Why is the brown spider monkey considered as an endangered animal?

            The brown spider monkey is one of the seven species of spider monkeys that can be spotted in the forests of Northern Colombia and Northwestern Venezuela.

            They are primates that prefer undisturbed dense forests, and stay most of the time high in trees. Instead of walking or running on all fours, these monkeys travel mostly by swinging and climbing.

            However, it is not for their strange eating habits that the brown spider monkeys are in the news, but for the threat of extinction they face. This species was among the world’s 25 most endangered primates as of 2004 and 2006, and has been classified as critically endangered, by the IUCN Red List.

            Hunting and habitat destruction due to human encroachment, conversion of forests into agricultural lands etc. are the main factors that threaten them. Its slow reproductive rate also makes the situation worse.

            Serrania de San Lucas in southern Bolivar is one of the places where the monkeys are protected. There are also various zoos, especially in Europe, that provide them safe shelters.

What are the threats to Siamese crocodiles?

            The name Siamese crocodiles may not be familiar to most of us. They are among the most endangered reptiles in the world today. These fresh water crocodiles were previously found throughout South Asia, in Thailand, Laos, Cambodia, Vietnam, and Malaysia. But today, their surviving population can be seen only in the Mekong River basin and wetlands in Cambodia, and a few other places. Even here, their habitat is fragmented, owing to hunting and human activities.

            The main threats to Siamese crocodiles are humans. Aggressive hunting for crocodile skin, conversion of rainforest habitats into agricultural farms, use of pesticides and chemical fertilisers etc have contributed greatly to the declining population of these reptiles. It is said that there are not more than 5000 Siamese crocodiles alive today.

            However, the crocodiles are extensively bred and maintained in captivity, in Cambodia, as well as in Thailand. There are also many conservation programmes underway in these two countries, which gives a little hope regarding the future of these endangered crocodiles.

Why is the Malayan tiger an endangered animal?

            The Malayan tiger is a subspecies of tiger found in the southern and central parts of the Malay Peninsula, and in the southern tip of Thailand. Unlike other tigers, they mostly live in open woodlands. Deer, wild boar, gaur, tapir, sun bear, and elephant calves are the main food source of these wild animals.

            In 2015, the Malayan tigers were classified as critically endangered by the IUCN. This was because their population was estimated to be less than 250, and had declined by more than 25 per cent in seven years.

            The main reasons for the fall in the Malayan tiger population are hunting and habitat destruction. The tigers especially are of high demand across markets in Asia, for their bush meat and bones, which are also used as a sign of wealth, or for making folk medicine.

            The Malaysian Conservation Alliance for Tigers (MYCAT), comprising the Malaysian Nature Society (MNS), Traffic South-east Asia, Wildlife Conservation Society, and WWF-Malaysia is a prominent organisation that works towards conserving this subspecies.

Why is the African wild ass rare?

            By scientific classification, the African wild ass is a member of the horse family. But it can be best defined as an ancestor of domestic donkeys. These are animals that live in the deserts, and other arid areas of Africa, mainly Ethiopia, Eritrea and Somalia.

            The most important characteristic of this wild animal is that it can survive water loss of up to 30 per cent of its body weight, and drink enough water to replace it in under 5 minutes! Typically, these animals have stocky bodies with smooth coats in light grey to fawn colours. Wild asses can eat hard and dry plants too. However, in spite of thou ability to survive tough conditions, these animals are reducing in their number. They have been classified as critically endangered. The main reasons for this situation are inter-breeding, poaching, hunting and competition for food.

            Another reason is poaching for food and traditional medicine, which is quite common in African countries. Then, there is the competition with domestic livestock for grazing, as well as water. This is caused by agricultural development, which poses further threats to the survival of these wild asses.

Why is the addax an important animal?

            The addax is a critically endangered desert antelope found in the Sahara Desert in Africa. It is also known as a white antelope.

            This animal has many interesting features and one of them is the ability to change colour of its coat, depending on the season. It could be grey or brown in winter, and sandy or white in summer. The neck and head of these animals is mainly brown.

            The addax is a desert animal that can live in a very harsh climate where no other animals can survive. This also means they have no particular competition for food or water. Under such circumstances how could their population drop to levels as low as to become ‘critically’ endangered? Well, the only answer to this would be human activities.

            The biggest threat these animals face is from people who visit their ranges in vehicles. They kill these slow-moving antelopes. It is said that when a car follows a herd of addax, they desperately try to escape, and later run out of energy, only to get killed.

Why is the radiated tortoise an endangered animal?

               A radiated tortoise is one of the most attractive species in the family, native to Southern Madagascar. Typically, these groups of tortoises have bright yellow skin coloration with black markings on the head. They also have high-domed black to brown shells, covered with yellow or orange star like patterns. This is what particularly makes the animal stunning.

               Radiated tortoises generally lead solitary lives, but are sometimes found grazing together.

               To protect themselves from predators, the tortoises pull their soft limbs and head inside their hard shells. They also make loud screeching noises during times of crises.

               Another interesting characteristic is their lifespan. Radiated tortoises live for a very long time, sometimes up to the age of 188! However their lives are often cut short by merciless humans and their activities. As a result, this species have become critically endangered. The reasons for this are poaching and destruction of habitat. The commercial trade of these aquatic beings and their pet trade are illegal.
