Some animals starve to death shortly after birthing their young while others are eaten by their own young -- but these mothers make the ultimate sacrifice. Click through for 10 animal mothers that ...
Quokkas are nocturnal animals; they sleep during the day in Acanthocarpus preissii, using the plants' spikes for protection and hiding. [9] Quokkas have a promiscuous mating system. [10] After a month of gestation, females give birth to a single baby called a joey. Females can give birth twice a year and produce about 17 joeys during their ...
Vertebrate maternal behavior is a form of parental care that is specifically given to young animals by their mother in order to ensure the survival of the young.

Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring. [1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.
To allow the mother to dive and gather food and resources, the whales in their social group separate their dives allowing for the baby to be monitored and overseen by a whale during all times. [6] Superb starlings also perform this behavior. Their group living situation contributes to many potential parent figures in the young's life.
The morphological features of the placenta differ among species, but the function is universal. The behaviour is characteristic to the mother of the majority of placental mammals. [1] Significant documentation has been provided on placentophagy in a range of animals. Anomalies generally include humans and aquatic species, as well as camels. [2]
The mothers remained with their offspring, which suckled on a white, viscous liquid from their cloaca, experiencing rapid growth in their first week. This milk-like substance, rich in fats and carbohydrates, is produced in the mother's oviduct epithelium's hypertrophied glands, similar to mammal milk. The substance was released seemingly in ...
