When you see the third one, you may wonder: Is this the kind of fish that avatars usually eat?
In fact, this fish is called snakehead, is the only existing snakehead, is a rare species of fish found on the west coast of North America, is an important commercial and recreational fish. The fish also begins with an American named Jim Russell. As an experienced dive fisherman, he could be said to have fished the depths of the ocean and been around a hundred fish.
Now, just after recovering from a knee injury, he couldn't help but take the boat out for another dive. After diving into the deep sea, Russell found a fish in a rocky crevice, and after several attempts, he managed to spear the black fish and bring it to shore.
Just as Russell was happily disemboweling the fish, he got a shock when the knife went down.
"Crap, why is this fish flesh blue?"
Although it was strange, Russell and his family shared the hard-earned blue-fleshed sea fish, and after the meal, he didn't forget to post a video of his fishing and dissecting the fish on his Ins page, so that netizens could also have a good time.
"Forked up a beautiful snake cod, filleted and ate it on the same day," and "Great catch. Found it in a dark narrow crevice and brought it back."
It doesn't matter what color it is, the internet's main concern is:
(On a different note, how does it taste?)
This netizen's foodie attributes are exposed, the taste is of course "very delicious" ah!
All this to say, why is cod blue?
About 20 percent of cod have blue or bluish-green flesh because of something called cholorophyll in their blood, which turns their flesh blue or bluish-green, but doesn't change the taste or the nutrients. So far, of course, there is no direct evidence of this, so it's just a human guess.
After cooking, the color fades and they turn back to their normal white color.
While they are called cod, it is named solely for their resemblance and nothing else.
It is a member of the six-lined fish family and the only extant species of the subfamily Serpentodontidae. Snake cod have 18 canine-like teeth, which is why they're also called long serpentine monoclines, which makes them omnivorous fish that will eat just about anything. Whether it's a small octopus or a large rockfish, whether it's shelled or unshelled, it's all in their stomachs first, and the sheer volume of food is breathtaking.
They are mainly distributed in the west coast of North America about 10 meters -100 meters deep in the rock pile, the deepest can reach more than 475 meters of the sea. Though very edible, they do not grow meat as recklessly as catfish, averaging just 45 centimeters, or 150 centimeters at the end of its life. Its liver is rich in vitamin A and its meat is tasty, making it a popular species for swimming and commercial fishing.
But if you want to get a taste of what bluefish meat tastes like, it's a matter of luck. There's no telling though, with a one in five chance of it being even harder to catch, it's easier than winning the lottery!
