156 articlesPepper plants are perennial in their native tropical range and are grown as annuals in temperate gardens because frost kills them before they can complete a second season.
Let's find outAn ox is not the same as a cow. In strict biological terms, both are domesticated cattle (Bos taurus), so they belong to the same species, but the words describe different categories.
Let's find outYes, pet monkeys are dangerous, and the risk is structural rather than a matter of bad training.
Let's find outYes, penguins are intelligent, but in a domain-specific way that confounds the standard primate yardstick.
Let's find outYes, peanuts are legumes, not nuts. A peanut is the seed of Arachis hypogaea, a plant in the Fabaceae (legume) family, and it develops inside a pod that splits along a seam exactly as a pea pod does.
Let's find outYes, penguins are endangered in a precise, partial sense: of the 18 recognized penguin species, 5 are listed as Endangered or Critically Endangered and 5 more as Vulnerable on the IUCN Red List, while 7 remain Least Concern and 1 is Near…
Let's find outNorthern catalpa beans are toxic and should not be eaten. The long, cigar-shaped pods contain catalpin, catalposide, and other iridoid glycosides that cause vomiting, diarrhea, and abdominal pain in people.
Let's find outYes, onion greens are edible. The green, hollow, tube-shaped leaves that sprout from every onion bulb are the same plant tissue as the common scallion, and they can be eaten raw, sautéed, or used as a garnish.
Let's find outMountain goats are not friendly in the way pets are friendly. They are tolerant, curious, and highly food-motivated, but they are wild animals that can become aggressive when habituated to people.
Let's find outMushrooms are neither fruit nor vegetable. They belong to their own kingdom, Fungi, which split from animals roughly 1.1 billion years ago, and the part you eat is a reproductive structure called a fruiting body, closer in biology to a…
Let's find outYes, mums are toxic to animals, and the toxic principle is a family of compounds called pyrethrins that chrysanthemums evolved as an insecticide.
Let's find outAre marine reserves worth it? Yes, on balance, with hard limits.
Let's find outAre minks invasive? Yes — in much of Europe and parts of South America, the American mink (Neovison vison, now often classified as Neogale vison) is a confirmed invasive alien species, while the native European mink is itself endangered.
Let's find outNo, lily pads and lotus flowers are not the same. A lily pad is the floating leaf of a water lily (family Nymphaeaceae, genus Nymphaea or Nuphar), while a lotus flower is the bloom of Nelumbo nucifera or Nelumbo lutea (family…
Let's find outNo, hummingbird moths are not dangerous. They have no stinger, no venom, and no biting mouthparts capable of breaking human skin; the worst realistic outcome is a mild, temporary skin irritation from hair-like scales if you handle one…
Let's find outNo, humans are not the only animals that cry, but the distinction depends entirely on which tears you mean. Only humans reliably produce emotional tears, the weeping that follows grief or joy.
Let's find outYes, insects are animals. Insects belong to the kingdom Animalia, the class Insecta within the phylum Arthropoda, and they share with all other animals the defining traits of multicellularity, specialized tissues, and heterotrophy, meaning…
Let's find outAre cats easy to take care of? Yes, relative to most pets, and the honest reason is behavioral: a healthy adult cat needs roughly 15 to 30 minutes of active human attention daily, self-regulates its own eating and elimination, and…
Let's find outGreen lynx spiders are venomous but not poisonous: their venom is delivered by bite into prey or skin, not absorbed by eating them, and it is medically minor for humans.
Let's find outYes, hernias are common in puppies, but the word "common" hides a huge split.
Let's find outChimpanzees and gorillas are differently smart rather than one being smarter overall: chimps outperform gorillas in social learning, tool use, and working memory, while gorillas hold their own in emotional intelligence, spatial reasoning,…
Let's find outYes, goldfish are schooling fish, but not in the strict, obligate sense that many saltwater species are.
Let's find outYes, figs are inverted flowers. The fig you eat is a hollow, pear-shaped stem structure called a syconium, and its inner wall is lined with hundreds to thousands of tiny flowers that bloom entirely enclosed.
Let's find outAre dog breeders bad? Not inherently, no. Whether a breeder is harmful depends almost entirely on practice, not on the label.
Let's find outYes, crabapples are actually apples. Every crabapple is a true apple in the botanical sense: both belong to the genus *Malus* in the rose family, and the crabapple is simply any *Malus* species or variety that produces small fruit,…
Let's find outMost circus animals are not treated well, and the modern traveling circus is the worst-case setting in the industry.
Let's find outAre deer blocks good for deer and are they safe? The short answer is that deer blocks are conditionally useful, not universally good.
Let's find outAre cats selfish? No — not in any scientifically meaningful sense. What looks like selfishness is a mismatch between feline social evolution and human expectations.
Let's find outNo, blue-tailed skinks are not poisonous. They have no venom glands, no toxin-producing skin, and no bite capable of delivering poison to a human. The bright blue tail is a visual decoy, not a chemical weapon.
Let's find outAre Cape Buffalo endangered? No. The Cape buffalo (*Syncerus caffer caffer*) is classified as Least Concern on the IUCN Red List, with a continental population estimated at roughly 830,000 to 900,000 mature animals.
Let's find outAre Bulldogs lazy? Yes, on average, but not because they are stubborn or unmotivated. The typical adult Bulldog sleeps 12 to 14 hours per day and naps another 2 to 4, roughly 40 percent more rest than a comparably sized herding breed.
Let's find outBlue Jays are not endangered. They are classified as a species of least concern by the IUCN, with an estimated global breeding population of roughly 14 million and a stable-to-increasing trend across most of their range.
Let's find outNo, beetles are not blind. Almost all of the roughly 400,000 described beetle species have functional eyes, and most are compound eyes made of hundreds to thousands of individual lenses called ommatidia.
Let's find outAre bullet ants deadly? No — there is no documented record of a human death caused solely by a bullet ant sting.
Let's find outNo essential oil is proven safe for routine use on or around reptiles, and several common ones are actively dangerous.
Let's find outNo, black bears are not territorial. They do not defend exclusive home ranges against intruders. Instead, black bears share overlapping home ranges and rely on a dominance hierarchy and scent-based time-sharing to avoid conflict.
Let's find outYes, dog breeds are banned in the United States, but no federal law bans any breed.
Let's find outAnimal respiratory systems are the biological equipment that moves oxygen from the environment into the body and carbon dioxide out, and they take four main forms: gills in water breathers, lungs in air breathers, tracheal tubes in…
Let's find outAmerican bullfrogs are not poisonous and are not dangerous to humans in any life stage. Their skin carries no toxins, they have no venom glands, and they cannot bite hard enough to break skin.
Let's find outYes, white tigers are effectively extinct in the wild, and the deeper truth is that the animal most people picture is not a separate endangered species at all.
Let's find outThe ash tree root system is a shallow, wide-spreading network of woody roots and fine feeder roots that typically occupies the top 18 to 24 inches of soil and extends 1.5 to 3 times the radius of the canopy, with most structural roots…
Let's find outArborvitae trees need roughly 1 inch of water per week, delivered slowly to the root zone, with the first two growing seasons being the most critical. Water deeply once or twice weekly rather than lightly and often.
Let's find outHuntsman spiders are venomous but not dangerous to humans. Their venom is a fast-acting neurotoxin built to paralyze insects and small vertebrates, and it is far too weak to threaten a person.
Let's find outYes, black-footed yellow sac spiders are venomous — almost every spider is — but their venom is weak against humans and a bite is rarely dangerous.
Let's find outAre cosmos flowers edible? Yes, the petals of Cosmos bipinnatus and Cosmos sulphureus are edible and have been used as a mild garnish for centuries, but the plant is not a food crop and comes with real caveats.
Let's find outBrown centipedes (Lithobius forficatus, the stone centipede) are not dangerous to humans in any medically meaningful sense.
Let's find outYes, the blue whale is larger than any dinosaur that ever lived, and it holds that record in two separate ways.
Let's find outNo, hyenas are not mean in any meaningful sense. They are not cruel, spiteful, or malicious, because those words describe intent, and intent requires a kind of cognition hyenas do not have.
Let's find out
