Why Ligers Are Bigger Than Tigons

Ligers and tigons are two of the most impressive and most ferocious cat species in the world. Even though they are crossbred, these felines are impressive and stand out due to their amazing sizes. In fact, the liger is the biggest living cat in the world, simply dwarfing both tigers and lions in size and weight. However, why are ligers to much bigger than tigons?


Source

Well, the large size of a liger and small size of a tigon are due to a genetic phenomenon called “genomic imprinting”, meaning the unequal expression of genes depending on parent of origin, that is whether certain growth genes are inherited from the male or the female. In simpler words, lions and tigers – in fact, all big felines – have imprinted genes which can be expressed maternally or paternally, with great restrictions to species and gender. This is also linked to the species’ lifestyle and breeding strategy – whether the female mates with only one male while in heat (non-competitive) or with more than one male (competitive). This results in “growth dysplasia”.

Lions live in prides led by several adult males. The lionesses mate with each of those males. Each male desires his offspring to be the ones to survive. However, the female’s genes want multiple offspring to survive. The lion’s genes promote the size of the offspring to make sure that his offspring out-compete any other offspring in the womb at the same time. Genes from the lioness inhibit growth to make sure that as many offspring as possible survive and that all the cubs have an equal chance.

By contrast, tigers are largely solitary and a female on heat normally only mates with a single male. There is no competition for space in the womb, so the male tiger’s genes do not need to promote larger offspring. Therefore, there is no need for the tigress to compensate, so the offspring’s growth goes uninhibited.


Liger

When a male lion mates with a female tigress, though, his genes promote large offspring growth because lions are adapted to a competitive breeding strategy. On the other hand, the tigress does not inhibit the growth because she is adapted to a non-competitive strategy. Therefore, the offspring of a male lion and female tigress – the liger – grows larger and stronger than either parent because the effects do not cancel each other out. While it is true that it takes several years for ligers to reach full adult size, the fact that ligers never stop growing is a complete and utter myth.

When a male tiger mates with a female lioness, his genes do not promote large offspring growth because tigers are adapted to a non-competitive breeding strategy. On the other hand, the lioness inhibits the growth because she is adapted to a competitive strategy. Due to this uneven match, the offspring of a male tiger and female lioness – the tigon – is often smaller and less robust than either parent.

Growth dysplasia has other effects, as well. It can affect the size of the placenta, causing miscarriage, or it can cause the embryo to be aborted at an early stage due to abnormal growth. Also, the cub may be stillborn or may only survive a few days after birth.


Tigon

This is the scientific explanation why ligers are much bigger than tigons. Other hypothesis are also taken into consideration, but this is the most plausible one. Remember that this explanation is greatly simplified, as a number of other genes are contributed unequally by the male and female parents and also affect the general health and longevity of the offspring.

Ligers Health Problems

Filed under: Facts - 18 Oct 2012  | Share on :

Ligers, such as many other hybrid animals, are cute, intelligent and quite unique. In the world, there are numerous hybrids between different species. Most commonly, hybrids can be found in captivity, but it is important to know that hybridization occurs into the wild, as well.

Hybridization can occur involuntarily, actually in some cases being very difficult to distinguish different species from each other. Ligers are hybrids born in captivity, to a lion father and a tigress mother. As lion and tiger populations do not live in the same environment into the wild, they can only breed in captivity.


Source

So, the liger is a cross breed between a female tiger and a male lion. The first liger in history was born in 1824, in Asia. Only in 1935 another liger was born in South Africa. Nowadays, the best known liger in the world is Hercules. Hercules can be visited at Jungle Island, in Florida. This beautiful liger has actually become very famous. He was featured in many television shows, including Good Morning America, The Today Show and 60 minutes. Hercules is the largest cat in the world, weighting nine hundred pounds. He is healthy and beautiful, Hercules having no health problems.

This is actually considered to be a lucky situation, as ligers can be born with birth defects. Most do not survive the first year of life. Some liger cubs die within the first week.


Source

Some specialists claim that birth defects may be caused by the fact that the baby liger is too big to be carried by a tigress. For most female tigers, carrying the big cub can turn out to be extremely difficult.

Actually, there are many speculations on the fact that ligers develop health problems. They are believed to be more vulnerable to a series of diseases than any other big cats and their entire life is linked to various health issues.


Source

Here are some problems associated with ligers:

  • The tigress mom most commonly needs a C-Section due to the large size of her baby. Giving birth can be fatal for the tigress.
  • Many ligers do not survive more than a few days or weeks after birth.
  • Ligers have unstable temperaments, which cannot be predicted.
  • Ligers are known to have numerous health problems, caused by genetic abnormalities and neurological defects.
  • Ligers are more likely to develop conditions such as cancer and arthritis.
  • They have a lifespan shorter than the one of either of their parents.


Source

While some claim that the entire life of a liger is associated with difficulties, others consider that such hypotheses are wrong.

  • For instance, even though mortality rates of liger cubs are high, so are the rates of tiger cubs. 
  • A tigress was able to give birth to 12 ligers in China, while only one of the cubs died. This means that tigresses are able to carry pregnancies with no risks. 
  • A study has shown that ligers are much healthier than lions. Ligers can live more than lions and tigers, the best example being a female liger who lived no less than 24 years in captivity.
  • The speculation that ligers have a weaker heart is just a myth. In fact, there are no health issues that can only be associated to ligers. It is impossible to say that ligers tend to live shorter than lions or tigers due to their severe health problems. And the best example is Hercules.

The topic on ligers health problems remains a controversial one, so opinions are shared. Despite the health issues that ligers may or may not be suffering from, this is an amazing species. Ligers are the biggest and most impressive cats in the world.

Ligers Get the Best of Both Parents

Filed under: Facts - 17 Jul 2012  | Share on :

[Facebook] [Twitter]

While there is only a handful of ligers in the world, the people’s interest for them is becoming higher by the day. This fascinating hybrid species is both intriguing and fascinating, since ligers have some pretty unique features and characteristics. They are a hybrid cross between male lions and tigresses and are now the largest felines ever known. With such amazing species as parents, the result of their crossbreed could not be less phenomenal.


Source

The most interesting thing about ligers is that they have inherited the best of both parents. They resemble both the lions and the tigers, but they only got the good parts from these species.


Source

1. Ligers enjoy swimming, just like tigers. Lions are not fond of the water and can barely swim.

2. Ligers are very sociable, just like lions. Tigers do not socialize and tend to be more solitary. However, as there are not many ligers in the world, they live a solitary life in captivity, usually in zoos or sanctuaries. They are always surrounded by people (either caregivers or zoo visitors), so they are not utterly alone.

3. Ligers have an amazing speed, of about 50 mph (80 km/h) and even 60 mph in some cases. This capability of speeding themselves comes from their mothers. Lions are also fast, but not as fast as tigers. Therefore, they have become the second-fastest feline runners in the world, topped only by the cheetah. This may be hard to believe, considering their impressive size and large bodies. However, it is their large bodies and heavy weight that helps them reach such a speed.

 

4. Ligers can grab the prey down, precisely because of their speed and strength. They can also hunt big preys, which is a characteristic of both lions and tigers.

5. Ligers can be ambush hunters, just like their parents. This means that they use their natural cover to stalk their victims up close until making the move and attacking.

6. Ligers tend to inherit the lions’ physical appearance. They look like giant lions with muted stripes or spots running through it. The spots come from the lion and the stripes come from the tigress.

7. Ligers roar like lions and chuff like tigers. The grunt at the end is clearly a lion “trademark”. It is very interesting how they make both lion and tiger sounds.


Source

Even though they have inherited so many great features from their parents, ligers grow much larger than either parent. In average, they can reach over 1000 pounds (450 kilos) in weight and more than 12 ft (6.7 meters) in length, which makes them about 40% larger than their parents. This is normal for all crossbreeds, since hybridization often leads to gigantism.

Clearly, ligers get the best of both parents. They are quite lucky, since this is rarely the case with hybrid species. They also look amazing and have an impressive figure, which makes them extremely appealing for numerous people. After all, not everyday they get the chance to see such freaks of nature. Or, better said, freaks of scientists who one day thought: “how about we make a hybrid?”. Luckily, their experiment did not result in a horrible mutation, but in a beautiful animal which is a real treat for the eye.

Point Facts On The Amazing Ligers

Filed under: Facts - 03 Jul 2012  | Share on :

We all know that ligers are amazing animals and that they are the result of the cross breeding between a lion and a tiger. There are many more other interesting facts about these felines that are known to smaller groups of people. Many have focused on learning where they can actually see these animals in zoos and in natural preserves, while others have considered the fact that their apparition is a matter of controversy, due to the fact that the breeding may not have been accidental. Regardless, before forming an opinion it is best to have all the facts in mind and to know why you have opted for a certain side of the story.

The first breeding was not accidental at all. It was actually orchestrated by Mr. Thomas Atkins. Due to his arrangement of the lions and of the tigers, the breeding was bound to happen. It started in 1824, with the first litter born in Windsor, which was formed out of one female and two males. The second litter came the following year at Clapham Common. In 1827, the third litter surfaced in Edinburgh, followed by the forth one the next year in Windsor. The fifth and the sixth litters came in 1831 at Kensington and in 1833 at the Zoological Garden of Liverpool. Although the species was developed so many years ago, many people have taken notice of these animals in the film Napoleon Dynamite.

Another interesting fact about the species of felines is that it is the largest one in the world, weighting around 900 lbs, but with a maximum reached point of 1600 lbs and 12 feet in height. The major mass of these animals is created by the fact that they have strong lion genes, but also by the fact that they require a 100 pounds of meat meal for each sitting. Although they are very massive, they can run at an average speed of up to 50 miles per hour. From the category of lion and tiger combinations, which have created ligers, you should also know that these have inherited both “speech” forms from their parents, meaning that they can roar, but they can also puff. Among some of the preferences of these animals, you can count swimming and… chocolate! There are many more interesting facts about the ligers, which will surely make you want to see them in zoos.
