Spotlight on Spinosum

Nature's Versatile Resource

Spinosum (Eucheuma denticulatum) is a remarkable red seaweed species native to the warm, clear waters of the Indian Ocean. Cultivated along Tanzania's pristine coastline, this distinctive marine plant is characterized by its reddish-purple branches and characteristic spiny texture—a natural design that maximizes its surface area for nutrient absorption.
