Do Frogs have toe nails?

Not usually. Tree frogs do but many don't. There are so many varieties of frogs that you can't really make a generalization about all of them except maybe that they're amphibians.

frogs like to swim in the water and are more aquatic than terrestrial, but they have very well developed meaty leg muscles, (both the calf and the thighs) and many muscles the same as humans which they can use for hopping too. They just use their hind legs for hopping though.  Those puny little arms-hands-muscles are not used for much other than propping themselves up when sitting, or a male may squeeze a female when he is on her back mating with her.

i dont know if this is true..but i heard once when i was a kid that tadpoles draw the nutrients they need from theyre little tails. i heard that its the same concept as little creatures eating their shells after breaking out of them. This might be urban legend but it makes sense to me! what else happens to their little tails? and please..nobody correct me or i will feel really really stupid for believing this if its not true

The spotted frogs have declined sharply. They don't know how to avoid fish and bullfrogs. They didn't evolve in an environment where they had to avoid them.\n\nhttp://www.oregonlive.com/news/oregonian/index.ssf?/news/oregonian/00/07/nw_51spot27.frame

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?" >:)

Sorta.\n\nSome turtles are known to practice 'cloacal breathing'- absorbing oxygen through air in the cloaca- the single opening used for excretion, urination, and reproduction. This is documented in the Fitzroy River turtle (Rheodytes leukops) and may occur in others.\n\nHOWEVER- to be accurate...\na.) turtles don't have 'butts' in the sense of two large masses of muscle and tissue surrounding the anus.\nb.) even if we call that area a 'butt', turtles do not breathe through the skin and muscle there. Mammals do not excrete through their 'butts', they do it through the anus- a different body part!

I know it will take forever but if you get one of those black or grey emery boards--not the steel ones--you can file your toe nails.  Clipping them and filing them will help them to grow slower.  Also to me, the best way to clip my toe nails is to shower first and then immediately clip them afterwards.  The warm water from the shower loosens the nails making them more flexible and easier to cut.  That way you won't clip your tissue.

1. amphibians don't have AMNIOTE land egg. Reptiles do.Thus amphibians lay LOTS of eggs which have HIGH mortality rates from fungus, other organisms eating them; reptiles eggs are less vulnerable to mortality and so they lay fewer and have higher rate of hatching\n2. amphibians mate with external fertilization. Reptiles have internal fertilization and mate with HEMIPENES, not penis (true penis is in mammals!)\n3. slimy skin in amphibians, so they need water env, vs reptiles have heat-dessication resistant scales\n4. Most nitrogenous wastes of amphibians are ammonia\nreptiles have very concentrated uric acid\n5. amphibians and most reptiles have 3 chambered heart, but CROCODILIANS have a partial septum in their ventricle\n6. metamorphosis in amphibians, dev in egg in reptiles\n7. reptilian skull much more solid-heavy than amphibians.  There are more bones in reptiles (radio-ulna is ONE bone in frog, tibio-fibula is ONE bone in frog.  Reptiles have the same lower leg-arm bones as us humans and are NOT fused as in amphibians. Amphibians lack ribs, reptiles with ribs.\n8. ear HOLE and external ear on reptile head. Amphibians just have the tympanic membrane there,so they don't have much of an external ear.

How many toes do you have?

There is a family of frogs, the Pipidae (the Surinam frog genus Pipa, and the African clawed frog genus Xenopus) that lack a tongue. They are entirely aquatic and Xenopus is often sold as an aquarium pet.

You have more stimulation in your fingers than your toes.\n\nYou are constantly bending or moving your fingers. This stimulates them and makes your nails grow faster.\n\nYes you do walk on your toes but you are not constantly moving them to create as much stimulation.

A human finger, or was it a toe

Yes, they do.  They eat frogs, clams, mice, rabbits, white grubs and beetles.

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!

Toads and frogs are BOTH amphibians.  Frogs have more permeable skin so lose more water through their skin and need a wetter environment.  Toads have dryer, wartier skin and are generally darker in color. Frogs lay eggs in clusters on water, toads lay eggs in strings. Frogs jump farther and have longer legs, toads hop. Frogs have tiny teeth, toads do not have teeth.
