It has been said that when dolphins bleed under water
that their blood is green. Is this true? If so Why? Thank you Alex
It is a matter of light, not of the actual color of the blood. Dolphin blood
is red, just like ours. However, water is actually slightly colored, and
lets blue light through better than red light. Below about 30 feet, so
little red light remains thateverything that is actually red appears green
