are box turtles amphibians or reptiles?

Reptiles, although living "reptiles" are not a natural group. \nAmphibians have naked permeable skin and usually depend on aquatic environments for reproduction. Turtles, as amniotes, have keratinized skin (with scales) and lay terrestrial eggs.

Modern cladistic methods have eliminated the idea of "classes" as distinct taxonomic categories that are in the same level with each other, so there aren't 7 "classes" of vertebrates. \nIn a traditional sense, these could be: agnathans (jawless vertebrates: hagfish and lampreys), chondrichthyans (cartilaginous fishes), osteichthyans (bony fishes), amphibians (frogs, toads, newts, etc), reptiles (snakes, lizards, crocodiles, turtles), birds and mammals.\nBut I repeat: this type of classification scheme does NOT reflect the current evolutionary/phylogenetic hypotheses and is not used anymore. For example, the bony fishes include the tetrapods (amphibians, reptiles, birds and mammals). "Reptiles" is not a natural group, as birds are more closely allied to crocodiles.

Most amphibians eat insects, however their are alos species that prey primarily on fish, crustations and even mammals. \n\nCrocodiles are NOT amphibians. Thay are amphibious which is quite a different thing.

THE MAIN DIFFERENCE IS THAT AMPHIBIANS ARE DEPENDANT ON WATER. So obviously, adaptation will be based on this difference...\n\nMost reptiles are not as dependent upon nearby water as amphibians. Reptiles have solved the drying-out process by having the skin covered with hard, overlapping scales which help to keep moisture from excaping the body. Reptile eggs do not need to be laid in water because, unlike amphibain eggs, they have a tough shell which helps conserve moisture. Some reptiles may even retain eggs inside the body until they hatch, then giving birth to live young.\n\nreptiles have claws on their feet to help climb, run and dig on land. Because most reptiles are not dependent upon a body of water for reproduction, they can live in places such as deserts where it would difficult for amphibians to survive. Some reptiles, such as crocodilians, many turtles, some snakes and a few lizards have gone back to living in the water, but they breathe air through their lungs and must still emerge from the water to lay their eggs on land

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.

Tavastone -vs- Tortius\nTortius is a mutant turtle who can slow down time to the point he is the fastest being in the world, able to do whatever he wants. Ruling the world. The only one who Might stop him Is Tavastone. Able to blend in, read his mind and anticipate when to freeze Tortius.\n- just wish I knew how it will end. Interesting.

Well,\nReptiles have scales. Amphibians have smooth skin (although some are warty). \nReptiles are total land animals. Amphibians need the water. And yet this is not always true. There are many marine reptiles, but they must go ashore to lay their eggs, well the sea snake might be a possible exception there. There are also amphibians that are able to spend their whole lives out of the water. They are rare, but there. \nThe real big difference (other than scales) is that reptiles use hardshelled, amniotic eggs for their babies. All amphibians have soft jellylike eggs. \n\nThere are several anatomical (pertaining to body structure) and reproductive differences between reptiles and amphibians. Reptiles include alligators, crocodiles, turtles, and snakes. Amphibians include salamanders, toads, and frogs.\n\nOne difference between the two is the structure of their outer skin. Reptiles are covered with scales, shields, or plates, and their toes have claws. Amphibians, on the other hand, have moist, glandular skins, and their toes lack claws.\n\nThe eggs of reptiles have a thick, hard shell that protects the developing embryo from moisture loss, even on dry land. In contrast, the eggs of amphibians lack a hard outer covering and, thus, must be laid in water or in damp places.\n\nFinally, young reptiles are miniature replicas of their parents in general appearance, although not always in coloration and pattern....\n\nReptiles and amphibians, along with birds, fish, and mammals, belong to a group of animals known as vertebrates. Vertebrates have a bony backbone–a strong, flexible column to which other body structures are attached. Reptiles and amphibians vary enormously in size, from tiny frogs and lizards only half an inch (1cm) long to some crocodiles and snakes that can reach lengths of nearly 30 feet

Temporal Fenestrae\n\nThese holes have to do w/ attachment of temporal muscles in the head. The ones responsible for pulling the jaw shut. I believe it also has something to do w/ jaw strength but I am not completely sure on that part.\n\nAnapsids didn't have the t.f. Turtles are the only living anapsids.\n\nSynapsids have one tf at the back of the head. This covers all the mammal-like reptiles. Precursors to mammals.\n\nEuryapsids also had one tf located high on the skull. Marine reptiles/plesiosaurs/etc.\n\nDiapsids had two tf. This category covers lizards, snakes, crocodiles, dinosaurs, birds, etc.\n\nWhile there was a function for these "holes" paleontologists use them more or less to help classify reptiles into categories.

Why are Reptiles there....If Birds Evolved from them?

Hylonomus lyelli and Paleothyris are the oldest-known true egg-laying reptiles. Their fossils have been found in 310,000,000-year-old coal deposits in Joggins, Nova Scotia. They were about 8 inches long in adulthood and looked like modern lizards. \n\nI couldn't pick them out of a lizard lineup, personally.

More than likely because their evolutionary record makes them the sole ancestors of birds, mammals, and modern reptiles. This makes the evolutionary classification of these animals hard: should we put mammals in the reptile clade? what about birds (actually, we already have agreed that birds are reptiles; nonetheless, there were huge debates before they were put in the reptile clade)? Really, the whole matter is a big headache.

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

We can't really prove it. All their insides were decayed, so the only evidence of them being reptiles is their bone structure. But for all we know, they could have been fuzzy, warm blooded, dinosaurs. There is no way to determine either way scientifically, because we can't see a live one.

Funny you should ask that as my pet frog had a fight with my neighbours turtle in 1986, soon after I moved there.\n\nMy frog is called Frank, the neighbours turtle is Tutle.\n\nWe buried them both 6 weeks ago, the vet said it was boredom.\n\nNo shit.

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.

The egg.  Reptiles were around a lot longer than chickens, and reptiles lay eggs.
