What animals are not kept in captivity? Every 50-100 million years, about 95% of all the living species extinct on our planet. Scientists refer to this process as Holocene Extinction. And today, there are a lot of animals that are on the brink of extinction. For example, one of the rarest mammals on the planet is the Javan Rhino. Less than 70 are left, and they all live in a National Park on the island of Java, Indonesia. Of the 5 total rhino species, they're the most endangered one. Scientists aren't sure how long they live but guess somewhere between 30 – 40 years.
But there are other reasons why some animals are not kept in zoos. Even if you absolutely love aquariums and have been to dozens of them, there's one sea creature you’ll never ever come across there. Not a single aquarium in the world has a great white shark. In the past, many have tried adding great whites along with other sharks in their tanks, but it never worked out. They’d stop eating and even struggle to swim. Doesn’t make for great business either: it’s too costly to keep the great shark because a large enough tank will need millions of gallons of water.
Wow, the appearance of this guy is not so attractive, but it is not fair competition internationally. Its natural habitat looks like other ordinary fish. It is a deep-sea resident. It lives on the coast of Australia. The spotted fish thrive about 3000 feet below the water surface. The pressure at these depths is higher than the pressure that I and I are used to in the past. 120 times that only a powerful submarine can go this drooping creature does not have bones or too much muscle deep, but has jellylike flesh to resist extreme underwater pressure.
Great white shark
You will never find great white sharks in any aquarium in the past. Many people have tried to add great white sharks in their tanks with other sharks, but they have never succeeded. They will stop eating and even struggle.
Swimming is not conducive to big business, because keeping a large enough tank requires large enough water, so the cost of keeping a good white is too high millions of gallons of water. These fish don’t like to stay in one place for a long time. They prefer open waters because they can swim long distances. We have never seen one in captivity since the 1970s.
The saola, commonly known as the "Asian unicorn", was discovered in 1992. It lives on the gleaming hillside between Laos and Vietnam. It looks like an antelope, but genetic tests show that it is more closely related to cows. Saola is one of the rarest large mammals. According to the world survey, there are only 70 to 750 left in the wild. Yes, the range is very large. Experts can't get a more accurate number as they can't be detected, only two were caught and examined.
The narwhals sea unicorns there are more than eighty thousand of these creatures but they are still near threatened they have long narrow fangs sticking out of their heads this unicorn like tusk is actually a tooth that can grow up to 10 feet they belong to the family of whales but unlike their relatives they do not migrate, narwhals spend their lives in the arctic waters of Greenland Canada Norway and Russia live up to 50 years in the wild but cannot survive in captivity, so if you want to see one in real life, the zoo is not the place to look.
Unlike the other creatures on the list, swallows are very common. Even though they are one of the most widespread species, they are not suitable for eating on airplanes in zoos. They may recognize this from the gorgeous blue feathers from head to tail. A beautiful bird. Literally, they then catch food in the air, which is why they only feed on flying insects, so they need to live in large aviaries and have enough flying space, and most zoos cannot provide such insects.
You will find many lowland gorillas raised in captivity, but they are different for mountain gorillas. These apes have longer hair and are darker than brown. There are only about 1,000 species in the wild, making them an endangered species. Mountain gorillas usually spend a quarter of their time eating in the 60s and 70s. There are many attempts to catch them and start captive populations, but because of the lack of health of gorillas, they cannot be in a closed environment under special dietary requirements. The other problem may be pressure. There are no mountain gorillas in any facility.
Jumping back into the water, I got a Giant squid, a behemoth that inspired the legend of the sea monster. This creature is still a mystery for scientists. Their deep and harsh marine environment makes it difficult for them to study. The only researcher was washed from rare specimens in 2004. Researchers in Japan caught it on the shore. The first batch of live squids, two years later, they managed to surface a squid, because they live in the deep ocean, their eyes are as big as a beach ball, they can see things until today, the darkest in the ocean In places, it’s still difficult for other creatures to see anything, and the giant squid has never been caught or imprisoned for comprehensive research.
Next, I got the rarest large mammals on the planet. There are less than 70 Javanese rhinos left. They all live in the national parks of five rhino species in Java, Indonesia, and they are one of the most endangered scientists. Determine the length of their lifespan, but guess that the area where they live is prone to tsunamis for about 30 to 40 years. If any of these volcanoes erupt and the rhinos may become extinct, they are also close to many active volcanoes.
The creature you may never have heard of is the Malagasy Indri (Indri), a unique primate that relies on trees to move around and feed them in the wild for 15 to 18 years, but Under captivity, they barely reared for a year, probably because they could not cope with stress and interference well. Experts believed that their diet was so special that they could not be raised in captivity. They also noticed taken away from the wild The animals will not reproduce.
Pink Fairy Armadillo
The pink fairy armadillo has no wings or magic, but it is still a cute little animal with a pink shell, like a living radiator. It is the smallest of all armadillos. It uses bulky front paws throughout its life. Dig a hole. The earth is mostly at night and it is difficult to find it, let alone being captured, which is why scientists can’t study this little guy very much, and you will only find it in central Argentina.
