how does the spiky-skinned armadillo lizard of South Africa protect itself?
480336
With a tazer.  Or possibly with its spiky skin?

It may be a Sagebush lizard or a Western fence lizard. Would have helped if I know which state you were from.

Snakes, lizards and amphisbaena (which most of you won't have heard of, but they're neat!) have "hemipenes", basically dual penises.  It has no real advantage, it's just how they evolved.  They only use one at a time.  It's just a different way to evolve a penis structure on a bilaterally symmetrical animal.

Simple  my friend:\n\nZebras do not have pockets and therefore if they were to mug lions they would have no-where to put anything they mugged off them.\nThats the trouble with zebras everything is so black and white.\nNow Kangeroos, they will mug anything as they have the storage capacity and also know where they can get rid of the goods\n\nMany a dingo has lost jewelry cash and mobiles to a rampaging bunch of roos\n\nIn Africa the lion very rarely gets mugged and if he did he wouldnt tell anyone about it because of his pride\n\nPride is important to a lion, i know that because david attenborough said it once on planet earth..well lets be honest he isnt going to say it on the moon is he\nHope this helps

a lizard and a snake. neither harms the other or benefits. they live together in peace and harmony.

Read up on any particular reptiles you have.  Keep all your reptiles hydrated.  Ultraviolet radiation ie: sunlight, ultraviolet lamps is key to keeping your reptiles healthy.  They require this to help them digest their food.  Herbavores require a varied diet, not just lettuce!!!!

If you're talking about what I think you are, then it is not dangerous at all. It can spray a nasty vineger stuff to scare off predators, which would hurt if you get it in your eyes. But the only thing that really needs to be afraid of that is a cricket.\n\n\nHeh, sorry, wrong picture. I was in a hurry to get to school. So yeah, it sprays from a gland at the base of the tail. It's called a vinegarone, or sometimes a whipscorpions. Whipscorpion can sometimes give you the wrong thing though, like the picture I gave earlier. Try the other link or look up some more.

DESCRIPTION: \n\nThis unusual mid-sized stocky agamid lizard has prominent spines along its sides and a large, essentially triangle-shaped head. Forming a sort of shield around the snout is a spiney jaw pouch which, when swollen, looks like a beard and makes any predator think twice before attacking. This wide-ranging species shows considerable geographic variation; its basic color varies from shades of brown, gray, and reddish-brown to bright orange. The ventral surface ranges from pale to dark gray, with white elongated spots edged with black. Mature males have dark "beards" which become black during courtship and breeding. Adults can grow as large as ten inches in body length or two feet in total length, including the tail. Males are larger than females. \n\nII. GEOGRAPHICAL RANGE AND HABITAT: \n\nThese lizards are native to Central Australia. They prefer semi-arid to arid woodland habitats. Time is spent both on the ground and in trees. They may be found perched on bush branches and even on fence posts. \n\nIII. DIET:\n\nBearded dragons are omnivorous and consume many types of insects, small vertebrates, and vegetation including fruits and flowers. \n\nIV. LIFE CYCLE/SOCIAL STRUCTURE:\n\nSexual maturity is reached at one to two years of age. Mature females typically lay clutches of eleven to sixteen oblong leathery eggs in early summer. The eggs are laid in nests dug in sandy soil and the unattended young hatch 3 months later. \n\nV. SPECIAL ADAPTATIONS:\n\nA bulky body and the habit of basking allows them to store heat, making it possible to operate at lower temperatures than other lizards. They can also survive higher temperatures for several hours, since they can regulate body temperature by evaporation. \n\nVI. INTERPRETIVE INFORMATION:\n\nWhen intimidated, they flatten their bodies and stand erect with mouth gaping. The light-colored mouth lining, spines bordering the lower jaw and puffed-out blackish beard give a formidable appearance. This defensive display has earned these lizards the common name of "bearded dragon". \nAggressiveness to other members of the group is shown through "body language". The tip of the tail is slightly curved at the end and the head is bobbed rapidly. Submission is signaled by rotating the arms in a full circular motion, which looks a bit like waving. Ritualistic sparring matches take place in which both animals are in flat postures, beards and tails up and outward; they circle each other, biting at one another's tail, but usually no damage is done. \n\nTheir ability to change shades of color, from light to dark, helps them to regulate body temperature. Color changes can also depend on emotional state, and may also be used for concealment. When injured, sick, or dying the back becomes black and the legs pale yellow. \n\nAustralian desert lizards often make their escape by rising on their hind legs and running bipedally. They cannot run as fast as when using four feet, but perhaps this behavior aids in temperature control. They lift their bodies from the hot ground to lose the heat they generate in running. This reduces the amount of heat they take in from the ground and increases the cooling airflow over their bodies.

If you consider evolution, any animal that is able to protect itself will. They would have only adapted the ability to fight off enemies or hide from them if it was something that they used and it saved their lives. The only "passive" animals out there are the ones who don't have the ability to defend themselves. So to answer your question, no, there are no animals who naturally choose to not protect themselves when they are capable. Only on an individual basis could this happen. There are no known species or populations that do that.\n\nThe sloth is endangered because we cut down its trees that keep it safe. Frogs don't let animals eat them, they try to run away. The closest thing to what you are describing that I can think of would be a mother duck pretending to be injured to lure the predator away from the chicks. Of course, when she gets it away from the chicks, she too flies away.

Notostracans (often just called Triops, tadpole shrimp or shield shrimp) are small crustaceans in the Branchiopoda group. Triops have internal compound eyes and a flattened shield covering the head and leg-bearing segments of the body. The order contains a single family, with only two extant genera. Their external morphology has not changed since the Triassic (appearance of Triops cancriformis around 220 million years ago). Triops cancriformis may therefore be the "oldest living animal species on earth" (Kelber, 1999).\n\nTadpole shrimps usually live near the ground of astatic pools, where they move with their ventral side down. However, lack of oxygen can force them to swim upside-down with their gill-like legs close under the surface of the water. Notostraca are omnivorous; they dig around in the mud using the frontal part of their shield, looking not only for plankton but also for larger prey such as worms, chironomid larvae and even weak tadpoles. Anostracans, often associated with notostracans, can also be a considerable part of their prey (especially when weak or dying).\n\nNotostracans sometimes even cannibalize freshly moulted members of the same species. In northern and central Europe, with few exceptions, all tadpole shrimps are female, whereas sex ratios in southern and western Europe as well as in northern Africa are near unity. These "females" possess hermaphroditic glands, but instead of selfing, parthenogenesis takes place. Modified appendages of the 11th pair of limbs bear the ovisacs with the mature eggs.\n\nTriops evolved to survive in naturally temporary ponds all over the world. As inhabitants of such, there has never been any pressure for them to become long-lived creatures. These ponds usually dry up during certain times of the year when there is no rainfall. Although the adult Triops die during these droughts, the embryos remain in a state of diapause (suspended animation) until the rains return and fill up the temporary ponds once again, making it safe for them to hatch.\n\nThe maximum life spans in the lab agree with data from field observations on Triops survival. In the lab, T. longicaudatus has a maximum lifespan of about 50 days and T. cancriformis a maximum lifespan of about 90 days, with some individuals beginning to die off as soon as 2 weeks after hatching. Secondarily, some may suffer premature deaths from moulting complications or other reasons.

Try adding some cage furniture like a hollow log. Snakes and other reptile like a lot of hiding spots to make them feel secure. The enclosure also can be too small, I recommend no less than a 20g tank.

Most male red-headed rock agama lizards are brown speckled, very similar to the females of the species. Only the dominant male of a group (these lizards live groups of 10-20) gains the striking blue blody and red/orange head for which the species is named. \n\nAs to the biological basis of this, agamas have specialized cells imbedded in their outer skin that allow them to change color. In chameleons, these cells may be activated as a result of the animal's physical or psychological state, or in response to the environment (to blend in). In agamas, the cells respond only to the lizard's psychological state, and in the case of the dominant male, this is one of aggression and control. \n\nWere another male in the group to develop similar coloration in response to a change in its psychological state, a fight would immediately ensue, leaving once again only one male with the distinct coloration in the group.

The basilisk lizard (also called the Jesus Christ lizard) has the ability to walk on water.\nMore info: http://en.wikipedia.org/wiki/Basiliscus_basiliscus

wow, those are some immature answers. Zebras have stripes for defense tactics. When they huddle together or move together, it is hard for a predator to single out one.

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

They tend to be an agressive snake.  They do not make good pets (Yes, there are some that remain small enough to be pets).\n\nOther than that, don't know what you're looking for...

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
