The bear's white coat, which helps it blend with its icy environs, is thick, and covers a thick fat layer. These two adaptations enable polar bears to survive harsh Arctic winters.

Western lowland gorillas (Gorilla gorilla gorilla) are critically endangered, with approximately 100,000 remaining in the wild. They live in the tropical forests of West Africa. Countries include Cameroon, Nigeria, Central African Republic, Angola, Gabon, Republic of Congo and Equatorial Guinea.
Gorillas are born after approximately 9 months of gestation (just like humans). Newborn babies weigh 3-5 pounds and cling to their mothers' hair immediately. Females usually give birth to a single offspring, although occasionally twins can be born. Mothers will hold their babies all the time for about the first four months of life. Infants start trying solid foods around 6 months of age but nurse until they are 3 or 4 years old.
