A dik dik is the world's smallest antelope. Fully grown, they stand only 12-14" tall and weigh between 10-15 pounds. Dik diks live in the bushlands of Eastern and Southern Africa. The males have stumpy, backward sloping horns, often hidden beneath a naturally sassy faux hawk. As you can see, their eyelashes are ridiculous. Below the inside corners of each eye, they have a funny gland that secretes sticky brown goop. Sometimes they jab twigs and grasses into the gland hole to scent-mark their territory. Unlike many antelope, dik diks do not live in herds, but gosh, wouldn't that be amazing? I'd see a dik dik herd and faint immediately from squee exhaustion. Alas, the herd alternative is quite charming: Dik diks are completely monogamous and live together in pairs, forever together, happily ever after, or until one is eaten by a monitor lizard. They are named after the sound of the female's warning calls: "Dik! Dik! Dik! Dik!"
