Mudskippers break the rules of fish biology by breathing through their skin, walking on their fins and thriving on land where water disappears twice a day.

A widely debated topic in biology and fisheries sciences is the role of oxygen in the growth of fish and other water-breathing animals. According to new research, developmental changes in individual ...

Sharks, skates and rays are oddities among fish: They have appendages growing out of the gill arches, small cradles of bones that supports the gills. This anatomical peculiarity has led to the ...

The paired limbs of humans, and before that the paired fins of fish, evolved from the transformation of gill arches in early fish, scientists say, presenting genetic evidence for this theory. Sharks, ...

A collaborative team of scientists recently found that there is no physiological evidence supporting a leading theory -- which involves the surface area of fish gills -- as to why many fish species ...

As you sit at your desk and chew your morning muffin, consider the complicated interlocking structure of your jaw. How did you manage to evolve such a thing? What you’re eating through is essentially ...

The outer ears that sit on the sides of your head share an unexpected genetic heritage with the gills of fish. According to research published in the journal Nature by scientists from the University ...

Scientists have traced the evolutionary origin of humans' outer ears to the gills of ancient fish through a series of gene-editing experiments. When you purchase through links on our site, we may earn ...
