What are the endangered animals in Eravikulam National Park?

 

There is a rise in the Nilgiri tahr numbers in Eravikulam National Park. The annual census held in April sighted 803 tahrs inside the park compared to 785 last year

The Nilgiri tahr is an endangered mountain goat found only in the hill ranges of the Western Ghats in Kerala and Tamil Nadu.

People visiting the Eravikulam National Park (ENP) near Munnar are often amazed to see Nilgiri tahrs grazing nonchalantly in the tourism zone. Most of the park is out of bounds for visitors except for this demarcated area. Here the tahrs are almost tame, even allowing tourists to come close and click pictures!

In stark contrast, the tahrs in the core area of the park, where only park staff and researchers are allowed to go, are extremely shy, fleeing at the sight and sound of humans.

It is said that the tahr in the tourism zone became accustomed to people because of Walter Mackay, the manager of the Rajamalai tea estate in the 1950s. The estate was situated inside the present sanctuary (it was declared a wildlife sanctuary in 1975 and a national park in 1978). Mackay would toot his cars horn while driving through the sanctuary, attracting herds of tahrs. They would mob his car to be rewarded with handfuls of biscuits!

Of course, visitors today are forbidden to feed and pet the tahrs.

The tahr feeds on a variety of herbs, shrubs and grass. Sure-footed and agile like others of its kind, it can negotiate sheer cliffs with amazing ease.

The Nilgiri tahr is endemic to the open grasslands in the upper reaches of the Western Ghats. It is found mainly in the Nilgiri the Anaimalai and Nelliyampathy hill ranges. A mature male tahr has a coat of deep brown and is called a saddleback for the broad swathe of lighter-coloured fur down its back. The females are smaller and lighter in colour. Both have horns that curve straight back.

In the Eravikulam National Park (ENP), the leopard is its only known predator.

The females and juveniles stay close together in a herd. sometimes numbering over a hundred. The males are usually loners and join the herd during breeding time. The females calve from January to February. The park is closed to tourists at this time

There are around 800 tahrs in the ENP and small numbers in the Parambikulam Tiger Reserve and Silent Valley National Park in Kerala. The tahr is also found in Tamil Nadu’s Anaimalai hills. Around 60% of tahr habitat in the Western Ghats could be lost to climate change from the 2030s onwards. There are only around 3,120 tahrs left in the wild.

In the early 1950s, poachers hunted the tahrs (their meat was a much sought-after delicacy) to the point of extinction. The tea company that then owned the area stepped in and declared it a sanctuary. A check post was set up at the site of the present Forest Department outpost, and all vehicles passing through the area were searched for firearms, snares and tahr carcasses. This went a long way in stamping out poaching.

Munnars High Range Wildlife and Environment Preservation Association is an NGO set up in 1928 by conservation-minded British tea planters.

Even today, tea and coffee planters in south India are actively involved in conservation and the Nilgiri tahr is a symbol of their success.

What is the name of the smallest bear in the world?

The sun bear is the smallest bear species in the world. It gets its name from the yellow or creamy white mark on its chest that resembles the rising sun. It is also known as the Malayan bear.

Compared to the biggest bear species – the polar bear and the Kodiak or grizzly bear, which stand almost 3 metres (9.8 feet) tall and weigh around 635 kilos, the sun bear grows to about 1.2 metres (36 cm) in length and weighs around 40 kilos. It has a black coat and a light grey or orange nose. The feet are tipped with long sickle-shaped claws, which are sharper and curvier than in most other bear species. The soles are hairless.

Sun bears build nests in trees by breaking or bending the branches. They spend the day in the nests, sleeping and basking. They hunt only at night.

In 1978, the IUCN included the sun bear in its Red List of endangered species. Although its population has decreased due to hunting, a few thousand can still be found in the forests of the Malay Peninsula, Java, Sumatra, Myanmar, Borneo and Thailand.

Why are stonefish so poisonous?

Stonefish is perhaps one of the world’s best camouflaged fish. But it is also the most venomous. Found in shallow waters of the tropical Indo-Pacific, stonefish stay in the muddy or rocky bottoms of marine environments, living among rocks or coral. It may look like a stone on the ocean floor and deceptively stays blended with the ocean floor while hunting. The skin covered by wart-like lumps helps it in camouflage. It has venomous spines and when stepped on accidentally or there is a contact, it can sting. The sting is painful and can be fatal. Did you know that the fish is a delicacy in certain parts of Asia after its venomous spines are removed.

What is a venomous lizard native to parts of the US and Mexico?

Native to the USA and Mexico, the Gila monster is a small, venomous lizard that is known to spend more than 90% of its life below the ground. As such you may not encounter the Gila monsters in the wild but bites are known to occur at times. The venomous lizard is known to use its venom only for defensive purposes. A mild neurotoxin, the venom of the creature is produced in the lizards’ salivary glands. The saliva is toxic and is found to contain the hormone exendin-4 which could be used to treat type 2 diabetes. Although its venom is deadly, it also has potential medicinal use. While the lizard is strictly nocturnal, above-ground sightings of it are also seen during the day.

Why is the box jellyfish so dangerous?

 

BOX JELLYFISH

The box jellyfish can perhaps be regarded as one of the most dangerous animals in the sea because of the deadly venom produced by some species. They dwell in the warm coastal marine waters. The deadliest species is the Chironex fleckeri or the Australian box jellyfish. It is also the largest species among the box jellyfish. The venom is considered deadly because of the toxins that can attack the nervous system, skin and heart. Death is known to occur quickly. Also called sea wasps and marine stingers, the box jellyfish are pale blue and transparent in colour. One look at the marine creature and you will know why it received the unique name. The distinct cube-like shape of their bell is how the name came about. Another interesting fact about box jellyfish is that they are highly advanced when compared to other jellyfish rather than drifting. They have developed the ability to move.

Is the inland or western taipan oxyuranus microlepidotus?

Native to central Australia, the Inland Taipan snake usually lives in desert areas. Also called a fierce snake, the Inland Taipan is the world’s most venomous snake. The venom of the snake is very potent with experts noting that a drop of the snake’s venom is enough to kill 100 people. The snake is quite shy and encounters with humans are rare. The venom is so powerful that it could kill the victim within hours if medical treatment is not given.
