The Chester Zoo's baby Sumatran orangutan, Tripa.

Now nearly 6 months old, this baby boy and his mom share a close bond.

Emma, a Sumatran orangutan, rarely lets baby Tripa out of her sight at the Chester Zoo in the U.K.

The little guy depends on mom for TLC — as well as for food and a way to get around. Young orangutans spend up to eight years with their moms.

“Emma is a fantastic mum and is doing a brilliant job, cradling her baby and not letting him out of her arms,” said the zoo’s curator of mammals, Tim Rowlands, just after the ape’s October birth.

Sumatran orangutans are critically endangered in the wild, where their population is estimated at less than 7,000.
