do tadpoles eat blood warms?
438212
There are a few species of tadpoles that can be carnivorous.  It would depend on what species you are talking about.\n\nThe vast majority of tadpoles eat algae and bacteria, and would not eat blood worms (which are actually fly larvae, some of the species in the Family Chironomidae).

They dont really eat anything as such. They have sensors sort of thing between the trap. When any foreign body, say bug, flies or even ur finger comes in it, it senses it and instantly the trap closes. then the nitrients from the body of the foreign body are extracted and used for the plant's nutrition.

some frogs can blend in with their surroundings. theyre green like leaves, some have brownish tones on their bodies to blend in with dirt and twigs, etc.\n\nalso some tree frogs are poisonous

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

Yes, vertebrates DO have circulatory systems.\n\nPutting a question mark on the end of a sentence fragment copied from your homework does not make it a comprehensible question.

Some fish are warm blooded such as tuna and the great white shark.\n\nHow Hot Tuna (and Some Sharks) Stay Warm\nScientists now have direct evidence that the north Pacific salmon shark maintains its red muscle (RM) at 68-86 degrees Fahrenheit (F), much warmer than the 47 F water in which it lives. The elevated muscle temperature presumably helps the salmon shark survive the cold waters of the north Pacific and take advantage of the abundant food supply there. The heat also appears to factor into the fish's impressive swimming ability.\n\n\nLamnid sharks maintain an elevated temperature in the red muscle concentrated in their mid-region near the backbone. This specialized anatomy allows the predators to swim fast and continuously, which in turn, allows heat to be retained in the core of the fish leading to local warm-bloodedness. In most other fish, the red muscle is located close to the skin, yielding a fully cold-blooded body and only short bursts of rapid, powerful swimming. (Credit: Zina Deretsky, National Science Foundation)\n\nDuring what some would say was a better-than-average day at work, Robert Shadwick of the Scripps Institution of Oceanography and his colleagues went salmon shark fishing in the Gulf of Alaska. After catching specimens over 7-feet long and weighing more than 300 pounds, the researchers measured temperatures throughout the sharks' bodies and tested the mechanical power of RM samples.\n\nTheir results, published in the Oct. 27 issue of the journal Nature, showed that at 50 F, RM produced only 25-50 percent of the power it produced at 79 F. The researchers concluded that RM temperatures below 68 F could permanently impair muscle function.\n\nNational Science Foundation (NSF) program manager, Ione Hunt von Herbing said, "Knowing specific details about the anatomy and physiology of salmon sharks provides key insight into their ability to produce such power and speed during swimming. The knowledge could translate into better designs for underwater vehicles."\n\nThe study was funded by NSF's integrative organismal biology program.\n\nSalmon sharks are lamnids, a group of sharks that also includes the mako and great white. Numerous studies have shown that lamnid sharks and tunas share many anatomical and physiological specializations that endow them with their impressive swimming power and speed. In contrast to other fish where the RM is near the skin, the RM of these sharks and tunas is near the backbone. Even though the ancestors of bony tuna and cartilaginous sharks diverged more than 400 million years ago, selection pressure for high-performance swimming in each group seems to have occurred independently about 50 million years ago.\n\nThroughout its life, a salmon shark never stops swimming because it will sink. The body heat generated from continuous swimming elevates the RM temperature, which in turn, warms the surrounding white muscle and allows the shark to survive the frigid waters of the north Pacific. If a shark stops swimming, it could die from cold exposure.

In most female mosquitoes, the mouth parts form a long proboscis for piercing the skin of mammals (or in some cases birds or even reptiles and amphibians) to suck their blood. As opposed to a syringe's typically smooth needle, the mosquito proboscis is highly serrated, which leaves a minimal number of points of contact with the skin being pierced — this reduces nerve stimulation to the point where the "bite" is not felt at all, which is generally the case .The females require protein for egg development, and since the normal mosquito diet consists of nectar and fruit juice, which has no protein, most must drink blood to get the necessary protein. Males differ from females, with mouth parts not suitable for blood sucking.

First we have to understand why leeches need blood to survive.  Blood is made up of rich proteins and lipids that allow a leech to live quite well.  Second, we need to understand the mechanism by which leeches are attracted to their "prey" Basically, all mammals (both warm and cold blooded) are privy to leech attachment.  It has been widely discussed that the exact attraction of leeches to a mammal involves secretion of pheromones and other biological chemicals that a leech's detectors will recognize.  Since other leeches don't secrete these biological chemicals, they are safe from "attack".

Well, you can answer that on several levels.  As several people mentioned they don't have sweat glands in their skin.  But, at risk of sounding like a four year old, why?!\nThink about why you sweat.  The water contained in the sweat sits on the suface of your skin.  Due to wind and solar heating, that water evaporates.  That evaporation takes energy - specifically, heat energy.  Removing that heat energy makes you cooler.\nIf a fish sweated, the sweat would just go into the surrounding water and not do anything to help the fish.\n\nAn even better question might be:  are most fish cold-blooded because their ancestors were, or because it simply isn't worth the energy to become warm-blooded if you live in a liquid?\n\nSee...ask a silly question...get a long-winded answer...

Amphibians as a group are not doing that well on the planet and are one of the most sensitive groups suffering losses during environemntal degradation of the planet, esp their larval stages.  But here are a few cool things about them:\n\ntoads estivate and bury themselves deep in mud with spades on their back feet during peak heat-dry periods of summer\n\nfrogs hibernate-freeze (they are ectotherms) and can stay at bottle of a pond-lake frozen and thaw out in spring thaws.\n\npoison glands on skin and slimey skin helps them have a chance against some predation.\n\ngreat camoflauge on some species skin, esp with dorsal side of frog being greenish and ventral underside being whitish so they blend in their environment. \n\nGreat bright colors on some frogs in rain forest is a warning of their degree of poisonous-ness.....warning to animals to stay away and not eat-touch them.

No they are not dangerous, they just freak the holy begebies out of most people.\n\nThey are not poisonous. They will bite if handled improperly (and it will hurt), just wash the bite with soap and warm water.  They eat plants.\n\nFollow link for description of them.

I'd never heard of grassfrogs, but I've done some reading about them.\nThis site:\nhttp://www.goldlinksweb.com/growlinggrassfrog/aboutfrog.html\nis a good resource for learning about them.  It doesn't say anything about tadpoles flying, but it does say that grassfrogs can travel over a long distance with no water.\nIt also says that the grassfrogs are rare, a protected species in Victoria, as a matter of fact.\n\nAnother site:\nhttp://www.studiocinqo.com/p_veenvliet/2_5_midwintertadpoles.htm\nmentions that though many grassfrogs hatched there aren't many tadpoles around.  He says that predators have eaten the tadpoles.  That might be your answer.\n\nHere's what another site said.  It again says that this is a threatened species.  \nThreats \nChytridiomycosis is an emerging infectious disease of frogs skin caused by the chytrid fungus, Batrachochytrium dendrobatidis and has been linked with continuing amphibian population declines in the western USA, Central America, Europe, Africa, and Australia. Ongoing studies suggest a correlation between resistance to lethal infection by B. dendrobatidis and synthesis (production) of antimicrobial peptides by the host amphibian. Further research is needed to define better the role of antimicrobial peptides in protection of amphibian populations and the effect of environmental factors upon antimicrobial peptide synthesis (Rollins-Smith & Conlon 2005). \n\nPhysical and environmental impacts include direct loss of habitat through removal of aquatic and riparian vegetation particularly by allowing grazing to the water edge. Draining of wetlands, lowing of freshwater groundwater through pumping and increased salinity from run-off and altered hydrological systems can all alter Growling Grass Frog habitat. \n\nPredator species such as the introduced Mosquito Fish Gambusia affinis can impact on tadpoles, Mosquito Fish are prolific breeders producing off spring three or four times per year. They can tolerate poor water quality and can inhabit waters otherwise unsuitable to many of the native freshwater fishes, which increases their capacity to prey on tadpoles. \n\nElevated nitrate and phosphate concentrations have been identified as a impact. Historical and experimental evidence suggests that in New South Wales the decline of Green and Golden Bell Frog L. aurea in its former range was due to high nutrient run off events. Fertilizers may also increase the nutrient status of waterbodies and thereby initiate eutrophication, resulting in lowered dissolved oxygen levels that do not support tadpoles (Hamer et al 2004). \n\n\nhttp://bird.net.au/bird/index.php?title=Growling_Grass_Frog\nCan the frogs be moved somehow?  Discouraged with sounds?  I don't really know the answer, but I hope these sites will help you.  You could also call the natural resources organization in your area. They might have some good ideas for you.

All animals prior to birds and mammals are cold-blooded, thus cold-bloodedness is the norm, not worm-bloodedness.  The greatest advantage is that, ounce for ounce, cold blooded animals need approximately 1/10th the amount of food.  Thus, during times of famine, when there is little food around, these animals can survive much better than mammals.  There is another advantage that isnt commonly discussed, and thats that cold-blooded animals can function at many different blood temperatures, while even a small change in blood temperature in mammals will cause severe loss of function.  One other advantage is that cold-blooded animals are nearly invisible to predators that can detect body heat, such as snakes.  Thus rattlesnakes, which are very sensitive to infrared, primarily prey on mice and other small animals, and only on other snakes or lizards when they are close enough to see clearly.  Also, in chilly conditions, above freezing, adapted cold-blooded animals can survive with very little loss of energy, while mammals and birds must expend *more* energy than normal to maintain heat.  Therefore, as long as the temperature doesnt drop below freezing, reptiles are actually at an advantage.  The advantages to being warm-blooded arent as powerful as we might think.  When Komodo island was discovered, and the large predatory lizards were a pest, Europeans brought in hundreds of hunting dogs and released them, quite sure that the dogs would clear the island of the evil lizards. When the Europeans came back years later, they found no dogs, and lots of fat and happy lizards....

Frogs come in variety of colors but the majority of them are green. Being green when sitting on green leaves has obvious advantages if you want to avoid becoming an easy meal for some hungry predator. \n\nFrogs are not green because they have green pigment in their skin.In their skins they have three types of pigment cells (called chromatophores) stacked on top of each other. At the bottom are melanophores, containing a mostly dark pigment called melanin. These are the same cells that can make human skin various shades of brown. On top of the melanophores are iridophores, packed with highly reflective bundles of purine crystals, and on top of the iridophores are xanthophores, usually packed with yellowish pteridine pigments. In the typical green frog, light penetrates to the iridophores, which act like tiny mirrors to reflect mostly blue light back into the xanthophores above them. These cells act like yellow filters, so the light escaping the skin surface appears green to our eyes.\n\nBy manipulating all three types of pigment cells, a wide range of colors can be produced, although usually the range extends from bright green to various shades of brown and gray. In frogs, all of these changes appear to be mediated by hormones circulating in the blood. The advantage of such color change is obvious. Imagine a frog leaping from a green leaf onto a brown tree branch. Melanin moves, reflective purine crystals shift position, yellow pteridine pigments cluster or disperse, and voila, that green frog that stood out like, well, like a green frog sitting on a brown branch is now a well camouflaged brown frog.

They'll eat pretty much any small vertebrate in the trees - lizards, frogs, birds and bats. Paradise Tree snakes are primarily lizard eaters.
