Q 01What do sea otters wrap themselves in to keep from drifting out to sea while they rest and eat?
Kelp
Sea otters wrap themselves in kelp fronds so they do not drift while resting; they also gather in single-sex groups called rafts that can number dozens of animals.
Q 02Which animal is known for being unable to physically vomit?
Horses
Horses cannot vomit: a powerful lower oesophageal sphincter and the angle at which the oesophagus meets the stomach keep food from coming back up, so digestive trouble quickly becomes colic.
Q 03What is a group of flamingos called?
A flamboyance
A flamboyance it is, though the less showy alternative is a 'stand'.
Q 04How do wombats mark their territory in an unusual way?
They produce cube-shaped droppings
Wombats produce cube-shaped droppings, which they stack on rocks and logs to mark territory; the physics of how the cubes form won Patricia Yang and David Hu a 2019 Ig Nobel Prize.
Q 05Which marine creature has three hearts?
Octopus
An octopus has three hearts: one systemic heart circulates blood around the body while two branchial hearts pump it through the gills.
Q 06Up to how many types of photoreceptor cell can a mantis shrimp have in its eyes?
16
Mantis shrimp eyes can hold up to 16 types of photoreceptor, against three cone types in humans; some species can detect ultraviolet and polarised light.
Q 07What happens to a goldfish if kept in a completely dark room for an extended period?
It fades to almost gray
It fades to almost gray: goldfish produce pigment in response to light, so one kept in darkness gradually loses its orange colour, much as human skin tans in the sun.
Q 08Which bird builds elaborate decorated structures to attract a mate?
Bowerbird
Male bowerbirds build and decorate bowers with berries, shells and even bottle caps; satin bowerbirds favour blue objects, matching the preferences of the females they court.
Q 09Roughly how much of each day does a giant panda spend foraging and eating?
10-16 hours
A giant panda spends 10 to 16 hours a day eating, because bamboo is so low in nutrients; it may consume 9 to 14 kg and defecate up to 40 times daily.
Q 10What unusual defense mechanism do horned lizards use when threatened?
They squirt blood from their eyes
They do it by restricting blood flow leaving the head until tiny vessels around the eyelids rupture; the blood tastes foul to canine and feline predators.
Q 11Which group of mammals sleeps around 18 to 20 hours per day?
Bats
Bats sleep around 18 to 20 hours a day; the little brown bat has been recorded at nearly 20 hours, while giraffes and horses manage on under five.
Q 12The adorable 'sea bunny' that went viral online is actually what type of creature?
A nudibranch (sea slug)
The 'sea bunny' is Jorunna parva, a nudibranch (sea slug) barely 2 cm long; its black-and-white rhinophores look like rabbit ears, and it went viral on Japanese Twitter in 2015.
Q 13What is the collective noun for a group of crows?
A murder
A group of crows is a murder, a term dating from 15th-century English lists of collective nouns; a group of ravens, by contrast, is often called an unkindness.
Q 21What happens to a male anglerfish when it finds a female?
It fuses onto her body
In deep-sea anglerfish the tiny male fuses onto the female's body, his bloodstream joining hers; early scientists mistook attached males for parasites, so the arrangement is called sexual parasitism.
Q 22How do bottlenose dolphins identify and call one another?
With signature whistles
Dolphins have been shown to remember another dolphin's whistle after more than 20 years without contact.
Q 23Which animal can survive being frozen solid and then thawed out?
Wood frog
Q 14Turritopsis dohrnii is nicknamed the 'immortal jellyfish' because, when stressed or old, it can do what?
Revert to its juvenile polyp stage
A stressed, sick or ageing individual can revert to the polyp stage and form a whole new colony.
Q 15How do elephants typically react on finding the remains of a dead elephant?
Gently touching the bones
They show the same interest in the bones of unrelated elephants that died long ago.
Q 16Which animal can rotate its head nearly 270 degrees in either direction?
Owl
Owls can turn their heads about 270 degrees; they have 14 neck vertebrae to our seven, and oversized artery channels keep blood flowing to the brain mid-turn.
Q 17What unusual ability do flatworms have if cut in half?
Both halves regenerate into complete worms
Both halves regenerate into complete worms, and pieces as small as 1/279th of the animal can regrow, which is why planarians are called 'immortal under the edge of a knife'.
Q 18What color is a hippo's sweat?
Red
Two acidic pigments in the secretion, one red and one orange, inhibit bacteria and absorb ultraviolet light, giving a sunscreen effect.
Q 19Which animal's fingerprints are close enough to ours to confuse crime scene investigators?
Koalas
It is a striking case of convergent evolution: koalas are marsupials, and their prints likely evolved for gripping branches.
Q 20What is a baby kangaroo called?
Joey
A baby kangaroo is a joey; born about the size of a jellybean, it crawls into its mother's pouch and stays there for roughly six months.
The wood frog freezes solid each winter with no heartbeat, breathing or detectable brain activity; glucose acts as antifreeze in its cells, and it thaws and hops away in spring.
Q 24Which microscopic animal, sometimes called a water bear, has survived direct exposure to outer space?
Tardigrade
Tardigrades, or water bears, survived 10 days in open space on the 2007 FOTON-M3 mission; in their dried-out 'tun' state they withstand vacuum, radiation and temperatures from -272 °C to 149 °C.
Q 25What peculiar activity have crows been observed doing for apparent enjoyment?
Sliding down snowy roofs on lids
A hooded crow in Russia was filmed riding a jar lid down a snowy roof, then carrying it back up to go again.
Q 26Which insect can pull over 1,100 times its own body mass?
Dung beetle
Onthophagus taurus, the bull-headed dung beetle, holds the record; the horns on males are used to fight rivals in tunnels.
Q 27What body part does a butterfly use to taste things?
Its feet
The receptors work only on contact, so landing on a leaf tells a female whether her caterpillars could eat it.
Q 28Which waxy substance from a sperm whale's gut was prized by perfumers?
Ambergris
Ambergris forms around squid beaks in a sperm whale's intestines; after years floating in the ocean it develops an earthy scent prized by perfumers as a fixative.
Q 29Which burrowing rodent feels no skin pain and resists cancer and oxygen deprivation?
Naked mole-rat
The naked mole-rat lacks the neurotransmitter that signals skin pain, almost never develops cancer and has survived 18 minutes without oxygen; its oxygen-hungry haemoglobin suits crowded, stuffy tunnels.
Q 30Thanks to a shared taste-receptor gene mutation, which flavour can cats not detect at all?
Sweet
Cats cannot taste sweet: a defect in the Tas1r2 gene leaves them without a working sweet receptor, so they are indifferent to sugar; their umami and bitter receptors still work.
