are fish warm blooded?

No!\nCold-blooded animals, such as fish and reptiles, are called ectotherms, meaning that they cannot control their internal temperature.

um....there are a lot of them.\none example is the snake.  It is a mammal, and it's warm-blooded, and it doesn't have legs.  The fish family do not have legs and they aren't mammals and they're cold-blooded. If you're looking up a certain animal, just identify some of its characteristics and try to make sense out of it.

The first thing you need to know is fish live in water, so you fish in water not sand.

because of all the energy that your muscles use, turns into 25% motion, and 75% heat. our body does that so we can be mammals. cold blooded animals convert 100% into motion, hence, they create no heat. however, we cannot bypass this mechinism because it is necisary for life.

In fish, the circulatory system has only one circuit, with the blood being pumped through the capillaries of the gills and on to the capillaries of the body tissues. This is known as single circulation. The heart of fish is therefore only a single pump (consisting of two chambers).\nSee ilustration in \nhttp://www.emc.maricopa.edu/faculty/farabee/biobk/BioBookcircSYS.html

They have fur, they deliver their young and don't lay eggs, they're warm blooded.

Ichthyosaurs are reptiles,which mean they do not have a constant body temperature like we humans do.They probably live in a clmate that's not too hot or too cold.If it's too hot or cold,the ichthyosaur would not be able to control its body temperature and die.They live their entire lives in water.

The main differance as the stinging spine on  the tail of the stingray, also (i'm not sure about this, just going on experience)  stingrays seem to prefer warmer soputh waters, skates liking the more northerly, I used to live in NY and commonly fished in Maine and Mass and caught lots of skate, but since moving to florida I have caught only stingrays. And like the guy above said, stingray tastes a lot like scallops if cooked right, don't know about skate, never bothered to eat one

Birds, Definitely. birds, being warm blooded, are much closer to mammals than amphibians. Amphibians only show the faintest glimmer of an R-Complex, known in your brain as a cerebellum - the reptilian part of the brain. Birds, by contrast, have a highly developed R-complex and even show the beginnings of a cerebrum (the big lumpy part of your brain that handles all that rational though stuff). Can you imagine a frog or a salamander uttering, "Polly wants a cracker?" >:)

Living things use, store, and emit energies and other chemical compounds; non-living things don't.  Living organsims burn off 90% of all the energy that it intakes and only 10% turns into other muscle tissue or is stored for further usage.  So if a bird eats ten fish then only abou 1 of those fish's nutrients will make up the bird's mass and be stored the other 9 fish's nutrients will be burned in daily activities.  At least I'm pretty sure that's how it is.

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

Warm-blooded animals maintain thermal homeostasis; that is, they keep their core body temperature at a nearly constant level regardless of the temperature of the surrounding environment. This can involve not only the ability to generate heat, but also the ability to cool down. Warm-blooded animals control their body temperature by regulating their metabolic rates (e.g. increasing their metabolic rate as the surrounding temperature begins to decrease).\n\nBoth the terms "warm-blooded" and "cold-blooded" have fallen out of favor with scientists, because of the generality of the terms, and due to an increased understanding in this field. Body temperature types do not fall into simple either/or categories. Each term may be replaced with one or more variants (see: breaking down warm-bloodedness). Body temperature maintenance incorporates a wide range of different techniques that result in a body temperature continuum, with the traditional ideals of warm-blooded and cold-blooded being at opposite ends of the spectrum.\n\nBreaking down warm-bloodedness\nWarm-bloodedness generally refers to three separate aspects of thermoregulation.\n\nEndothermy is the ability of some creatures to control their body temperatures through internal means such as muscle shivering, fat burning, and panting (Greek: endo = "within," therm = "heat"). \nHomeothermy is the kind of thermoregulation used by those creatures that maintain a stable internal body temperature regardless of external influence. This temperature is often higher than the immediate environment (Greek: homoios = "same, identical," therm = "heat"). \nTachymetabolism is the kind of thermoregulation used by creatures that maintain a high resting metabolism (Greek: tachy = "fast, swift," metabol = "to change"). Tachymetabolic creatures are, essentially, "on" all the time. Though their resting metabolism is still many times slower than their active metabolism, the difference is often not as large as that seen in bradymetabolic creatures. Tachymetabolic creatures have a harder time dealing with a scarcity of food.

Elasmobranchs (sharks, skates, and rays) indeed have an interesting sensory physiology enabling them to sense a variety of physical stimuli.  But fear is not one of them. That said, it is true though that fear may be associated with either the release of particular chemical compounds, but far more importantly and likey in regards to your question, with particular behavior.  And in that sharks are not very different from any other predator.\n\nThe sense of smell is indeed very well established in almost all elasmobranchs; if you ever take a look at a shark's brain note the extremely large bulbi olfactorii, the areas of the brain where smell is first analyzed.  The sentivity of shark noses for blood is often emphasized, but you must not imagine sharks to be "swimming noses."  Rather, they rely on different senses for different environmental conditions, prey, etc. The priority assigned to either one of the possible sensory modes is largely dependent on the life-style of the animal.  Given that there are over 400 different species, there are a few variations.\n\nLike many other aquatic animals (e.g., teleosts, but also amphibians) sharks rely on their lateral line organ for detecting objects in greater distances.  The lateral line organ is a tiny canal running along the side of the animal underneath the skin.  it is open to the environment through a set of pores, through which the shark can sense pressure differences in the water, as they are being produced for example by a fish in distress.  This can of course be misunderstood as "smelling fear," when in fact it is more like "sensing the panicked movements of a potential prey."\n\nThe electromagnetic sense of elasmobranchs is perhaps most amazing from a human point of view, since it is so very different from anything we have.  All elasmobranchs have Ampullae of Lorentzi, with which the animals can indeed sense bioelectric fields.  These organs are so sensitive that a dogfish can sense the bioelectric field induced by the beating heart of a flounder covered by sand.  Sharks also use this organ for a magnetic compass.  By swimming through the earth's magnetic field, a shark will induce an electric current that will either run from its back to its belly (when the animal swims in an eastern direction), or from its belly to its back (in western direction).  with its own electromagnetic sensores, the animal can sense the induced electric current and its direction and can thus orient itself along the magnetic field of the earth.  Again, very sexy and very helpful, but no detector of fear!\n\nNow, some sharks use their eyes when they hunt prey, and this may an important point in regards to your question.  Great white sharks (Carcharodon carcharias) often attack their prey (e.g., seals) from far below, orienting themselves visually in their attack and going for the tell-tale silhoutte of the pinniped.  Some sharks, like the lemon shark (Negaprion brevirostris), have an interesting eye, where the sensitivity of the retina changes from light of one particular wavelength during day time to one of a different wavelength during night time.  This Purkinje-shift allows the animals to see optimally during day and night.  Now, many animals (or humans) in distress show a particular behavior.  Sometimes, a flight response is what is initiated when faced with a predator.  This behavior can signal the shark that the fleeing animal (or human) is afraid and therefore not a danger but rather a potential prey.  Consequently, fear in humans that cause a flight response may cause sharks to respond accordingly.  This may also be misunderstood as "smelling fear."  This, by the way, is the same kind of behavior a cougar, dog, or bear will dislay.\n\nThat said, there is always the possibility that during fear a human may release certain chemical compounds that the shark can smell.  But I doubt that this is something really significant in a real-life encounter.\n\n

No, they are not fish...the following was taken from Yahoo!\n\nhttp://ask.yahoo.com/ask/20030507.html\n\nTrue fish are vertebrates and belong to the Chordata phylum of the animal kingdom. This group encompasses most of the animals we are familiar with, such as mammals, birds, reptiles, and amphibians, as well as humans. \nStarfish, or sea stars as they are sometimes called, are invertebrates, meaning they have no backbone. These spineless (and we mean that in the best possible way) creatures belong to the spiny-skinned phylum of animals known as Echinodermata and the class Asteroidea.
