If you are thinking about getting a pet, but don't want cat or dog, there are a few unusual animals at a pet and flower market in Hangzhou, Zhejiang province, that may interest you. From brightly colored frog to blowfish and sesarmid crab, those exotic pets can bring you more fun and joy.

But experts warn that people need to think twice before keeping one of those unusual pets. If people are interested in them, they need to learn more about them, and do not just throw them away if it's difficult to look after, as they might cause damage to local ecosystem.
