Creatures & Their Records
The biggest, the fastest and the genuinely strange.
Which vertebrate is believed to have the longest lifespan?
Predators are talked about more than almost any other group of animals, which means plenty of what gets repeated about them is decades out of date. These ten stick to what is well established.
Hunting is an expensive way to make a living, and it shows in the anatomy. A cheetah gave up retractable claws for grip. A leopard developed the neck and shoulders to haul a carcass up a tree. A polar bear traded the omnivore diet of every other bear for a life spent waiting at a hole in the ice. This quiz covers the cats first, since that is where most of the confusion sits, then widens out to wolves, hyenas, snakes and the largest dolphin in the sea. Several answers overturn something people are fairly sure they already know, and the explanations say where the old idea came from.
Every question in this quiz is listed below with its correct answer and the reasoning behind it. Play first if you would rather not see the answers — or read through as a study sheet.
Play it insteadAnswer: B. Tiger
Why: Tigers are the heaviest living cat species, with the Siberian and Bengal populations at the top end. A tiger's stripes grow from pigmented skin, so the pattern would still be there if you shaved one.
Answer: A. Cheetah
Why: The cheetah's claws stay semi-extended and dig in like a sprinter's spikes. Cheetahs also cannot roar, which is why they chirp, yelp and purr instead.
Answer: D. Its rosettes have small spots inside them
Why: A jaguar's rosettes enclose one or more small dots, while a leopard's are empty in the middle. The jaguar is also the stockier animal and the only big cat native to the Americas.
Answer: C. Polar bear
Why: Polar bears feed mainly on seals and are classed as marine mammals because of how completely they depend on sea ice. Their hairs carry no white pigment at all, and the skin underneath is black.
Answer: B. The dolphins
Why: Orcas are dolphins, despite the name. Groups hunt in ways that are learned rather than instinctive, and separate populations use distinct calls that pass down the generations.
Answer: A. Reticulated python
Why: The reticulated python of Southeast Asia is the longest; the green anaconda is shorter but far heavier. The king cobra holds a narrower title as the longest venomous snake.
Answer: D. A breeding pair and their offspring
Why: Most wild packs are simply a family: two parents and the young of one or more years. The old idea of an alpha wolf fighting its way to the top came from studies of unrelated captive animals thrown together in an enclosure.
Answer: C. Snow leopard
Why: Snow leopards live on the steep ground of the Central and South Asian ranges, where a tail nearly as long as the body earns its keep. They cannot roar either, despite the name.
Answer: B. Leopard
Why: Leopards cache carcasses in branches to keep them away from lions and hyenas, and can haul prey heavier than themselves. It is one reason leopards survive alongside larger competitors.
Answer: A. The cat-like branch, alongside mongooses and civets
Why: Hyenas look dog-like but belong to the feliform side of the order, closer to cats, mongooses and civets. Their clans are led by females, and every adult female outranks every male.
