Quintuplet tiger cubs shown to public at South Korean zoo

A female endangered Korean (Siberian) tiger has given natural birth to five cubs. 

The theme park Everland, run by Samsung C&T Corp., on Aug. 12 said the five cubs were born on June 27 and have since been growing normally at Zootopia within the park in Yongin, Gyeonggi-do Province. The Korean tiger is a Class 1 endangered species protected by the government.

With just around 1,000 remaining in the world, the Korean tiger is included in the Convention on International Trade in Endangered Species of Wild Fauna and Flora Appendix 1.
The parents of the three female and two male cubs are mother Geon-gon and father Tae-ho, both of which were born in 2016. Two older siblings -- brother Tae-beom and sister Mu-gung – were born in February last year. Each of the five weighed only 1 kg after birth but quickly reached 5-6 kg 40 days after birth.

Korean tigers normally give birth to two or three cubs at one time, so five is considered highly unusual.

Zookeeper Kim Su-won said, "Their mother Geon-gon separately breast feeds the five new cubs, which often lose their chance to get milk due to their older siblings Tae-beom and Mu-gung's experience in nursing."
Everland is mulling whether to show from early October the new cubs to the public 100 days after their birth, and plan to unveil how they grow through social media.

Everland now has ten Korean tigers (five males and five females) at Zootopia apart from the five new cubs.
