What Is Sea Urchin?

The sea urchin (often called by their Japanese name, Uni) has Echinoidea, an animal living in the sea in the echinoderm division. A sea urchin is a creature that lives in the oceans. They are widely distributed throughout the world's seas but are most concentrated in tropical climates.

Sea urchins do not live alone but often gather in groups and groups to create biomes. Areas with a lot of sea urchins are hollows, rapids, carpets of seaweed, and algae in warm seas.

Sea urchins move rather slowly, and their food is usually seaweed. However, when living in some seas, they can eat certain mollusks, corals, or certain types of mollusks seagrasses.


In terms of external features, the sea urchin has a shape that is not much different from the terrestrial urchin when curled up. The sea urchin shell is spherical and has many sharp spines on the outside. That's why they are also called urchins.

The body diameter of sea urchins ranges from 3 to 10cm, and some individuals have larger sizes. Their spines grow pretty thick on the outside of the shell, with a length of 3 - 5 cm. The color of sea urchins is also very diverse. They can be black, dark brown, purple or white.

On the outer surface of the sea urchin's shell, there are mouth and anal openings that help them eat food and excrete feces. The sea urchin's mouth usually has 5 teeth and is surrounded by many small bones.


The flesh inside the sea urchin is quite small and is called buttery sea urchin. This buttery is usually divided into 5-8 small wings evenly distributed inside the sea urchin's body with an arc shape. Buttery sea urchin is yellow-orange or orange.

The meat of sea urchins is not poisonous, but their spines contain toxins. This is a weapon for them to fight against the enemy. If a person steps on the spines of a sea urchin, the first will scratch the skin, and the second will feel numb.

How to Open Sea Urchin?


Opening sea urchin is not too difficult

Preliminary processing of sea urchins and opening them is not too difficult. However, you need to pay attention to a few things to make opening sea urchins easier:

  • You should wear rubber or cloth gloves to avoid being pricked by sea urchin - sea urchin spines.
  • Before preliminary processing, you can clean sea urchins by washing under running solid water to remove sand and dirt.
  • Step 1: Use scissors to cut the spines around the outer shell of the sea urchin.
  • Step 2: Use the tip of scissors to cut in a circle at the bottom of the sea urchin.
  • Step 3: Pour all the water inside the sea urchin to expose the buttery part. Then, tweezers pull out the blood veins and food left inside. Leave only the yellow or orange flesh.
  • Step 4: Wash and rinse under running water before enjoying or processing.


How to Store Live Sea Urchin?

The porcupine will taste its best when fresh. At this point, buttery and its flavor will be at their best. Therefore, many people want to keep sea urchins alive until processing.

The simplest way to keep sea urchins fresh is to store them in cool water at 40 degrees F. You can keep sea urchins fresh for up to 48 hours at this temperature. Sea urchins should not be left for too long outside. It is easy to die and lose its nutritional value. Try to eat sea urchins as soon as you catch them from the sea.

Live sea urchins should not be stored in the refrigerator. The temperature of the refrigerator will solidify the sea urchin's buttery. Plus, once defrosted, buttery will break down and lose water.

How To Preserve a Sea Urchin?

When you want to store buttery after it has been processed and peeled, separate each buttery from the shell, place it in a tray, and wrap. Then put it in the freezer if you want to keep it for a long time. If you're using it right away, you can keep it in the fridge.

How to tell if a sea urchin is dead?

Choose live sea urchins. You can see they breathe easily by looking at the spines that move in the presence or absence of water. Most sea urchins have their spines intact, and when the spines move, it's still alive.

However, the sea urchins lost their spines, no longer breathing or moving. When you pick them up and find them relatively light, they may be dead. By then, the buttery inside them has changed color and is no longer delicious.
