A young baboon screams in pain when a sibling does some nibbling that is just a bit too firm.
The playful animals appeared to be showing off for the crowds at Hagenbeck Zoo, near Hamburg.
Keepers make sure feeding time comes when the animal park is at its busiest, to make sure there is some entertainment.
Ouch: These youngsters get their teeth into yet another play session
The mischievous youngsters have been keeping the crowds amused with their naughty antics. Like any little ones the latest arrivals obviously find it hard to sit still - running rings around the adult baboons.
Their action packed days are filled with play fighting, hide and seek, climbing and running.
The only time that peace reigns in the enclosure is when it's snack time or when a cuddle from mom is required.
However, the manic monkeys don't stay still for long and are soon back to causing as much mayhem as possible.
The zoo's collection began in 1863 with animals that belonged to Carl Hagenbeck Sr, a fishmonger who became an amateur animal collector.
The park itself was founded by Carl Hagenbeck Jr in 1907. It is known for being the first zoo to use open enclosures surrounded by moats, rather than barred cages, to better approximate animals' natural environments.
In 1863 the elder Hagenbeck began collecting exotic animals that came through the port. By the 1870s, the trade had proved more lucrative than his fish shop, and Hagenbeck had become one of the most prominent exotic animal traders in all of Europe.
In the 1890s Hagenbeck created his first 'panorama' exhibit and patented the idea in 1896. The display was the 'Northern Panorama', the foreground featured seals and walruses in a pool.
Hidden to the zoos patrons was a moat behind the pool. Beyond the moat were reindeer, and beyond a second hidden moat were polar bears. By hiding the moats, the animals appeared to be together in one landscape.
In 1907, Hagenbeck constructed a new facility outside of Hamburg which he called Tierpark Hagenbeck (without the 'H' that was in Thierpark) which is still the location of the facility today.

Settling down: The youngsters get to grips with a light afternoon snack
Hagenbeck sought to design the entire zoo with his panorama system. He also sought to demonstrate that animals from warmer climates did not need to live in expensive, humid, foreboding buildings. Instead, Hagenbeck again sought to make his displays realistic.
Using data that he had compiled running his circus, Hagenbeck had estimates of how high and far different animals could leap.
Using this data, he built moats filled with water or an empty pit that he determined the animals could not cross. Using moats to separate animals that did not swim, one could look across an expanse of the zoo and see many animals at once, as if in the wild.
Previously, zoos had 'not' grouped animal by species, but Hagenbeck revolutionized the layout of zoos, grouping his animals by species. Hagenbeck's design was a popular success.
In 1913, he designed the first monkey-rock exhibit, in this case an artificial crag with a 16-ft moat. The rock was populated by around 200 Hamadryas baboons.
The Hamadryas Baboon is a baboon from the Old World monkey family. It is the northernmost of all the baboons; its range extends from the Red Sea in Egypt to Eritrea, Ethiopia and Somalia.
It also lives on the Arabian peninsula (Saudi Arabia and Yemen). It was a sacred animal to the ancient Egyptians as the attendant of Thoth, and so, is also called the Sacred Baboon.
