below are the names of animals that are sometimes considered to be ruthless in parenting that I got from apakabardunia.com
1. Beetles diggers (Burying Beetle)
Mother beetles will feed each of her children, one by one. However, when the amount of food runs out, then the last child is not only not received food rations, but also would be eaten alive by her mother.
Beetles diggers usually stay in the dead rats. And mother always Beetles lay eggs with the number more than the amount of food available (dead mouse), then to increase the opportunities to grow larger for all the family, the number of children must dicukupkan with the amount of food, not vice versa.
2. Panda
Mother Panda will only keep one child, if he has more than one, then others will be left so alone in the wild. While the 'beloved children' grow up healthy with adequate food intake, while other children will emaciated helpless.
Mother Panda is not possible to provide food for a second or subsequent child, so during the first 8-9 months (after that child pandas can find their own food), kids panda that can not be enough food (including milk) must survive on its own, if not they will surely die.
3. Hamster
Hamster mothers often memkan her own. Hamster mothers usually give birth a few children, if there are children who are not perfect (defect) or considered not pass the 'quality control' will be eaten alive, can also be caused if the amount of food available is considered not to meet the needs of themselves and their children.
4. Black Eagle
Mrs. Eagles usually leave when her children playing in the nest, though often times the game can result in death for one of her children.
The amount of food available at times not many, and difficult to obtain. Thus the mother eagle let this dangerous game, as a test for, children, the strong survive.
5. Rabbit
Mother Rabbit will instantly leave her children in the holes after they are born, and during the first 25 days, the mother will only 'see' and feed their children no more than 2 minutes per day.
Son of a rabbit is a soft and tempting food for predators, so it means the mother is always trying to hole his residence a secret, the way with the least possible time spent near the hole. After the 25 days before the children can find food themselves rabbits.
