With her huge doe eyes and fluffy hair, it's hard to believe that this baby spider monkey was abandoned by her mother at birth.
Little Estela and her mother Sunshine failed to bond after she was born in January forcing primate keepers at Melbourne Zoo to step in and care for her around the clock to ensure her survival.
Primate supervisor Jess McKelson and her team have had to feed the tiny newborn a formula mixture by hand to build up her strength.
Hanging tough: The baby Spider Monkey which is native to Central America, is currently receiving six feeds of formula a day and is now slowly being introduced to solid foods
What a cutie! It seems hard to believe that this adorable baby spider monkey was abandoned by its mother, but at least grandmother Sonya is on hand at Melbourne Zoo to ensure little Estela is behaving herself
But the playful youngster is growing bigger by the day and is now being introduced to solid food.
Luckily, grandmother Sonya is on hand to keep a watchful eye on the mischievous toddler who thinks nothing of playfully teasing and prodding her surrogate family.
Spider monkeys are often found in the tropical forests of Central and South America, from southern Mexico to Brazil.
They have disproportionately long limbs and a long prehensile tail makes them one of the largest New World monkeys and gives rise to their common name.

They primarily eat fruit, but will also occasionally consume leaves, flowers, and insects.
Due to their large size, spider monkeys require large tracts of moist evergreen forests and prefer undisturbed primary rainforest.
They are social animals and live in bands of up to 35, but will split up to forage during the day.
