Tigers - Panthera Tigris


The tiger had nine subspecies.  Three of these are extinct and the other six are on the critically endangered or endangered list according the IUCN (Union for the Conservation of Nature) Red List.  Tigers are the world’s largest cat.

 

1.       The Sumatran Tiger – Panthera Tigris Sumatrae


The name of the tiger is due to the fact that these tigers can only be found on the Indonesian island of Sumatra.  According the U.S. Fish and Wildlife Services, there are between 500 to 400 tigers left.  The Sumatran is the smallest of the remanding subspecies of tigers.  This tiger is on the critical endangered list.  The tiger has the darkest coat, and the black stipes are broad and closely spaced and even doubled.  It also has striped forelegs.  Most of the remaining tigers now live in five national parks, two game reserves and about 100 live in unprotected areas that most likely will be lost to agriculture in the future.  This is the greatest threat to these tigers, followed by poaching.  It is illegal to hunt the tiger but this does not stop them.  China is a large consumer of tiger parts, as well as Taiwan and South Korea and even in some North American cities.

Most of the remaining Sumatran tigers now live in five National Parks, two Game Reserves, though around 100 live in an unprotected area that will most likely be lost to agriculture in the near future.

2.      The Bengal Tiger – Panthera Tigris Tigris


This tiger is found in India and Bangladesh and also in Nepal, Bhutan and Burma.  They are also called the Royal Bengal Tiger.  They are the most common subspecies of the tiger and are the second largest of the remanding subspecies of tigers.  There orange coat can black or brown stripes.  Each cat has their own unique striping patterns.

Bengal tigers hunt medium and large sized animals, wild boar, badges and water buffaloes.  Their prey can also be small elephants and rhino calves.  The tiger can drag prey 5 times their own body weight.  The tiger hunts mostly at night, and they kill their prey by severing the spinal cord or by inflicting a suffocation bite, which is generally done on larger prey.  Habit loss and poaching are threats to the survival of this tiger.  They are not only killed for their skin but for their body parts which is used to make traditional Asian medicines.

White Bengal Tiger has a striking white coat.  This is caused by a double recessive allele in its genetic makeup and this only occurs once in every 10,000 births.

3.      The Indochinese Tiger – Panthera Tigris Corbetti


            This tiger is found in Cambodia, Laos, Burma and Thailand.  They are also called
            the Corbett’sTiger.  They have the darker shade of orange than any other subspecies of
            tigers.  The stripes act to help camouflage the tigers from their prey.  There are an estimated
            number of 1500 of these tigers left in the wild but because the tiger has a wide range some
            scientist believe that there could be only as few as 1200 left in the wild.  The tiger diet consist
            most of wild pig, wild cattle and wild deer.  The male tiger is about 8 to 9.5 feet long (2.43 to
            2.89 meters) and females are 7 to 8.5 feet long (2.13 to 2.5 meters).  The male weigh from
            330 to about 430 pounds (149 to 195 kilograms).  Habit close is also a bit concern, plus
            poaching.  Use of body parts in traditional medicines also put this tiger at risk.

4.        The Malayan Tiger – Panthera Tigris Jacksoni


               This tiger is a separate subspecies of the Indochinese tiger.  The Malayan tiger is very
               similar to the Indochinese tiger but it is smaller in size.  They are found exclusively the in the

               Subtropical forest in the southern tip of Thailand, and the peninsular Malaysia in
               South East Asia.

5        The Siberian Tiger – Panthera Tigris Altaica


They are the largest of the subspecies of tiger.  They are also called amur tiger.  There are about 350 to 450 in the wild.  They are     found in the Primosky and Khabarovski Krais areas of the Russian Far East, with a smaller population of about 35 individuals are found in the areas of the Russian Far East.

The tiger does not have strips on its forelegs like the sumatran tiger.  The tiger can weigh up to 660 pounds (300 kilograms).  The males can grow up to more than 10.5 feet (3.3 meters) from head to tail.  The same threats exist for these tigers, habit loss, poaching and body parts used for medicinal purpose.

The cross between the Bengal and Siberian tiger has a paler orange fur than other tiger subspecies.  They have brown stipes instead of black stripes.  The fur is much thicker than that of any other tigers living in southern Asia to help them with the cold winters.

6.      South China Tiger – Panthera Tigris Amoyensis


             These tigers are found in central and eastern China.  In 1970’s these tigers were
             considered as pest by the Chinese government and hunted to the brink of extinction.  They
             are on the critical endangered list and are nearly extinct.  There are about 47 tigers living in
             18 zoos in China.  There are no tigers left in the wild.  The tiger has a yellowish fur with 
             narrower and longer stripes than those of the Bengal tiger.  The male is bigger than the  
             female and is between 7.58 to 8.666 feet (2.310 to 2.64 meters) long.  The female is 7.25
             to 7.83 feet (2.21 to 2.38 meters) long.  The male weighs 287 to 386 pounds (130 to
             175 kilograms).  The female weighs 243 to 254 pounds (110 to 115 kilograms).  The tiger
             was known to attack man and cattle for invading its natural habitat.  The tiger could
             consume between 39 to 88 pounds in a single setting (18 to 40 kilograms).   The male
             tiger does not  mix with the female tigers, only when it is in the breeding season.  The tiger
             reaches maturity between 3 to 6 years.  The gestation period is 103 days.  The female tiger
             can deliver up to 7 cubs but the usual is 2 or 3 only.  The mother breast feed their cubs for 8 
             months and at the age of 2 months they start eating solid food and leave the den.   
             Between the age of 18 and 36 months, they are ready to hunt and become independent.

The future for these tigers does not look promising and it looks like they will be the next tiger to become extinct. Attempts are being made with breeding programs and so far they have been successful but a lot of work still needs to be done.

Extinct Tigers


 

1.        The Bali Tiger – Panthera Tigris Balica.


               This tiger used to be found only on the Bali Island in Indonesia.  It was the smallest tiger of 
               the tiger subspecies. The females could weigh as little as 14 pounds (75 kilograms) and
               the males could reach around 200 to 220 pounds (90 to 100 kilograms).  The Bali tiger
               reached extinction through hunting.  Bali tigers had darker, shorter fur than any other t
               tiger subspecies.  The tiger had a bar-shaped pattern on its head.  They had a lifespan
               roughly of 8 to 10 years in the wild.

2.        The Caspian Tiger – Panthera Tigris Virgata.


               This tiger was caller the Hyrcanian Tiger, Persian Tiger and even the Turan Tiger.  These
               tigers was lived around the Caspian Sea, through Turkey, Iran and Central Asia to the
               the Chinese desert of Xinjiang.  They were some of the biggest of the tiger subspecies, 
               together with the Bengal tiger.  Males usually exceeded 6.56 feet (2 meters) in length. 
               The tiger had a brighter golden coat, with brown-gold stripes.  In winter the coat would
               become less bright and the pattern would not be so pronounced.  The stripes were  
               narrower and closer together than any of the other tiger subspecies.  When the Russians 
               came to Turkey in the late 1800s, they hunted the Caspian Tiger.   They also hunted the 
               natural prey of the tiger so many of the tigers would die from starvation.  In the 1990s it 
               was believed the last of these tigers died, but nobody seemed to have interest in those
               days, so it was never investigated or confirmed.

3        The Java Tiger – Panthera Tigris Sondaica


These tigers were found exclusively on the island of Java.  The male tigers were very small, about 250 pounds (115 kilograms) and the females were even smaller.  Their noses were         long and narrow.  Their stripes were also narrow.

 In 1947 these tigers were protected but it came too late.  It was in the 1970s that this tiger came extinct.  It was believed that the tigers were poisoned by the locals who wanted to protect themselves, and of cause hunted for financial gains.  They also faced starvation and their prey was being killed to the point of extinction.
