New research shows that epaulette sharks, often called “walking sharks,” can produce eggs without increasing their overall energy use.

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 ...

Not all creatures need to breed to produce offspring. Animals like zebra sharks and killifish are redefining what scientists thought they knew about asexual reproduction. Among vertebrates, or animals ...

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 ...
