The Yellow Sea Cucumber or Colochirus robustus is a type of sea cucumber. It’s like a soft, squishy tube that lives in the ocean.
Yellow Sea Cucumber is part of a group called Holothuroidea. This group is known for doing some really weird things like spitting out their insides, making babies without a partner, and being able to grow back parts of their bodies.
The Yellow Sea Cucumbers don’t have a spine, but they do have a kind of skeleton inside them made up of tiny pieces called spicules. They use their butt to breathe, which is pretty funny.
People in some parts of Asia eat Yellow Sea Cucumbers and think they can make you healthy.
What Does the Yellow Sea Cucumber Look Like?
The Yellow Sea Cucumber is kind of like a fat, bumpy yellow tube. It can grow up to 7 centimeters, or about 2.8 inches long.
Yellow Sea Cucumber has 5 shallow lines running along its body and sticky-out bits that look like fingers or thorns.
At one end, the Yellow Sea Cucumber has a circle of big, feathery things that it uses to catch food. On its belly, it has 3 lines of tube feet that it uses to hold onto things.
The color is a bright yellow, sometimes with gray in between the bumps.
Where Does the Yellow Sea Cucumber Live?
You can find the Yellow Sea Cucumber in warm ocean water around the middle of the Pacific and Indian Oceans.

What Is the History of The Yellow Sea Cucumber?
Sea cucumbers have been around for a super long time, like 400 million years.
They can be found all over the world in the deepest parts of the ocean, but there are lots of different types in the shallow water of the Pacific and Indian Oceans.
That’s where the Yellow Sea Cucumber lives. All the different types of sea cucumbers are related and come from the same ancestor.
What Is the Behavior of The Yellow Sea Cucumber?
The Yellow Sea Cucumber likes to live on rocks and reefs where the water moves a lot. It holds onto the rocks with its tube feet and uses its feathery things to catch tiny animals and other stuff floating in the water.
Sometimes, when times are tough, the Yellow Sea Cucumber can make babies by splitting itself in half. Each half then grows the parts it’s missing.
Yellow Sea Cucumber can also spit out its insides to escape from enemies. But that only happens when it’s really stressed out.
What Are the Uses and Benefits of The Yellow Sea Cucumber?
The Yellow Sea Cucumber is sometimes kept in fish tanks because it looks cool. But it’s not easy to take care of because it can release poison if it gets stressed out and needs special food.
For hundreds of years, people in Eastern countries have used Yellow Sea Cucumber as medicine. Recent studies show that eating it can make your immune system stronger. That means it can help your body fight off sickness.
Yellow Sea Cucumber can also help wounds heal faster and reduce pain from arthritis. Plus, it’s packed with lots of vitamins and minerals that are good for you.
