What do strange sea creatures raised in underwater hot springs look like?

It's such a strange group of creatures: there are blood-red tube-shaped worms, like **plastic tubes, the longest is 3 meters long, arranged horizontally and vertically, with blood-red granulation tentacles, capture and filter food from the water. These tube-shaped worms have no mouth, anus or intestine, and live by wriggling on the seabed using a tube. But it has hemoglobin in its body and its tentacles are filled with blood. There are surprisingly large crabs that have no eyes but can crawl everywhere; large, fat clams that have red blood in their bodies. They grow very quickly and are generally as large as the mouth of a bowl; like a dandelion flower. There are often dozens of living creatures interconnected, some are responsible for hunting, others are responsible for digestion, each has its own division of labor and is busysword but not chaotic. They are actually able to live happily at such a high temperature on the ocean floor. Scientists are surprised to call this place an “oasis of ocean exploration.”
