Extinct Animals

mass extinction: When at least 50 % of the species on Earth go extinct within a relatively short amount of time.

A few species of lions and tigers have become extinct over the last 100 years. They include the Bali tiger, the Caspian tiger, the saber-tooth tiger, the Tasmanian tiger, and the Javan tiger.

Baisicly any animal that is already protected. The reason why they are protected is because people have noticed their numbers have segnificantly gone down like the giant panda,now its protected from being hunted and the hunter(s) will be greatly fined for doing so.

if grasses and shrubs is removed from the grass land eco-system then primary consumers would be secondary consumers.for example, removal of tress and vegetation will affects both land and water ecosystem as there will be no food for organisms

As it evolved in isolation it had no fear of predators and humans. Being a flightless bird it was easy prey for non-native species and humans. Also it is believed that their nesting grounds were destroyed as well.

The last passenger pigeon was named "Martha" and lived in the Cincinnati zoo until her death in 1914.

We need to con serve animals like deer and moose, and elk. But you can not kill more than you need.Butnot many, but we are taking away there habatats by tearingthem down. not many, but we are taking away there habatats by tearingthem down.

it isn't extinct, im joyed to say that there are still 25 among us

They say that there is no animal as big or bigger than the blue whale, although some people think that some dinosaurs could be bigger than it but no ones sure (mainly because they can just estimate the size of the dinosaur)

lysttrosaurus was a medium sized reptile with two short tusks, it is in a class called the dyconadonts which became extinct at the end of the triassic period, and may be an adept swimmer. it is a herbivore, and it's fossils are found even in remote places like antartica.

A mammoth is a big furry animal that existed many years ago. you would have seen this animal if you have ever watched the movie Ice Age. there is a mammoth in that movie. it doesn't look exactly like an elephant but they have some similarities like their eyes and trunks and more. they are like cousins. mammoths eat grass because mammoths are herbivores. herbivores are animals that only eat plants. many mammoths died because in their area, they didn't have grass but most people thought they were hunted until scientists proved them wrong. most people were wondering if they should clone the mammoths. There's Mammoth DNA found in the glaciers. some people think that with technology should they consider cloning a new mammoth to bring the species back from extinction. some other people think that they should not bring the mammoths back from extinction because there wont be many places for them to live since humans are building new buildings and houses.

Mammoths lived on grassy plains from the Arctic to the tropics. Their remains have been found in Europe, Asia, Africa, and North America. Different species lived in different areas, for example, the woolly mammoth lived in the tundra and the Columbian mammoth lived in temperate to tropical grasslands.

There are several different reasons why species become extinct. Sometimes extinctions are related to catastrophic global events such as the impact of a large comet or meteor, causing firestorms, great clouds of debris blotting out the sun, and so forth. Sometimes it is just a matter of natural selection as described by Darwin; species compete with other species, and some species lose the competition.

I'm a shark tooth collector, and the smallest principle megalodon tooth I've seen was 1.48' inches long and 1.12' inches wide. If you were to compare this tooth to a great white tooth of comparable size, that shark would be between 6"- 8" feet long.

The biggest type of shark is a Whale shark. It is over 40 feet long and only feeds on small fish. The other biggest shark is a megalodon which is extinct.

All animals including humans are part of some or the other ecology and there are many food chains in every ecology. For exaple tigers eat deers who eat grass which are in jungle etc. If tigers are killed there will be too many deers who will eat all the grass and small plants in the jungle and spread diseases as weak and old deers would have fallen pray to tigers and only healthy once would have survived. Having no grass will kill the jungle which will mean no rain therefore no water for drinking, farming etc. which will kill everybody in one way or the other. So if one animal is extinct it will leave a vacuum which is not possible to fill. Even if animals in one area are extinct it will affect ecologies world arround in one way or the other. That is why it is so imp to save every living thing on the planet from extinction ... or we may ourselves go extinct one day ... sooner than later.

I think that the natural causes of the extinction of animals and plants is a natural disaster.For example: volcanoes, earthquakes, plate movement, magnetic reversal, mudslides, floods, drought, global warming, etc.

I'm afraid you are not quite right there. Individual events such as single eruptions and mudslides have only local effects. Extinctions imply world-wide changes, usually of climate, but these can follow very large-scale, very long-term volcanic activity.

Earthquakes don't drive species into extinction - their only fatal effects on wildlife are local and generally from either resulting tsunamis or landslides.

I would say dormant - since the last estimated eruption was in the 18th century.

Since jaguars are endangered from a few things, we must help protect them. Because they are disappearing, we started to make it illegal to hunt or kill the jaguars. We have zoos and national parks. We have breeding programs, programs that breed and set them into the wild.

We could make a place were you cant hunt them at all. People could put fences up and block their path with wires on top. Millions of things we could do just to help. Start a donation for just jaguars. Give money to zoos to have them there. All sorts of endless ideas, the sky is the limit.

Another simple thing being done is researchers are finding wild jaguars and putting radio collars on them, doing this can tell them where, and what they have been doing. So that they can tell where to put a protected area for jaguars and other creatures.

The mega shark is the megaoldon shark may be extinct but 95% of the ocean is un-exslored.what if hes down there?

because of the interdependence of living things The extinction of one species or development of a new one often affect many others because of their interdependence in an ecosystem.

No extinction is as well documented as that of the New Zealand Moa (pronounced mo-ah). It was a large flightless bird of the order Dinornithiformes. Weighing up to 250Kg and 2.5 metres high, it was hunted to extinction by the Maoris by about 400 years ago. The Moa occupied the ecological niche in New Zealand of the antelope, rhinoceros and kangaroo and lived in habitats from forest to alpine tundra. They were abundant when the Maoris arrived in New Zealand about 1,000 years ago. Being so easy to catch and kill, only the best parts of the bird were eaten, the rest being discarded. One site alone shows evidence of 30,000 to 90,000 birds having been butchered over the period of Maori habitation. Dr Tim Flannery's book, "The Future Eaters" gives a good account of the extinction of the Moa and he quotes "Prodigious Birds" by Atholl Anderson as a "splendid work on the Moa".

Megalodon became extinct a little bit more than 2 million years ago.

Because before people didn't take care of our earth and animals don't like the litter so now help earth.If your'e talking about dinosaurs then here is the answer:They are extinct by weather and there are some dinosaurs still living such as bee's and butterflie's.
