Its an axolotl, with an "a".

the first 1 would be frogs and the 2nd one would be lizards.....simple!!\nP.S.:thanks for the 2 points!

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.

There are some 5,000 species of frogs and toads, so you'll have to be a bit more specific about which one you need the name for.

They have mouth openings often with flagellum to help with their filter feeding.  The tail end is thinner and is lighter in color/more transparent.  Just do an image search for amphioxus and see!

Question is a little vague......anatomy is structural and function is physiological, so I am not sure what your question really is; is it about anatomy or physiology or both? So RSVP:  Are you asking about the unique physiology or anatomy of amphibians?\n\nThey have many structures in common with the other tetrapod vertebrates, but also have unique structures as amphibians.  Plus each sub-class-type of amphibian (frogs-toads) vs (newts-salamanders) vs caecilians are each different.\n\nAll amphibians have their unique slimey scaleless skin through which they attain most of their oxygen and release their CO2 by diffusion, their 3-chambered heart with 2 atria and 1 ventricle, their external fertilization type reproductive system that has egg-larva-tadpole and adult.  Their respiratory system changes at each stage of development. As tadpoles they use their gills. As they metamorphose to adults,the gills are absorbed and lungs develop to breathe air although they lack a diaphragm and ribs (in most...some amphibians retain larval stage for their whole life...axolotyl). They have kidneys and bladder for excretory system; endoskeleton is bone and has most of the same bones as us, although some are fused (radio-ulna, fibulo-tibia; no skull protecting brain, unusual urostyle bone of pelvis.

Toads, (like frogs, newts & other amhibians) deposit their eggs in the water as what is often called "frogspawn". It looks a litle like see-thru tapioca pudding, or sometimes like a string of tapioca. The fertilized eggs develop into 'polywogs' ot 'tadpoles', which look like little toads with tails.  Then they get bigger, and come out of the water.\n\nToads are bitter tasting and do not make good snacks. (My dog tells me this, quite often, by his expression upon biting into one, and the fact he always leaves half of each toad he tries!)

I have 2. My favorite is my Darwin fish/amphibian symbol.

Fishes, as all other vertebrates, have closed circulatory systems; they have a single blood circuit in which the heart pumps the blood toward the gills where it picks up oxygen, and is then distributed to the body. However, our (human) anatomy is very derived with respect to aquatic pisciform vertebrates. In fishes the circulatory system is very symmetrical and more metameric. The best place to look is the gill area, where the major vessels occur. The heart, which looks like an elongated bulb, is situated ventrally right behind the gill basket. The ventral aorta is the major vessel extending forward below the gills, and emits branches to each functional gill. Once they go through the gill filaments, these vessels reunite dorsally and form the dorsal aorta (paired, then joined). Other vessels are difficult to observe as they usually collapse in dead materials, but if you have fresh large specimens you could try injecting a colored rubber solution (VERY carefully) inside the largest vessel you can find and if the walls are not broken, you will get an internal cast of part of the system. \nAlso look for the dorsal longitudinal vessels that are really close to the vertebrae, passing through the haemal arches.

Water dog is one of the common names given to any of a variety of different kinds of salamanders and newts. \n\nIt most commonly refers to the genus Necturus, also known as mud puppies.\n\nThey do have remarkable powers of regeneration, often (but not always) able to regrow legs, or a tail.  However, if you cut off their head, they're very much dead afterwards.

Not sure but it ISN"T snakes and frogs. We have plenty here! Possibly a newt.

The modern amphibians (a natural group called Lissamphibia) comprise urodeles (salamanders), anures (frogs and toads) and caecilians or apodes. These are intriguing amphibians because they're highly adapted to life underground or in water, and few people know them or have ever seen them in the wild, although they're fairly common in all the world. \nThe name "caecilia" means "blind", and indeed their eyes are covered by the skin and sometimes by bone too, although they can perceive light and dark. \nI like them, if only because I share my first name with them. \nHere's a picture of one showing their exclusive sensory tentacle:\nhttp://www4.nau.edu/bilby/photo_illustration_page/images_photo_page/Caecilian.jpg

Rupali there are multitude of animals having gills to respire.Gills as a respiratory organs-Arthropods-Prawns,Shrimp,Mosquito at larval stage. All amphibians and Fish -some stage of life.All mammals on some stage of life.As in humans embryo.Practically all animals have gills as respiratory organs from non chordates Arthropod to Mammals.
