Do insects smell? Hear? Taste?

Yes, no and yes.\nThe hearing part is really sensing vibrations, but they don't ACTUALLY hear.

Yes many a times fart sound like words. Its like imagining shapes in the clouds. You hear what you want to hear. If you are about to propose you hear 'YESSSSSSSSS" farts, a child is asked about a sheep, he hears the 'BAAAA' farts, if u are seeing a film on snakes u hear 'HISSSSSSSSSSS" farts

Of course it does. Sound waves are generated, and just because there is no one to hear does not they don't exist.\n\nIf a bear poops in the woods and no one is there to smell it, does it still stink?

Most of the odour comes from molecules released by bacteria in the gut.  Some are facultative; they can live with or without oxygen.  Some of these release hydrogen disulfide (rotten egg gas.)\n\nOthers are anaerobes; they live only in the absence of oxygen.  Many of these release fatty acids and amines from the larger molecules they digest for food; fats, proteins, nucleic acid, etc.  Some fatty acids are very pungent; some smell like butter, or strong cheese, or dog faeces etc.\n\nThe anaerobes are even pungent if cultured in our laboratory!  When we are culturing from some samples, the stinky ones generally contain anaerobes.  A good sense of smell is very handy in Clinical Microbiology.\n\nYears ago, I read research (that was done in inbred mice strains) showing that the genes of the animal had an influence on the types of bacteria that remained in its gut.  They said this was part of the reason why different strains of mice could recognise close relatives by smell; genes resulted in smells.\n\nI think this explains why different people make different odours, though fed the same foods.

Sight, smell, hearing, touch, taste .....\n\nSIGHT --Looked around the room\nSMELL -- the putrid odor of old sweaty socks\nHEARING -- could hear the lost hamster scampering across the pile of potato chip bags\nTOUCH -- was repulsed at the slimy feel of the rotten apple\nTASTE -- but the unopened soda was quickly opened to quench my thirst\n\nA few starters ..... now get busy !!!!!

Oooh...sounds like ants to me.

A quick question with a quick answer: They're not blind.\n\nBut if you're still curious if they use it to navigate around... No.\n\nThey use their hypersensitive antennae to navigate, distiguish objects, detect vibrations and find their food.\n\nA cockroach with its antennae cut off will die of starvation.\n\nI do this ALLLLLLLLLLL THE TIME!!!!\n\nAND ITS FEEEEEEEEELLS SO GOOOOOOOOD!!!\n\nYucky creepy bastards!

Can you smell what the Rock is cooking?

I know ants are not (I tried it out). The sugar receptors of bugs are not the same than ours, so while they get stimulated by sugar, they not necessarily stimulated by other molecules we perceive as sweet.

You smell bad?  Maybe some food?  Who knows?  Hold your ear real close to a fly and ask him.

Maybe you're not very tasty!!\n\nWhy are some people more attractive to mosquitoes then others? Scientists are still investigating the complexities involved with mosquito host acceptance and rejection. Some people are highly attractive to mosquitoes and others are rarely bothered. Mosquitoes have specific requirements to satisfy and process many different factors before they feed. Many of the mosquito's physiological demands are poorly understood and many of the processes they use to evaluate potential blood meal hosts remain a mystery. Female mosquitoes use the CO2 we exhale as their primary cue to our location. A host seeking mosquito is guided to our skin by following the slip stream of CO2 that exudes from our breath. Once they have landed, they rely on a number of short range attractants to determine if we are an acceptable blood meal host. Folic acid is one chemical that appears to be particularly important. Fragrances from hair sprays, perfumes, deodorants and soap can cover these chemical cues. They can also function to either enhance or repel the host seeking drive. Dark colors capture heat and make most people more attractive to mosquitoes. Light colors refract heat and are generally less attractive. Detergents, fabric softeners, perfumes and body odor can counteract the effects of color. In most cases, only the mosquito knows why one person is more attractive than another.

Yes the beetle is an insect.\n\nGood rule to help you identify insect in the future, \n\nIf it has 6 legs, antennae and mandibles chances are it is an insect

Scientists are still trying to decipher exactly what is the mechanism by which we taste and smell.  But this we do know: vapors from the substance in question enter the nose and interact with receptor sites there that are keyed to specific responses in the brain.  The combination of the receptor sites that are activated by the vapor generate a signal that the brain interprets as "smell"/"odor"/"aroma" (take your pick).\n\nThink of the various smells you exerience each day -- pears have an ester known as n-amyl acetate that generates that characteristic smell.  Iso-amyl acetate smells like bananas.  \n\nAnd then there are the fouls smelling compounds -- usually containing sulfur -- such as hydrogen sulfide (rotten eggs), or  methanethiol (or methyl mercaptan) -- which is used to generate the smell in natural gas (which is otherwise odorless), or butanethiol -- skunk spray!\n\nAmines typically have a fishy, musty odor.  Fatty acids tend to have a rancid smell.\n\nEach of the chemicals I have mentioned has a variety of chemical structures, and some similarities: the thiols all have a -SH group in the molecule somewhere, which interacts with receptors in our noses to send a signal to the brain of YUCK!! NASTY!!  Most esters have a pleasant, fruity smell -- there, the characteristic group is R-C(O)O-R'.  Primary amines have the R-NH2 structure, secondary amines replace 2 hydrogens with organic groups, and tertiary amines replace all three hydrogens with organic groups, but they all have that nitrogen in there. \n\nI hope that helps.

Crabs have innervated sensilla or setae that cover their body and appendages; some of these are mechanoreceptors that can sense touch and currents, including vibrations (sound waves). \nAt least for shrimps, their statocyst (equilibrium organ) has been demonstrated to be also a hearing organ (see the scientific paper at the link).\nThe sea is filled with sound, as sound vibrations travel exceptionally well in the aquatic medium. In addition, several crustaceans produce sounds themselves. Therefore it's only logical that they have evolved sound receptors of different types.

Most dolphins have acute eyesight both in and out of the water and their sense of hearing is superior to that of humans. Though they have a small ear opening on each side of their head it is believed hearing underwater is also if not exclusively done with the lower jaw which conducts the vibrations to the middle ear via a fat filled cavity in the lower jaw bone. Hearing is also used for echolocation which seems to be an ability all dolphins have. The dolphin's sense of touch is also well-developed.\n\nHowever, dolphins lack an olfactory nerve and thus have no sense of smell, but they can taste and do show preferences for certain kinds of fish. Since dolphins spend most of their time below the surface in the wild, just tasting the water could act in a manner analogous to a sense of smell.

smell pepper or any thing really REALLY scpicy
