Animal reproduction and breeding encompasses the full spectrum of natural, assisted and genetic processes that underpin the perpetuation, improvement and conservation of species across diverse taxa.

What are some animals that give birth to huge numbers of offspring at once?” (Watch a female sea urchin produce millions of eggs.) The mola, or ocean sunfish, looks like an animal cracker someone bit ...

A new study published in Science and led by Monash University biologists reveals that the energy cost of reproduction is far greater than previously believed. The research, led by Dr. Samuel C Ginther ...

Nature is full of evolutionary selflessness. From deep-sea octopuses to certain marsupials, there are animals and insects ...

The energy invested in animal reproduction is as much as 10 times greater than previously estimated when the metabolic load of bearing and caring for offspring is accounted for, according to a new ...

There's no rule that regulates how animals obtain the necessary genetic material to reproduce—and as a result, there is a lot of weird animal sex going on out there ...

Studying a species of beetle mite, an international research team has demonstrated for the first time that animals can survive over very long periods of time (possibly millions of years) entirely ...

Animals possess circadian clocks, or 24 h oscillators, to regulate daily behavior. These typically take their cues from the periodic change of sunlight and darkness. However, many animals are also ...
