Although the zoo at Johore Hahru is not big, I found many kind of interesting animals and another creatures there. Lions, tigers and other animals moving about lazily in their cages. Some the animals appeared to be bored, and they took little interest in the visitors. The monkeys, however, showed its natural agility. Whenever they saw visitor, they ran towards him and begged something to eat. I was amused at their behavior. Most of them caught in Malaysia and their variety was amazing.
