Q 01In 2023, a viral video led a zoo to deny that its upright-standing sun bear Angela was really what?
A human in costume
A human in costume was the online theory after Angela stood up straight and waved at the crowd. Hangzhou Zoo denied it, and its daily visitor numbers then rose by 30 percent.
Q 02Among the world's eight living bear species, which record belongs to the sun bear?
Smallest
Smallest of the eight, a sun bear is only about half the size of an American black bear. Adults weigh 25 to 65 kg.
Q 03The sun bear holds the bear family record for the longest what, a feature it uses at mealtimes?
Tongue
Tongue length is the record: it slips deep into cracks in tree trunks to lick out insects hiding in the wood.
Q 04Because its tropical home supplies food all year, the sun bear skips which famous bear habit?
Hibernating
Hibernating makes little sense where food never runs out. Sun bears also breed at any time of year instead of in one season.
Q 05What feature gives the sun bear its name, because many think it resembles a rising or setting sun?
Its chest patch
Its chest patch is as individual as a fingerprint, and a threatened sun bear rears up to show it off to an enemy.
Q 06The sun bear's Indonesian name, beruang madu, pairs the word for bear with the word for which food?
Honey
Honey is what the name celebrates, a nod to the animal's habit of feeding straight from honeycombs.
Q 07Adult sun bears signal friendly intent with a contact call that resembles the sound of which bird?
A hen
A hen is the comparison because the friendly call is a soft clucking. Angry sun bears bark, growl and roar instead.
Q 08Hairless soles and strong forelimbs suit the sun bear to which activity, its speciality among bears?
Climbing trees
Climbing trees comes so naturally that sun bears sunbathe and sleep on branches 2 to 7 metres above the ground.
Q 09Sun bear jaws and teeth are strong enough to break open which hard-shelled tropical food?
Coconuts
Coconuts crack under that bite, and the bears also eat the soft centre of the tree itself, which makes them unwelcome on plantations.
Q 10Which big cat is the main natural predator of the sun bear across its forest range?
Tiger
Tiger attacks are the main danger, and one recorded fight went on so long that both animals died.
Q 11Sun bears live wild in the tropical forests of which region, from Myanmar down to Borneo?
Southeast Asia
Southeast Asia is home, with the range running from Bangladesh and Myanmar down to the islands of Indonesia. A 2017 sighting confirmed a few live in China too.
Q 12The Bornean Sun Bear Conservation Centre stands next door to a famous rescue centre for which ape?
Orangutan
Orangutan care at Sepilok was the model for biologist Wong Siew Te, who founded the sun bear centre next door in 2008 with eight confiscated animals.
Q 13With a menu of insects, fruit and the occasional bird or lizard, the sun bear is classed as what?
An omnivore
Q 21Sun bears are poached, and even farmed in some countries, for which body fluid sold as medicine?
Bile
Bile from the gall bladder drives the trade. The giant panda is the only bear spared, because its version lacks the acid that buyers want.
Q 22The IUCN Red List puts the sun bear, down about 35% in number since the 1990s, in which category?
Vulnerable
Vulnerable is the listing, in part because the secretive bears are so hard to count that there is not enough data to class them as endangered.
Q 23Sun bear cubs are born tiny, with closed eyes, and at first they lack which sense?
Hearing
Hearing is missing at birth and sharpens over the first 50 days. The cubs' eyes open at about 25 days, yet they stay blind until day 50.
An omnivore through and through, the sun bear leans on fruit when the forest provides it and turns to insects when fruit runs short.
Q 14Sun bears break open the hard mounds built by which insects, then lick and suck up the contents?
Termites
Termites are eaten fast: the bear holds chunks of the broken mound in its front paws while it feeds.
Q 15Sun bears tear open hollow tree trunks to raid the nests of which stinging insects?
Wild bees
Wild bees are the prize, and the bear rips the hollow trunk apart with its long, sharp claws and teeth to get at the nest.
Q 16Apart from mothers raising cubs, how do wild sun bears usually spend their adult lives?
Living alone
Living alone is the rule, and each adult roams a home range of roughly 7 to 27 square kilometres in Borneo.
Q 17The Asian black bear, a forest neighbour of the sun bear, is nicknamed after which sky object?
The Moon
The Moon gives the Asian black bear its popular name, the moon bear. In mountain forests it outnumbers its sun-named neighbour, probably because there are fewer insects to eat.
Q 18Most bears at the Bornean Sun Bear Conservation Centre arrived after being illegally kept as what?
House pets
House pets is the usual story: cubs are taken from the wild once their mothers are killed, then given up when they grow older and turn hostile.
Q 19By eating fruit and roaming the forest, sun bears perform which helpful job for rainforest trees?
Spreading seeds
Spreading seeds is a real service: a study in Central Borneo found sun bears play an important role in dispersing the tree Canarium pilosum.
Q 20A common nickname for the short-muzzled sun bear says it has the look of which animal?
A dog
A dog lends its name to one of the species' best-known nicknames. The sun bear's muzzle is short and can be grey, silver or orange.
Q 24Sun bear cubs are known for making which contented sound while they nurse from their mother?
Humming
Humming is the nursing sound, and a cub that wants its mother's attention switches to squawks or cries.
Q 25Which term describes the sun bear's distinctive walk, an adaptation to life in the trees?
Pigeon-toed
Pigeon-toed is the word, because the front feet turn inward, a build suited to a life spent among branches.
Q 26A 2019 study of playing sun bears found they precisely mimic which signals from their playmates?
Facial expressions
Facial expressions were mirrored with a precision comparable to that seen in gorillas, more evidence for a species long noted for its intelligence.
Q 27The sun bear's genus name, Helarctos, combines words meaning sun and bear from which language?
Greek
Greek supplies both halves, helios and arctos. Thomas Horsfield coined the genus in 1825 while describing a specimen from Borneo.
Q 28Which of the sun bear's teeth are especially large, helping it rip into hardwood trunks for insects?
Canines
Canines stand out in a jaw with an unusually strong bite for the animal's size: about 2,000 newtons in a bear of 50 kg.
Q 29A captive sun bear watched sugar being locked in a cupboard, then opened the lock using what?
Its claw
Its claw did the job of the key, a feat often cited as evidence of how clever the species is.
Q 30If a predator grabs a sun bear, which feature lets the bear twist around and bite its attacker?
Loose skin
Loose skin lets the bear turn inside its own coat. Its short, sleek fur is also unusually thick, protection against branches, falls and heavy rain.
