The Doppler Effect on the Red Shift Between the Distance Between Stars and Earth

Some species like the barramundi can go from saltwater to fresh water. They produce a membrane over their scales that prevents them from intergesting all the salt, and they actually turn into red eye barramundis. Bull sharks can also live in fresh water as well. And if you're in a river system that's mainly fresh water, you've got a lot of yummy food that you can eat. Thank you so much for joining us this morning.
