Ligers and Weaker Heart
There are many speculations which speculate that ligers have a weaker heart. This is another wrong fallacy and false notion against the ligers. Ligers do not have any such issues pertaining to a weaker heart. A heart of a liger is as normal as that of the lion and tiger and there has been never sign or symptom which indicate that ligers have a weaker heart. Moreover, in our study, about the ligers where different deaths of the ligers were analyzed, none of the ligers have died because of the weaker heart. Therefore, it is absolutely wrong to conclude about ligers that they have a very weak heart.
Ligers do live a very active life. They run very fast. They are lightening fast. They have same hunting instincts like that of the lions and tigers. Moreover; they love to swim within water as well. All of these examples deny heart problem or weaker heart within ligers.
If ligers have a weaker heart, they should not be running that much faster, they should be very slow, lazy and prefer to sit. Unlike these notions, ligers have a running speed of 60 miles per hour. This is a very fast speed for a big cat and is only fastest after Cheetah's top speed of 70 miles per hour. Any living animal who will have a heart problem may not run that fast or die after running that much faster.
Let's compare the heart size of the liger with that of the other big cats. Of course ligers do have a bigger heart than lions tigers and jaguars etc. but that bigger heart is there to support the huge body and the blood circulation requirements of the liger.
For any living organism it will be impossible to grow that much bigger and huge (like Liger), if it has a weaker heart. Usually organisms with such diseases die early and tend to remain very lazy. Ligers on the other hand are very curious and active.
According to some other studies, a weaker heart is responsible for the swelling of the legs. This can become highly painful for the individuals to walk around. A species with a weaker heart can not breath properly and it can even abandons its food. However, when we look at the ligers, their respiration is normal, their food intake is normal and massive which is about 3 times more than lions and tigers. So we can safely conclude from here that weaker heart is just the matter of speculation and stupid assumption within ligers. These speculations have been fabricated and formulated by anti-liger activists who mostly use lies against ligers.
