The Life Style of The Platypus Essay

only lay three to six. The eggs are incubated for about twenty-eight days, and the owlets usually fledge

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

The mating season is year round and once they’re pregnant the, length of gestation is one hundred thirty days to one hundred ninety days. (The gestation for a human is two times longer.) They only have one offspring at birth. After birth the young latch onto the backs of their mother and stay until a year of age.

For reproduction it is best to place one male in with 2-3 females. This will lower the rate of fighting compared to a one on one. Then the female will typically make a burrow 6-8 in. deep and lay her eggs there. The eggs will hatch about 60-70 days

Female Leafy Sea Dragons lay up to 250 bright pink eggs. Then, she deposits the eggs to the male’s tail with her ovipositor. Finally, the eggs attach to the brood patch which supplies the babies with oxygen.

Both the puffin and axolotl are colourful, have a distinctive featurette on their head (Axolotl has its colourful and feather-like gills, the Puffin has its brightly coloured horn-like beak), have special modifications to help the animal travel faster and more efficiently, they both eat small fish, and are commonly hunted and eaten by predators and humans. The population of both animals is distinctively decreasing, they both can live on land and swim in water, both reach the age of 15 and range up to 25 years old (the puffin can be older than an axolotls average age, but the age is close to one another), and are extremely adorable. There are not as many similarities as differences, but there are at least some. The axolotl and puffin may not be that similar, but using these animals as examples can show us that how the classification method works and why we use it. We have found some similarities but more differences, and this shows why the axolotl and puffin are not related through classification.

They are solitary creatures who remain submerged for most of their time at sea making difficult to study their behavioural tendencies.

As we swim, let me give you some information about me and JJ. We’ll start with our moms. Female turtles lay about 140 eggs at a time. They lay eggs between July and October. To do this they swim up to a beach in Puerto Rico, Mexico, Costa Rica, Cuba or

Mating occurs before sunrise and mates are found by scents. When the female lays her eggs it forms a stick that contains thirty to fifty eggs. They hatch after about twenty-five days and they eat the cactus pad. After about two moths in the host cactus they exit the cactus and form cocoons. They become a pupa under the debris on the ground. Once they reach the moth stage they search for a
