Amazon Flooded Forest - Giant Otter sign

Sign introducing the otter pair - male Tacutu from Hamburg Zoo and female Chelsea from Duisburg Zoo. Both are 3 years old.

do they have extra signage in Chinese or Malay, or only in English?

The main signage for each species (those large rectangular signs with the animals' picture and brief description, mounted on the ground - you can see them in the various exhibit photos) comes in multiple languages (English, Chinese and Malay). But the additional 'trivia' signs that come in different shapes and sizes are all in English.

ok, I found one which have the same birthday as me^^

I understand from park staff that the firstborn otter pup did not survive due to the female's inexperience. The pair have mated again already so hopefully there will be better news with the next litter.
