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.
A baby kangaroo, known as a joey, inside their mother's pouch. Altricial young are born deaf, blind, almost completely hairless and have very limited motor functioning. [1] The maternal behavior in these species is primarily focussed on providing warmth for the young since they are unable to thermoregulate. [4]
Mouthbrooding is the care given by some groups of fish (and a few other animals such as Darwin's frog) to their offspring by holding them in their mouth for extended periods of time. Mouthbrooding has evolved independently in several different families of fish including the cardinalfish , sea catfish , bagrid catfish , cichlids , snakeheads ...
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 ...
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]
A Hanuman langur mother feeding an infant. Female Hanuman langurs are known to utilize paternity confusion through concealed ovulation. To protect their young from infanticide, many species of primate mothers will form social monogamous pairs to prevent paternal infanticide. In these pairs, the males will mate with other females but live ...
Maternal infanticide occurs when newborn offspring are killed by their mother. This is sometimes seen in pigs, [47] a behavior known as savaging, which affects up to 5% of gilts. Similar behavior has been observed in various animals such as rabbits, [48] hamsters, [49] burying beetles, [50] mice [51] and humans.
It is a complex social behaviour in vertebrates associated with animal mating systems, life history traits, and ecology. [1] Paternal care may be provided in concert with the mother (biparental care) or, more rarely, by the male alone (so called exclusive paternal care).
