Do animals that hibernate, urinate?

Probably not as their bodies use only the energy(fat) they need to survive the long sleep.

It would be a cold blooded animal, meaning it has no homeostatic mechanisms to regulate it's temperature (where warm blooded animals do things like sweat to cool them down, or shiver to warm them up). \nThe scientific name for a cold blooded animal is an 'ectotherm'.

Very few mammals actually hibernate.  Only a few small rodents that live in the far north (such as some ground squirrels) undergo a seasonal estivation during the winter.\n\nEven most arctic mammals remain active all year long.  Polar bear, caribou, arctic fox, bison, meadow voles, lynx, snowshoe hares, etc. etc. all live quite well through the winter.\n\nSome bears (black bears, brown bears) enter a state of torpor through the winter, but even they do not truly hibernate.\n\nAnother reason humans don't hibernate is that we didn't evolve in a cold climate where hibernation would be advantageous. \n\nHomo sapiens sapiens evolved in sub-Saharan Africa, and there are few cold winters there (even during Ice Ages).  The only way we can survive in northern climates is through our learned adaptations of technology:  fire, and clothing.\n\nLynx and wolves live and hunt all winter long without any clothes, and large herbivores like bison and caribou don't even have shelter.  How long do you think humans would last in Canada if they were naked and couldn't build a fire?\n\nOur niche is the savannahs of Africa.  People can (and do) survive quite nicely there without much in the way of clothing.  It's one of the reasons we prefer a room temperature around 22 C.  It could also be why we like having an expanse of short cropped grass dotted with one or two trees in front of our caves.\n\nWe evolved to fit into that particular ecological niche, and were able to adapt other niches to meet our needs with our technology.

1)  By producing heat, organisms can stay active throughout the cold winter months, thereby allowing them to breed and claim new habitats.  They can also feed on the slower, cold-blooded creatures!\n\n2)  Warm-blooded animals can stay more active during night time hours - an advantage for many of the same reasons in (1).\n\n3)  Warm-blooded animals can change their metabolisms much faster than can cold-blooded animals.  This allows them to adapt to environments and to increase their range.  Cold-blooded animals are much slower to adapt to changing environmental conditions.\n\n4)  Exothermic reactions within the body allow for greater metabolic efficiency.  Therefore, warm-blooded animals get greater benefit from the food that they eat, or conversely, do not need to eat as often to get their nutrional requirements.  This gives them an evolutionary advantage in terms of what they can eat and the ability to thrive during famine.

Yes very much. My dogs always seem to drink as soon as I am about to fall asleep. Them panting also annoys me. They get on my bed and pant. The entire bed shakes. They are 130 lbs and 65 lbs) the 65 lb one is 9 months though so getting bigger. I am just rambling but you asked about hat and the lapping made me think of the panting. Also I hate the nasty slippery drips from the water bowl when they are done drinking. It is like teflon. They will also drink out of the toilet. It is like a guy peeing on the seat, but you can't see it before you sit. It is really nasty.

Dolphins are conscious breathers: They have to actively decide when to breathe. Consequently, in order to breathe, they have to be conscious. \n\nSo to breath and to sleep, dolphins let one half of the brain sleep at a time. In this way, the animal is never completely unconscious, but it still gets the rest it needs. In their sleep cycle, half of the dolphin's brain does indeed "shut down" while the other half is still active. \n\nThey could probably sleep anywhere, but it makes sense that they would do it near the surface of the ocean so they can come up for air easily. It's not uncommon to see dolphins "logging," swimming slowly along the surface, with very little movement. Presumably, these are dolphins at rest.♥

Hmm lets see... an amphibian is cold blooded....  (think lizards and crocodiles), so the best answer here is probably a heated chair.  Amphibian would be likely to want to sit on something warm.\n\nA heated rock chair?  THey like sitting on rocks!  lol  good luck

I am unsure if it sleeps.\nHowever, its lifespan is not long so it probably does not need sleep and yawn.

They group together within their nest/mound and go into something called "diapause," which is the insect equivalent of hibernation. Their bodies freeze and they just shut down and become active again once the temperatures reach a warm enough level.

THeir fur is actually colorless, it absorbs light to heat their bodies.  It works so well, that they frequently have to swim in freezing waters to cool down or roll around in the snow.  They aren't very active either becasue then they would overheat.

Animals take in Oxygen and give off Carbon Dioxide.\n\nPlants do the opposite.

Skunks is different from other animals and they do not hibernate but become temporarily dormant during severe winter season. Which means, they don't sleep throughout the winter season. They come out when they can handle the cold.\n\nSkunks are omnivores. They feed on various insects and grubs (grasshoppers, beetles, bee larvae), small mammals, the eggs of ground-nesting birds and amphibians. Skunks are especially fond of spiders, snails, ants, wasps, and crayfish. For the whole year, they eat fruits and berries: cherries, raspberries, strawberries, apples and pears.

When fall turns to winter and the temperature dips, the food sources for the wild animals becomes very scarce.  Some animals wait out the harsh conditions of winter, constantly searching for food and shelter.  Other animals, like the bear, spend the winter in hibernation. \n     Hibernation is a dormant sleep-like state.  By going into hibernation the bears bypass winter when their food supply, nuts and berries, disappears.  Animals like the bear would find it extremely difficult to find enough food during winter, and therefore go into hibernation. \n\n     During hibernation the bear cuddles up in a cave or in a hollowed out tree, safe from the dangers of winter.  In order to survive this long period of inactivity the bear must build up its body weight by accumulating fat.  In the months before  hibernation bears can gain up to forty pounds of fat per week.   A bear’s body goes through several changes once it enters hibernation.  Its heartbeat drops from fifty-five beats per minute to ten beats per minute, and the bear’s body temperature will drop from five to nine degrees below normal.  While in hibernation the bear uses  the stored energy it accumulated as fat to survive.  So a bear can lose from fifteen to forty percent of its body weight during the winter just by sleeping! \n\n     Bears will generally enter hibernation in early October and emerge sometime in April or May, when their food is plentiful again.  The hibernation cycle is just another unique adaptation of nature that allows many animals like the bear to survive during the severe conditions of winter time. \n\nhope this helps.

Hybernation is a particular form of torpor, a state of reduced metabolism and low activity.  In this the body temperature of the animal drops almost to ambient temperature but periodically spikes up to its normal value.  The reason is indeed to preserve energy in a time when food resources are scarce.  Bears thereby can survive on a very low metabolic rate.  This way they can manage to spend the winter months without having to find the otherwise needed amount of food.\n\nFootnote:  It is NOT a state of sleep these animals are in, but indeed a state of extremely reduced metabolism and activity.  Different from other forms of torpor is here that the animal's body temp now and then spikes up, in other word, that the animal now and then indeed metabolizes.\n\nHope that helps.

Yes, there are actually quite a few insects and animals that don't drink water.  They get the water they need from the food and plants that they consume.  Very handy for desert animals.

Mostly, they don't unless their in zoos.  Once there habitat is gone, they're gone.  Squirrels are the exception.
