Why do some snakes leave their babies after birth?
![Picture](/uploads/3/7/0/1/37017767/2675008.gif?250)
Most snakes don’t usually protect their babies after giving birth. Some female snakes give birth to live young and some lay eggs. The female snakes lay their eggs and leave them to hatch on their own, with the one of the exception being the king cobra, the only species of snakes that build an nest around them. Most of the pythons will also wrap around their eggs until the eggs hatch, once the babies move they are ready to leave and have there life and go their separate ways. After the babies move away, the mother loses her interest in them and has no care for them. It is not necessarily mean the mother is around once the baby is born. Snakes aren’t really like other animals and not all animals always keep watch over their young. Female snakes keep their young near them for more than four after hatching and these snakes like their mother’s protection from potential predators.

What are the advantages and disadvantages of internal fertilization compared to external fertilization? examples of animals that use each method
Internal fertilisation: mammals, birds, reptiles, sharks, arthropods and worms. External fertilisation: most fish, bony fish, frogs, coral and slug. External advantages: - The advantages in the external fertilisation is that lots of egg cells are produce. - Larger numbers of offspring - Easier to find mates as the gametes released - More genetic variation External disadvantages: - Are that a small number survive - Environmental hazards such as predators reduce the change of surviving into adulthood - Large amounts of gametes go unfertilised - It is not guaranteed that the sperm will come in contact with eggs - Greater chance of desiccation of gametes Internal reproduction: - The increase of gametes meet - Greater change of successful fertilisation - More protection against outside environments and predators and therefore a higher chance of surviving until birth - More selective their mates - Less chance of desiccation of gametes Internal Disadvantages: - Harder to bring both male and female into intimate contact - Limited amount of offspring being produced at any given time - Higher risk of sexually transmitted diseases being passed on Biblography http://pets-animals.blurtit.com/2604087/how-do-mother-snakes-take-care-of-their-young https://au.answers.yahoo.com/question/index?qid=20090907215104AALFg8z http://www.reptilesmagazine.com/Reptile-Care-For-Beginners/Snake-Myths-And-Facts/ http://www.care2.com/greenliving/8-animals-that-mate-for-life.html?page=8 http://www.mnn.com/earth-matters/animals/photos/11-animals-that-mate-for-life/french-angelfish http://terrific-top10.com/2013/02/11/top-10-animals-that-mate-for-life/ http://www.pawnation.com/2013/02/11/12-animals-that-mate-for-life/ https://www.boundless.com/biology/animal-reproduction-and-development/fertilization/external-and-internal-fertilization/ http://www.shmoop.com/animal-reproduction/fertilization.html http://wiki.answers.com/Q/List_of_animals_that_have_internal_fertilisation http://wiki.answers.com/Q/Give_example_of_animal_that_do_internal_fertilization_and_external_fertilization |
