Among these extinct animals are the West African black rhinoceros, the baiji white dolphin, the Tasmanian tiger, the dodo, and Stellers sea cow. There are six main reasons why species now become extinct: Habitat loss.
Wild animals such as pandas and elephants are likely to become extinct as soon as 2025. Could you imagine by the time you may have started a family it is a possibility that your children will never see a panda or elephant?
Answer and Explanation: The Tecopa pupfish is one of the first animals that became extinct. The Tecopa pupfish was found in the hot spring of the Mojave desert.
Oldest Living Marine Animals: Bowhead Whales
The result is longer lives and less tissue damage. As a result, bowheads live well into their hundreds. According to researchers, the current record holder lived for 211 years.
The Dodo is a lesson in extinction. Found by Dutch soldiers around 1600 on an island in the Indian Ocean, the Dodo became extinct less than 80 years later because of deforestation, hunting, and destruction of their nests by animals brought to the island by the Dutch.
The rarest animal in the world is the vaquita (Phocoena sinus). It is a kind of critically endangered porpoise that only lives in the furthest north-western corner of the Gulf of California in Mexico.
For approximately 120 million years—from the Carboniferous to the middle Triassic periods—terrestrial life was dominated by the pelycosaurs, archosaurs, and therapsids (the so-called "mammal-like reptiles") that preceded the dinosaurs.
Woolly Mammoth
They were covered in fur and their curved tusks could easily be up to 5 metres long! The Woolly Mammoth eventually disappeared 10,000 years ago through a combination of hunting by humans and the disappearance of its habitat through climate change.
Estimates of sponge longevity vary quite a bit, but are often in the thousands of years. One study in the journal Aging Research Reviews notes a deep-sea sponge from the species Monorhaphis chuni lived to be 11,000 years old. Yes, a sponge is an animal—and it has a remarkable life-span.
Dogs come in a variety of breeds, some of which you may never have heard of before. While there are over 350 recognized dog breeds by International Canine Federation standards, extinct dogs have come and gone over the years. Sadly, quite a few dog breeds may no longer exist in the modern world.
The hippopotamus is considered to be one of the most dangerous animals in the world. They actually kill more humans yearly than lions, leopards, buffaloes, elephants, and rhinos combined. This makes it obvious to see why we never managed to domesticate them.
Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life.
Frogs & Salamanders: These seemingly delicate amphibians survived the extinction that wiped out larger animals. Lizards: These reptiles, distant relatives of dinosaurs, survived the extinction. Mammals: After the extinction, mammals came to dominate the land.
In fact, birds are commonly thought to be the only animals around today that are direct descendants of dinosaurs. So next time you visit a farm, take a moment to think about it. All those squawking chickens are actually the closest living relatives of the most incredible predator the world has ever known!
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
Large mammals, such as primates, cattle, horses, some antelopes, giraffes, hippopotamuses, rhinoceroses, elephants, seals, whales, dolphins, and porpoises, generally are pregnant with one offspring at a time, although they may have twin or multiple births on occasion.
WASHINGTON — The dodo bird isn't coming back anytime soon. Nor is the woolly mammoth. But a company working on technologies to bring back extinct species has attracted more investors, while other scientists are skeptical such feats are possible or a good idea.
Unfortunately, DNA slowly degrades, and once it's gone completely, there's no way to recover it. Researchers believe DNA has a half-life of 521 years, so after 6.8 million years, it's believed to be completely gone. That's why species like dinosaurs have virtually no chance of de-extinction.
Megalodons succumbed to global cooling due to the shrinking of their habitat, the vanishing of their favorite prey, and competition from other predators 3.5 million years ago.
