Introduction of tiger:
Tiger brain capacity
According to Xinhua News Agency, London, the tiger and the lion are the kings of the beast, but who are more "mind"? A new study in the UK shows that tigers have a larger brain than lions and should be more "smart and courageous."
Researchers at the University of Oxford in the United Kingdom have reported that they have tested a large number of skull samples of tigers, lions, African leopards and jaguars. It was found that although the maximum length of the lion skull is greater than that of the tiger, its brain capacity is smaller than that of the tiger. Even the small female Balinese tiger (which once inhabited in Bali, Indonesia, was extinct in the last century) has a brain capacity that exceeds that of a large African male. lion. In addition, from the proportion of brain capacity in the entire cranial cavity, lions, African leopards and jaguars are almost the same, and the proportion of tigers is about 16% higher than them.
The press release issued by Oxford University said that lions are social animals, and tigers usually act alone. There have been theories that social interactions brought about by social groups contribute to brain development, but it seems to be open to question. Since these large felines originate from the same ancestor, further research will help to understand the causes that make their brains evolve differently.
According to Venezuelan Southern Television reported on April 10, 2016, the Wildlife Conservation Organization announced on the 10th that since 1900, the number of wild tigers in the world has risen for the first time.
According to reports, recently, the World Wildlife Fund (WWF) and the Global Tiger Forum statistics show that the number of wild tigers in the world has far exceeded the 3,200 in 2010, rising to 3,890. Ginette Hemley, senior vice president of the Wildlife Conservation Division of the World Wildlife Fund, said: "Trends are more important than data. The general direction of the current trend is correct." However, environmentalists warn that the increase in value is not It will definitely mean an increase in the number of wild tigers. They think that the improvement of the survey method is likely to be the reason for the increase in the number. It is reported that the number of tigers has been declining due to habitat loss and poaching problems.
