The new joey was named Luka, from the Papua New Guinea (PNG) Tok Pisin word “lukuatim,” which means “to take care of” or “to look after.” The name was suggested by the people of PNG’s Huon Peninsula, where the Matschie’s tree kangaroo is an endemic species. “Tree kangaroos mean a lot to those dedicated to saving them in Papua New Guinea, and we chose the joey’s name to reflect our shared work and dedication to saving endangered species around the world,” said keeper Breanne Barney.
