It depends on the shark as many sharks lay eggs or keep eggs within them until they hatch. There are other sharks who use a placenta. The spiny dogfish shark has the longest gestation period of 22 months with gestation periods lasting at least a year. Shark pups are fully self-sufficient and quickly move away from their mother who may eat them.

I have found reliable citations at Fishbase of 29 years, and others cite 17-15 years (for the species Chimaera monstrosa). This is not unexpected, given that these fishes, like all chondrichthyans, grow relatively slowly and take several years to become sexually mature. These are very long-lived animals.\n\nhttp://www.fishbase.org/PopDyn/PopCharList.php?ID=2503&GenusName=Chimaera&SpeciesName=monstrosa&fc=25

Great White Shark - The average length is about 4.3 – 4.6m (14–15ft), females generally being larger than males... Some do reaching lengths of about 6 meters (20 feet)...\n\nHope this can help U... If need more information on Great White Shark feel free to contact me...Will try to answer all your question..\n\nAnd U can check the following website for the size of the Great White Shark...

It depends on the breed of penguin. The emperor penguin has a 63 day gestation period.

The mating season, lasting from September to October, is followed by a nine-month gestation period after which 600- 700 eggs are laid and wrapped in a silky cocoon which the female, alone, guards aggressively. The mother tolerates the babies for a short period of time in which she might even feed them regurgitated food, but very briefly. Within a matter of weeks, or certainly by the time the female has her next molt, the babies are on their own. The mortality rate is very high and ants are a major menace. The life span of the female is thought to be 15- 25 years and possibly more than that. The male lives a much shorter time, not only because the female sometimes eats him, but more frequently because he does not molt correctly, or cannot escape his molt for some reason. Also, the male is usually the one seeking to mate, and so is more exposed to predictors.

If you start your period while out in the ocean do make sure there are people shark spotting. There shouldn't be too much of a problem if you are using a tampon but you should make sure you are not in the water early morning or at dusk. These are regular shark hunting times.  If you can get a wetsuit, that would be the best idea. It's not all that saucy but it's better to be safe then sorry. I do hope you have a great time!

Courtship, mating and reproduction : Like all snakes and lizards, male sea snakes have two penises. They are called hemipenes, but each is an autonomous independently functioning penis and only one is used during mating. Mating takes place for long periods and sea snakes must surface for air during that time. The female controls breathing and as she swims to the surface the male is pulled along attached via the hemipenis. At the surface the male needs to gulp for air or he has to wait til the next time the female comes up the the surface to breathe. Males are unable to disengage until mating is finished. \n\nIn species where courtship has been studied, eg olive and turtlehead sea snakes, one or more males follow the female very closely and occasionally prod the head and neck of females. \n\nAll sea snakes except the latidcaudids give birth to live young after gestation periods that range from four to eleven months, depending on the species. Most species reproduce every year. The timing of the reproductive cycle varies enomously between species and also differs between geographical locations for the same species. \n\nYoung are born underwater and must be independent immediately to swim to the surface to breathe. There is no parental care. In some species look quite different to the adults eg juvenile olive sea snake are strongly banded while the adults are not.

At three weeks, you won't really see a whole lot of growth visable to the naked eye.  Depending on various factors, like how well you feed him, the condition of his tank water, heat, UVA/UVB lighting, etc, it could take anywhere from 5 to 15 years for him to reach his adult size.  I would say if a few months have gone by, and you're taking care of him properly, if you're still concerned about his growth rate, take him to a reputable herp vet.  Otherwise, I wouldn't worry too much.  Just like human children, some grow slower than others, and some get to be larger than others.  Remember, also, that if you do have a male, he's not going to grow as large as a female would.

A fully grown great white shark of 18 feet or more in length weighing a ton or even two ton has nothing to fear from anything in the ocean. However, a subadult great white of only ten feet or less and less than 800 pounds is food for giant squid and killer whales. The giant squid would have to be fully grown to do this. It is believed by scientist to reach 60 feet in length and weigh one ton.

the tapeworm doesnt really have a gestation period. it just releases a segment of itself filled with eggs. then pass through the animals systemand are later consumed by other animals.also found this sight on squids it might help

On average, about two weeks.\n\nHowever, the best way to tell (and even this is not 100% reliable) is to take your basal body temperature every day.  At ovulation, the basal body temperature will increase by a degree or so (celsius).  It will stay elevated until you menstruate again.\n\nThat's the basis of the "rhythm method" or "natural family planning" or whatever else you want to call it.\n\nCheers!
