Crocodile & Giant Tortoise At Ostrich Farm

...on the day tour to one Ostrich Farm in Cape town, actually it is this crocodile caught my eyes. Its big mouth was opening still for more than 20 minutes, and its skin color is very nice... 

...and this giant tortoise caught my attention too. How to determine the exact age of a turtle? We were told that the rings in the shell of the tortoise could be used for assessing the age of the tortoise, is it true?
Anyway this is the first tortoise we saw in South Africa, and it is a giant tortoise. I saw a few different type of tortoise in the next few days...
