 40 states, they also eat crops, and carry a number of parasites and diseases that can affect humans, including the nematode Strongyloides myopotami, or 'nutria itch' which can cause a severe rash when the larval worms burrow into a human wading in infested waters.

Answer 5

Chinese Mitten Crab-from Asia, possibly intentionally introduced, pest
Fire Ant- from South America, pushing out native species and potentially dangerous in large numbers
mongoose- eats bird eggs in Hawaii, from India, introduced to eat tree snake

Answer 6

1. The Horse
Spaniards brought the horse to this continent when they slaughtered - I mean decided to help - the Aztecs.

2. The Longhorn
The Spaniards also brought this animal when they enslaved - I mean gave jobs to - the Aztecs.

3. I don't have a 3rd animal.

Answer 7

Wild ponies of Assateague, they think they were stranded by Spanish ships that wrecked.

Sorry can only think of one right now.
There are these walking fish? that have somehow gotten into the us and there is actually a bounty for them because they are very destructive to our natural environment. Can't think of the name.

Answer 8

In mainland US, large number of birds were brought in by European settlers. The common ones among them are:
European Starlings
House Sparrow
Parakeets (though mostly restricted to LA and neighbouring counties)

Answer 9

1- Christoffer Columbus
2- The French
3- Bush family
Yes, they are all dangerous.
