1. The blue-green coloration of the blood plasma in some marine fishes, which is attributed to a protein bound tetrapyrrol (biliverdin), is an anomaly in vertebrates. 2.
This probably comes down to a genetic mutation, and means their blood carries 90 per cent less oxygen than red blood. They survive partly because frigid Antarctic waters are oxygen-rich.

Why is fish blood white?
Icefish blood is colorless because it lacks hemoglobin, the oxygen-binding protein in blood. Channichthyidae are the only known vertebrates to lack hemoglobin as adults. Although they do not manufacture hemoglobin, remnants of hemoglobin genes can be found in their genome.
How can a fish live without blood?
All vertebrates have red blood cells—that is, except for a small family of fish from the notothenoid family known collectively as “icefish.” These Antarctic-dwelling fish have translucent blood, white hearts, and have somehow adapted to live without red blood cells or hemoglobin.
As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.
Can fishes feel pain?
“Fish do feel pain. It’s likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.

What animal has the weirdest color blood?
Octopuses, lobsters, and horseshoe crabs use hemocyanin, which has copper instead of iron, and is blue instead of red—that’s why these creatures bleed blue. Other related molecules are responsible for the violet blood of some marine worms, and the green blood of leeches.
Answer: Brachiopods have black blood. Octopuses have a copper-based blood called hemocyanin that can absorb all colors except blue, which it reflects, hence making the octopus’ blood appear blue.
