King Cobras Gestation Period

In the story “Rikki-tikki-tavi” by Rudyard Kipling, two evil cobras, Nag and Nagaina, want to kill the family that lives in the house next to their garden. A little mongoose named Rikki-tikki-tavi (Rikki) gets washed up into a bungalow garden by a flood. A little boy named Teddy finds him in the garden with his mother and they keep him. They feed him, and take care of him like their on child. One day while in the garden Rikki meets Darzee, while they are talking Nag and Nagaina tried to sneak up and kill Rikki, he would have died if Darzee’s wife hadn’t warned him. Another time a little brown snake, Karait, was going to bite Teddy, but Rikki killed him. Later on, Nag tried to sneak inside the house and kill the family, he decided he was

Copperhead snakes who are female can reproduce asexually as well as sexually. I think that reproducing asexually is best for the species. Asexual reproduction is when one parent creates an offspring from themselves. There is no mating or mixing of genetics. Generally, there is no variation from generation to generation in population. Sexual reproduction is when two parents, a male and a female, create an offspring through sexual reproduction. While producing sexually would mean that they have different DNA from their parents and therefore wouldn’t have any diseases or hereditary issues passed down I still think asexually is more favorable for the copperhead snakes. Copperhead snakes are targeted because they can pose a threat to humans and therefore could very likely have their

which venomous snake is best known? Yep, you guessed it, the King Cobra (or as scientists call it Ophiophagus Hannah or snake-eater!!). Did you know that King Cobra are the only snake to lay eggs that they guard with all their life . They can also raise ⅓ of there body off the ground. They raise their body of the ground to make themselves look bigger to scare off enemies. The also hold a world record for longest tongue and they are not the most venomous snake in the world? They just eject the most venom into their prey.

Shark mating rituals vary from the size of the shark and its specie. In smaller, more flexible species, the male coils around the female, while the male of the larger specie orients himself parallel and head-to-head with the female (Woums & Demski 1993). Some species mating rituals also consists of males biting females on the pectoral fins or the middle of the back to hold on to them (Woums & Demski 1993). The female will often bear scars or marks, after the ordeal. Due to the fact that sharks are cold blooded animals, there is no precise gestation time. The development of the embryo will depend solely on the temperature of the water, however, the gestation period can last anywhere from 2 months to 2 years (Woums & Demski 1993). Within shark species there are two methods of reproduction. In some cases a female shark will lay eggs in a coastal nursery where the presence of other sharks are absent. And in other cases, usually in the larger sharks, females give birth to live offspring (Wourms & Demski 1993). In which case the young are born fully developed, and once they are born they shoot away fast or they risk being eaten.

A female Burmese Python will lay up to 207 eggs at once. Inside her nest, she will coil her body around the eggs to maintain a temperature of about ninety degrees Fahrenheit. Incubation takes around two months. The python has only just recently been observed engaging in shivering thermo genesis for the first time outside of captivity. This is the production of body heat through muscle contractions. The mother snake does this to raise the temperature of her nest and eggs- the warmer the incubation, the quicker they will hatch, and slither free throughout the forest, carrying on its destructive path. With this sort of reproduction, it’s no wonder they’re so easily taking over the Everglades.

Pregnancy is a nine month process and it starts when the sperm penetrates an egg. One and a half days later the single fertilised egg begins to divide. After two to three days there are enough new cells to make the egg the size of a pin head.

They exhibit a polygynous mating system, which means they have one-male and multi-female groups. The male’s large home ranges envelop the home ranges of several females. The males will mate with all the females in their home range and even some in extending home ranges. Females will also mate with members of different home ranges. The two remain together for several days while mating and will copulate several times in that period. Litters are usually fathered by one male, and the males will defend and mark their territory while mating. Females will mate every other year from May to August. They will stay in heat from June to August, and most mating will occur in June or July. Most interestingly females display a delayed implantation where the embryo is not implanted immediately at copulation but actually waits in diapause for about six months. Fertilized eggs develop to the blastocyst and will remain there until implantation to the uterine wall which typically occurs in the months from December to February. This means pregnancy may last anywhere from 120 to 272 days. Which will depend on when the embryo is fertilized and when it is implanted. Parturition is perfectly timed for the optimum survival of their young, which is usually when the most food is available. Females build snow-dens to birth and nurse their young. They typically have two dens, a natal den for giving birth and then when this den is

Once the snakes are caught, they go through a few different processes. First, they have their venom removed from

They are well taken care of and fed by their mothers for about two weeks. After three weeks, they are able to leave their nests and able to care for themselves but never leave far from their homes. They are born in liters of 5-6 mothers will reproduce anywhere from 25-30 baby cottontails within four or five litters (Bonner, 2005). They reproduce so quickly which is a great benefit for them because of the fact that most don’t make it past about a year of living. The Desert Cottontails do have the ability to live up to eight years with the few that do make it up to about 3 years. It takes a female about 30 days to reproduce a healthy litter with the differentiation of sex occurring on the 16th day. The full development for females of the ovules starts around day 21 and continues until birth (Bonner, 2005). Once the bunnies are born and go out on their own, they will claim their own home areas but will never leave completely from their original

Snakeheads are capable of spreading to many different areas and habitats. They do this by swimming underwater into other waterways. Snakeheads also have the ability to breathe out of water, so they can travel short distances on land to get to different areas. Even though snakeheads only breed when temperatures are warm, their eggs only take 1 to 2 days to hatch; causing quicker births of individuals.

Mongoose fight snakes, many snakes, but in this story, a little mongoose fights two King Cobras. Rikki Tikki, the little mongoose, defeats two King Cobras, Nag and Nagaina, that try to harm the family that is cared for by Rikki Tikki. Rikki Tikki was found by them because he was washed up by a storm and fell into a river. Both of these stories have an amazing perspective of a story. However, they are different to each other in some cases.

The male often bites the females nose (upper jaw) leaving it swollen and bloody. The wounds form pink scars, which can be used to identify if the otter is make or female. Otters have a gestation period of 4-9 months, or longer depending on the breed of the otter. Eurasian otters give birth in April or May. They can have up to about 6, or so, babies. Fresh water otters give birth on land or in dens. Sea water otters give birth in the water. Sea otter pups measure up to 56-61 cm. And fresh water pups can weigh up to 130 grams (4.6 oz.). A female otter has four nipples and her babies will nurse every 3-4 hours for 10-15 minutes. Mother otters are very protective over their young pups. The mother will float on her back in water carrying her pup on her belly and spend a great deal of time grooming/cleaning the pup. Baby otter pups often open their eyes after they're about a month old. All freshwater pups stay with their mother for about a year, until the next liter is born. By about four months of age the pups are able to swim and dive well enough to catch their own food and live on their own. Growth rate in otters differ depending on the species. Otters live up to 10-15

There are many methods of reproduction, but the two main methods are sexual and asexual, but which one is more efficient or beneficial. Sexual reproduction is the fusing of two gametes to produce an offspring. This form of reproduction is used by a lot of organisms, including us. Asexual reproduction is reproduction that only involves one parent. (“Pros and cons of sexual and asexual reproduction”). I am going to focus on asexual reproduction and the Desert Grassland Whiptail Lizard. This unique lizard uses asexual reproduction. Asexual reproduction is better for this species of lizards because it only requires one parent, it is less risky, and the population is only female.

They reproduce rapidly, as generally it is the case with small prey animals. No matter how well they are cared for, they possess somewhat short life span. Generally they have short gestational periods and their quick sexual maturity makes effective rodent control decisive. The reproductive cycle and the number of these rodent’s offspring increases with sufficient water, food and harbourage.
