5 Amazing Facts about Koala Joeys

1. Baby koalas are called Joeys. All marsupial babies are called joeys – kangaroos, wallabies, wombats, tasmanian devils, possums & bilbys. The meaning/origin is unknown – it’s possibly just a diminutive used at that time for any small animal. Joey as a baby marsupial was first recorded in use in 1839.

The use of the word joey may have started with the word being applied for a British fourpenny coin. Politician Joseph Hume promoted the use of the fourpenny, thus the coin developed the slang name joey after him.

2. The first time you see a koala joey it is already 6 months old. Koala joeys are born as tiny naked creatures that don’t look anything like a koala. They move straight into the pouch, and remain unseen until they emerge at around 6 months old.

Actual emergence takes time. The joey first pokes his head out of the pouch at 5.5 months, and fully emerges at 6 to 7 months. By 8 to 9 months the joey becomes too large to get into the pouch, and spends all his time on his mother’s belly or back.

3. Koalas invented pro-biotics. Koala joeys eat ‘pap’ – a special substance produced by their mother that looks like poo and acts like a probiotic. It contains gut flora that the joey needs to process eucalyptus leaves. The mother koala produces it from her caecum (a special chamber in her large intestine) and delivers it from her cloaca, so though it looks a bit like poo, its not.

Pap is absolutely essential to a koala’s health. Wildlife Carers with orphaned koala joeys will frequently ask the wildlife care community for a postal delivery of pap from a koala mother – any koala mother will do, the closer the better but any is better than none. Imagine receiving that package of squishy green slurry in the mail!

4. Koala joeys are born out of their mother’s central vagina. Female koalas have three vaginas.

Why? Its complicated, and deserves a complete blog on the subject. Suffice to say that the two lateral (side) vaginae are for the passage of sperm to the uteri, and the median (central) vagina is for birth.

5. Koala joeys are born high in a tree. There is no danger of them falling to the ground – they are so tiny they get trapped in their mother’s fur. At birth a koala joey weighs only 1 gram – as much as a single sultana/raisin – and is only 2cm long.
