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 ...

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 ...

When you and I take a deep breath, we pull air into our lungs. That’s because humans are mammals. But fish aren’t mammals. They usually don’t breathe air. They usually don’t have lungs. That’s what I ...

Have you ever heard of a fish that breathes air and “hibernates” to survive? The lungfish is an incredibly unique and resilient fish that has developed lungs to extract oxygen from the air. However, ...
