Colophon

The animal on the cover of Calm Technology is a Sunda slow loris (Nycticebus coucang), an arboreal primate found throughout the tropical rainforests of Indonesia, Malaysia, Thailand, and Singapore. These solitary animals are often referred to as malu-malu, the Indonesian word for “shy.”

The Sunda slow loris measures about 11 to 15 inches long. It has a round head with large, dark-rimmed eyes separated by a white strip of fur ending at the nose. Its thick, woolly coat is brown in color, and features a dark stripe that runs from the back of its head along its spine. It also has a vestigial tail.

The slow loris is nocturnal, sleeping on tree branches curled up in a tight ball. Its diet includes tree sap, floral nectar, and fruit. The species is at serious risk of extinction due to hunting for the exotic pet trade and habitat loss.
