When speaking of the greatest athletes in the world, you may think of the names like Usain Bolt or Yohan Blake generally. It's amazing that scientists now find the greatest athletes may be the in the water and covered in scales through study using recombinant proteins - They are fish.
They discovered that fish are far more effective at delivering oxygen throughout their body than almost any other animal. This advantage gives them the athletic edge over other species.
"Fish exploit a mechanism that is up to 50-times more effective in releasing oxygen to their tissues than that found in humans," says study lead author, Dr Jodie Rummer from the ARC Centre of Excellence for Coral Reef Studies at James Cook University.
Haemoglobin in fish, the protein in blood that transports oxygen, is more sensitive to changes in pH than ours and more than the haemoglobins in other animals. It is quite important for fish during times of stress, to escape from predators, or when they are living in water that is low in oxygen. They can double or even triple oxygen delivery to their tissues during these critical times.
In the last decade, researchers have been using rainbow trout to investigate oxygen delivery in fish. They first discovered and tested this mechanism by monitoring muscle oxygen levels in real-time in trout. Now they have determined just how powerful that system can be and have compared the results with medical studies on humans.
It shows us how fish have adapted this very important process of getting oxygen and delivering it to where it needs to be so that they can live in all kinds of conditions such as warm or cold water, or nd water with high or low oxygen levels. For these athletic fish, enhanced oxygen delivery may be the most important adaptations during their long evolutionary years.
