There is no sea creature quite as cool as a sea cucumber. Sea cucumbers have no brains, hurl their internal organs at attackers as defence, and breathe through their rear ends. They’re bizarre. What is baffling too is how nutritious they are as food. This gelatinous delicacy is low-fat but rich in collagen, vitamin B3 and antioxidants. A regular intake helps lower cholesterol and blood pressure, improves liver and kidney functions, and reduces inflammation and risk of cancer.
