Aestivation has been put forward as the most likely explanation why this therapsid cynodont Thrinaxodon liorhinus shared its burrow with a temnospondyl amphibian, Broomistega putterilli. [11] Non-mammalian animals that aestivate include North American desert tortoises, crocodiles, and salamanders.
The larval stage of insect development is considered by some to be a form of altricial development, but it more accurately depicts, especially amongst eusocial animals, an independent phase of development, as the larvae of bees, ants, and many arachnids are completely physically different from their developed forms, and the pre-pupal stages of ...
The word is most often used for the offspring of mammals, but can be used for any animal that gives birth to multiple young. In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch, while young birds are often called a brood. Animals from the same litter are referred to as littermates.
A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.”
Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs . The practice has been observed in many species throughout the animal kingdom, especially primates ( primate infanticide ) but including microscopic rotifers , insects , fish , amphibians , birds and mammals .

A white-fronted capuchin sits in a tree. Cases of infanticide in white fronted capuchins have been attributed to resource competition. Infanticide in non-human primates occurs as a result of exploitation when the individuals performing the infanticide directly benefit from consumption or use of their victim. [1]
Gov. Bill Lee proposed $3 million for a maternal health program that will now go to controversial crisis pregnancy centers.
Parental care is a behavioural and evolutionary strategy adopted by some animals, involving a parental investment being made to the evolutionary fitness of offspring. Patterns of parental care are widespread and highly diverse across the animal kingdom. [ 1 ]
