Which animal smells like popcorn

But for many zookeepers, the smell wafting from the binturong enclosure is so striking that they name their resident binturongs after the popular snack. In a paper appearing online in the journal The Science of Nature - Naturwissenschaften, researchers analyzed urine samples collected during routine physical examinations of 33 binturongs at Carolina Tiger Rescue , a nonprofit wildlife sanctuary in Pittsboro, North Carolina.

Binturongs pee in a squatting position, soaking their feet and bushy tails in the process. They also drag their tails as they move about in the trees, leaving a scent trail on the branches and leaves behind them. The one compound that emanated from every sample was 2-acetylpyrroline, or 2-AP -- the same compound that gives popcorn its tantalizing scent.

Males secrete more 2-AP than females. The compound 2-AP normally forms in popcorn during the popping process, when heat kicks off reactions between sugars and amino acids in the corn kernels. The cooking produces a variety of new odor and flavor molecules in a chemical reaction called the Maillard reaction. The same compound is also responsible for the comforting aromas of toasted bread and cooked rice.

But there is some evidence that the smelt may be staging a small comeback. A study revealed an increase in healthy juvenile Delta smelt in a region that provided a protective habitat for these small creatures. This flightless nocturnal parrot has a strong odor that, unfortunately, makes it easy for introduced predators to find it. Some say it has a sweet, musky smell like honey. Others, like biologist Jim Briskie of Canterbury University in Christchurch, believes they smell like musty violin cases.

While smell is subjective, it has also been one factor in the precipitous decline of the kakapo since the introduction of rats, cats, and stoats to their island homes. The critically endangered kakapo has so much trouble with strong-smelling nests that biologists are considering using a deodorant around their nests to better hide chicks and eggs from predators.

The relaxing scent of lavender is a good smell to have in your bedroom, as is the calming scent of sandalwood, or perhaps sage. What is not a good smell to have in your bedroom is coriander. If you catch a whiff of this spice, it's time to call an exterminator. If you have a large concentration of bed bugs, the smell can move beyond coriander and into the realm of musty gym shoes.

There are several differences between male and female western grey kangaroos. Males are larger, have more muscle mass, and consume more grass than their female counterparts. However, the most unique difference between the two is the unusual scent that only the male of this species can claim: curry.

This spicy scent has given the male western grey kangaroo his own special nickname as well, stinker. Honey bees, including Africanized honey bees, release an alarm pheromone that smells like bananas. And if you're close enough to a bee to smell this, you might be in a spot of trouble.

The pheromone attracts other bees to respond to the potential danger. If you're stung by a honey bee, you definitely need to wash your clothes because the pheromone can stay on clothing. In other words, if you're near bees and smell bananas, it's time to put yourself on alert as well. Crested auklets give off a strong smell of a favorite citrus fruit, the tangerine.

According to Hector Douglas, Ph. Research further reveals that the monogamous birds emit the tangerine scent during courtship. Crested auklets are well known for their "ruff-sniff" mating ritual in which both partners press their bill and face into the feathers of their mate.

Millipedes are truly creepy critters, but they also have a sweet smell. Except that smell comes from a toxin. The yellow-spotted millipede Harpaphe haydeniana is also known as the almond-scented millipede, the cherry millipede, and the cyanide millipede because of the smell of hydrogen cyanide it exudes as a defense.

This chemical smells just like almonds or, to some, cherry cola. The secretion is foul tasting and allows the millipede to escape from predators when they wise up and spit the bug out. Making text-to-text connections builds knowledge and comprehension.
