A very strange occurrence at the Oklahoma City Zoo and Botanical Gardens. Apparently, one of the lionesses in captivity, grew a small mane. It is an African lioness at the age of 18 years.
Manes are a male characteristic, and lions start to grow a mane at the age of 1 year when they start producing higher quantities of the hormone testosterone. It is tremendously rare for a lioness to grow one.
Veterinarians and Zoo officials started an investigation to find out the reasons behind this, so a blood sample was taken from the lioness Bridget and they are currently waiting for the results.
The possible outcome for an occurrence like this can be a hormonal imbalance, due to reproductive tumors or cysts (polycystic ovary syndrome), or bad diet which can result with a imbalance in the sex hormones.
