Water turtle  eggs usually hatch in 60-140 days (average 80-110 days) Eggs can be incubated by burying them in 1-2 inches of sand or dirt kept at 70-85 F.♥

If you're trying to get pregnant...  Those spermies should be swimming way up throught your cervix to your uterus to find that egg.  Normal bathing wouldn't send water up that far.  I'd say bath as soon as you feel inclined to.

Most of the time it's during the spring, but the reason is solely based on water temperature.  If you have an exceptionally cold early spring, they won't start spawning until late spring.  Once the water temperature gets in the high 50's to low 60's they'll start moving up and shortly thereafter, the spawning period will begin.

for short: egg-embryo-tadpole-froglet-frog.\n\nthey start breathing air as soon as they hatched from eggs. the tadpoles breathe with external gills, like salamanders. when they changed into froglet, the gills will start to disappear because at the same time, their external lungs will be developed enough to help them breathe.

What kind of turtle?What kind of weather is it in?But after the turtle hatches i give you good luck i love turtles they are so cute and fun loving

The eggs were already in the product. The eggs lie dormant until the environment is right, and then they hatch.

when air is compressed, it heats up. this could be circulated within the incubator to warm the eggs.

The male sea horse has a pouch in to which the female lays her eggs. The male fertilizes the eggs and cares for them for 3 weeks he also nourishes the eggs through a capillary network with is own placental fluids,that why the male sea horse carry the young ones.

salt water is heavier than fresh water. If the water is salty enough, the egg will float. Otherwise, it will sink.

It depends on the region of the country.  In Pennsylvania, turtles dig down into the ground and try to reach the frost line, which is about 42 inches.  Some don't make it that far.  Some turtle have been found at about 3 feet in the ground.  Some have been found closer to the surface. An early spring thaw and then a quick freezing may kill some turtles who come to the surface too soon. Rattlesnakes in our area hibernate in a den which is usually in rocky area or a side of a small mountain.  The dens vary in depth and some can be rather deep.  The snakes usually bunch up to conserve heat.\nHope this helps.  I live near a stream and every fall I find many turtles, such as box and wood, heading towards the stream area in September.  I recently have found some Nice specimens on my last walk by the stream.  They are tough creatures and nature is constantly amazing to observe.

Actually during seasonal changes there can be a colour change or spots appearing on turtles. I hope it may be a freshwater turtle. First make sure that it is a an infection. If so it may be bacterial or fungal. If the warty skin is turning to lesion/ or a fine tuft of hairy structures/ ooze from these/ loss of appetite/ lethargic/ or any disease symptom is there then we  can  confirm it is an infection. Unlike the land reptiles turtles have soft covering on its body. It can be considered equivalent to fishes. So the same treatment is applicable. Washing with potassium permanganate water, malachite green or metheline blue bath treatment or dip treatment is also effective. Tetracycline compounds 250 mg. one tablet in 20 l of water keep the animal for 1hr is also found effective. Above all hygiene is the most essential thing. Clean the tank and disinfect the tank in all the possible ways. Refill water with little potassium permanganate 2-3 crystals only. Your turtle will b alright.

i would imagine a scientist would do tests that show that a turtle is alert and able to respond, such as:\n\nvisual stimuli - put something near the turtle where it can see it - does it respond to the appearance of this item?\naural stimuli - make a noise that the turtle can hear - does it respond  to hearing that noise?\nscent stimuli - introduce a smell that the turtle can detect - does it respond?\ntactile stimuli - if you touch the turtle, does it respond?\ntemperature stimuli - if you put something hot or cold next to it, does it respond?\n\nthere are probably standard tests based on one or more of those types - and different times associated with level of alertness. clearly a sleeping turtle might not be very alert of something placed next to it.

Well they leave their eggs in the month of June to September\n\nFrom June to September, Puerto Vallarta is a breeding ground for sea turtles and the hotels and government sponsor conservation programs to protect their tiny charges. Vacationers can share in the wonder of life from June to September by participating in the hotel programs to protect the turtle hatchlings in their dash to the sea. Under a starry sky, children and adults release the baby turtles from buckets and applaud as the hatchlings scurry across the sand and plunge into the ocean

Perhaps, the time of birthing and mating is in the spring.  They can not lay their eggs on land.  So, if they do not have water to deposit them in, then new frogs can not be born.  Hence, the population declines.  What do you think?

Structure of the Amniotic Egg\nEvolution of eggs with a water-impermeable amniotic membrane surrounding a fluid-filled amniotic cavity permits embryonic development on land without danger of dessication. The main diagram shows the arrangement of membranes in a typical egg-laying oviparous vertebrates. In live-bearing viviparous vertebrates, the shell and chorionic membrane are absent and the allantoic and yolk sac membranes are incorporated into the connection with the maternal circulation\n( http://www.mun.ca/biology/scarr/Amniotic_egg.htm )\n\nThe amniotes are a microphylum of tetrapod vertebrates that include the Synapsida (mammals) and Reptilia (reptiles and dinosaurs, including birds). They are defined by embryonic development that includes the formation of several extensive membranes, the amnion, chorion, and allantois. Amniotes develop directly into a (typically) terrestrial form with limbs and a thick stratified epithelium, rather than first entering a feeding larval tadpole stage followed by metamorphosis as in amphibians. In amniotes the transition from a two-layered periderm to cornified epithelium is triggered by thyroid hormone during embryonic development, rather than metamorphosis [1]. The unique embryonic features of amniotes may reflect specializations of eggs to survive drier environments, or the massive size and yolk content of eggs designed for direct development to a larger size.\n\nFeatures of amniotes designed for survival on land include a sturdy but porous leathery or hard eggshell, and an allantois designed to facilitate respiration while providing a reservoir for disposal of wastes. Their kidneys and large intestines are also designed to retain water. Most mammals do not lay eggs, but corresponding structures may be found inside the placenta.\n\nThe first amniotes looked like small lizards, for instance Casineria kiddi who lived for about 340 million years ago, and their eggs were small and covered with a membrane, not a hard shell like often seen today. Some modern amphibians lay eggs on land but without any protection to speak of, while others like some lungless salamanders and Amphiuma also lay small eggs on land, but these are covered by a rubber-like membrane even if they lack advanced traits like an amnion. This kind of eggs became possible with internal fertilisation. The outer membrane, a soft shell, evolved as a protection against the harsher environments on land. It was probably because the embryos were safer on land than in water that some species got the habit of laying them out of the water. One can assume the ancestors of the amniotes laid their eggs in moist places, as such animals wouldn't have too many difficulties in finding depressions under fallen logs or other suitable places in the ancient forests, and dry conditions were probably not the main reason why the soft shell emerged.\n\nIn fish and amphibians there is only one inner membrane, also called an embryonic membrane. In amniotes the inner anatomy of the egg has evolved further, new structures have developed to take care of the gas exchanges between the embryo and the atmosphere, as well as dealing with the waste problems. To grow a thicker and thougher shell there were no other alternatives than finding new ways to supply the embryo with oxygen, as diffusion alone wouldn't be enough any more. After the egg had gotten these structures, further sophistication of them allowed the amniotes to lay much bigger eggs in much drier habitats. Bigger eggs meant bigger offspring, and bigger adults meant bigger eggs, which meant the amniotes had gotten the opportunity to grow bigger than their ancestors. But real growth was not possible until they stopped relying on small invertebrates as their main food source, and started to eat plants or other vertebrates, or returned to the water. New habits and heavier bodies meant further evolution for the amniotes, both in behavior and anatomy.\n\nThere are three main lines of amniotes, wh

Probably externally, like lots of other fishes.  They male releases the sperm, and the female releases the egg.  The sperm drifts towards the egg, and then the egg is fertilized.

Eggs, whether fertilized or unfertilized have largely the same consistency when they leave the hen.  If a fertilized egg is incubated (kept warm), then a chicken fetus will develop, resulting in a chick in about 21 days.\n\nFarmers who raise chickens for egg production (commercially sold eggs) are required in some states by law to "candle" all of their eggs before they are allowed to be sold.  Eggs are "candled" by being placed in front of a bright light.  An inspector then looks for any dark masses inside the egg, which could be a developing chicken (or bacterial growth).  The chances of a fertilized egg are relatively low since many chicken egg farms do not have any roosters in the cages with the hens.  Even if a fertilized egg somehow did make it through, the prompt  collection and refrigeration of eggs would stop any further development.
