In this photo by Rick Rycroft, a baby Western lowland gorilla clings to its mother at Taronga Zoo in Sydney. Frala has kept a tight hold of her baby since it was born last week, and its sex has yet to be determined. The zoo says Frala is an experienced mother with six previous offspring living around the world. It's the zoo's second gorilla baby in seven months, and zookeepers say they'll be future playmates, which is important for learning socialization skills. Primate keeper Lisa Ridley told Australian Broadcasting Corporation, "Having a new baby on board not only strengthens the family group that we've got here, but these guys are ambassadors for their species."
