It will be a mathematically challenging start to the year for zoo keepers at two of the region's biggest attractions.
They have the daunting task of counting the almost 4,000 species in their care at Banham Zoo, near Diss, and Africa Alive! at Kessingland.
Some of the animals are easier to count than others.
Cheetahs are quite easy to spot but spare a thought for the poor keeper who has the slightly trickier job of counting about 1,000 Madagascar hissing cockroaches at Banham Zoo.
This will involve taking them out of their tank and then painstakingly counting them back in - one at a time.
The information is collated through a database which is used by zoos around the world so the information about different animals can be shared for conservation purposes.
Some of the new arrivals this year include a rare Grevy's zebra born at Banham Zoo and a black lemur and two black and white ruffed lemurs at Africa Alive!
