Ocean's Delicacies: Exploring the World of Echinoderms
Sea urchins and other echinoderms are spiny, marine invertebrates that belong to the phylum Echinodermata. They have a round or oval-shaped body covered in spines and a mouth surrounded by five symmetrical jaws. Sea urchins are known for their vibrant colors, ranging from purple and green to red and black. Their texture is soft and creamy, while their taste is often described as briny and slightly sweet, with a hint of oceanic umami. Other echinoderms, such as sea cucumbers and sea stars, have different appearances and textures but share a similar marine essence.
Origins and history
Sea urchins and other echinoderms have a long history of culinary use in various cultures around the world. They have been consumed for centuries in coastal regions of Asia, Europe, and South America. In Japan, sea urchins, known as "uni," have been a delicacy for over a thousand years and are highly prized for their rich flavor. In Mediterranean cuisine, sea urchins are often used in pasta dishes or enjoyed raw. Sea cucumbers, another echinoderm, have been used in traditional Chinese medicine for their supposed health benefits.
Nutritional information
Sea urchins and other echinoderms are rich in protein, omega-3 fatty acids, and minerals such as calcium, magnesium, and zinc. They are also low in calories and carbohydrates.
Allergens

How to select
When selecting sea urchins and other echinoderms, look for specimens that are firm and have intact spines. Avoid any with a strong fishy odor or signs of discoloration. For sea cucumbers, choose ones that are plump and have a smooth, unblemished skin.
Storage recommendations
Sea urchins and other echinoderms are highly perishable and should be consumed as soon as possible after purchase. If necessary, store them in a cool environment, such as a refrigerator, for a short period. However, it is best to enjoy them fresh.
How to produce
Sea urchins and other echinoderms are typically harvested from the ocean. Cultivating them is a complex process that requires specialized facilities and knowledge, making it challenging for amateurs to produce them.
Preparation tips
To prepare sea urchins, carefully crack open the shell using a pair of kitchen shears or a sharp knife. Gently scoop out the bright orange or yellow roe, known as "uni," and rinse it under cold water. Sea urchin roe can be enjoyed raw, added to sushi or sashimi, or used as a flavorful garnish for pasta, risotto, or seafood dishes. Sea cucumbers are often braised or stir-fried in Asian cuisine, while sea stars are primarily used for decorative purposes and not consumed.
