What Is the Long String Hanging From My Fish?
If you have ever caught or cooked a fish, you may have noticed a long, thin string-like structure hanging from its belly. This mysterious appendage is known as the fish’s “string” or “belly flap.” It is commonly found in various species of fish, and its purpose has intrigued many curious minds. In this article, we will explore what this long string is and answer frequently asked questions related to it.
The Fish String: What is it?
The long string hanging from a fish’s belly is actually a remnant of its umbilical cord. Just like mammals, fish embryos are attached to a yolk sac during their early development stages. This sac provides the necessary nutrients for their growth until they are ready to hatch. After hatching, the yolk sac is absorbed into the fish’s body, leaving behind the umbilical cord, which gradually shrinks and dries up but remains visible on the fish’s belly.
