The Odd Family Out Trivia Quiz

Answer: Megalonychidae

Of course, the Marsupialia infraclass contains marsupials, mammals that have pouches. Koalas are in there under Phascolarctidae, so are kangaroos, wallabies and pademelons in Macropodidae, and our burrowing friends the wombats are part of the Vombatidae family. So, the odd one out is Megalonychidae, which is a family of the order Pilosa containing two-toed sloths.

Answer: Viverridae

Primates contains all the monkeys, apes, lemurs and other relatives you care to think of. Included in this order is the family Hominidae, which should be familiar as that is where humans come under! Daubentoniidae is the family under which aye-ayes (and the extinct giant aye-aye) fall. Marmosets and tamarins are part of the Callitrichidae family, notable for being the smallest of the simian primates.

This means that the odd family out in this group is Viverridae, of the order Carnivora. Viverridae is the family of which the binturong, civets and other relatives are a part of.

Answer: Orycteropodidae

Ah, the even-toed ungulates of the Artiodactyla order. Some of the most recognisible mammals of the animal kingdom reside in this order. Giraffidae is the home to the giraffe and okapi, the only two living members of this family today. So too is the family Antilocapridae, with the pronghorn being the only species still alive.

The all-too-familiar bison, antelopes, buffalo, gazelles, sheep and cattle are part of the Bovidae family, being widespread across the globe. It seems that the Orycteropodidae family is the odd one out in this set, containing Arthur himself, the aardvark. Aardvarks are part of the Tubulidentata order.

Answer: Trichechidae

Monodontidae, as its name should hint at, contains the fascinating creature known as the Narwhal, as well as the Beluga. Sperm whales fall under the family of Physeteridae, which is part of the superfamily Physeteroidea. The family Phocoenidae contains the porpoise, a close relative of the dolphin. Alas, the Trichechidae family is the odd one out.

The friendly manatees are part of this family, but fall under the order of Sirenia.

Answer: Procaviidae

The Castoridae family, containing beavers, is part of the Rodentia order. So is Hydrochaeridae, which contains the largest rodent in the world, the capybara. Also falling under the order of Rodentia is the Muridae family, which also happens to be the largest family of mammals, containing mice, rats and other such relatives. Hyraxes, native to the Middle East and Africa, are a part of the Procaviidae family, but they come under the order of Hyracoidea, and therefore are the odd family out.

Answer: Hylobatidae

I hope this order doesn't drive you batty, because this one focuses on bats. The Pteropodidae family is known for fruit bats and flying foxes. Not the most well-known of the bats, but certainly not to be overlooked, the Mystacinidae family contains the New Zealand short-tailed bats, who spend significantly less time in the air than their other bat cousins.

The bats we see coming out at nighttime in flocks is the common evening bat, or the Vesper bat, from the Vespertilionidae family. Despite sounding like it might be part of the Chiroptera order, the Hylobatidae family is in fact part of the Primates order, containing gibbons.

Answer: Leporidae

Raccoons and their relatives (including some lesser-known creatures like the kinkajou and olingo) form the Procyonidae family. The Otariidae family contains sealions, the fishy-kissers of the Carnivora order. Also forming part of this order is the Herpestidae family, known for the mongoose. That means that Leporidae is the odd family out.

The Leporidae family contains rabbits and hares, and they fall under the order of Lagomorpha.

Answer: Tachyglossidae

The order Pilosa contains the placental mammals. The Myrmecophagidae family contains anteaters, the Bradypodidae family contains the tree-dwelling, slow-moving three-toed sloths, and the Megalonychidae family, which we encountered right back in the very first question, contains the two-toed sloths.

The family Tachyglossidae contains the echidna, who is one of only two living members of the Monotremata order.

Answer: Manidae

Solenodons are, not surprisingly, part of the Solenodontidae family. Other families in the Soricomorpha order are Soricidae, which contains shrews, and Talpidae, the family containing the mole and its relatives. The family Manidae is not part of the Soricomorpha order. Manidae contains the pangolin, which is part of the Pholidota order.

Answer: Suidae

The three families that are a part of the Perissodactyla order are Equidae, Tapiridae and Rhinocerotidae. The Equidae family contains horses, donkeys, zebras and other related odd-toed ungulates. Tapirs fall under the family of Tapiridae, and rhinoceri are, believe it or not, part of the Rhinocerotidae family. Thus, the odd family out here is Suidae.

The Suidae family is part of the Artiodactyla order, and contains pigs and its relatives.
