Selva (sargassum)

Selva, known as sargassum, is a type of floating seaweed found in large quantities in the ocean, particularly in the Sargasso Sea. It forms dense mats that drift across the water surface, providing vital habitat for marine life such as fish, turtles, and birds. Sargassum also plays a role in ocean ecosystems by producing oxygen and absorbing nutrients. However, excessive sargassum blooms can pose challenges for coastal communities, affecting tourism, fishing, and marine health when these mats wash ashore in large amounts. Overall, sargassum is an important, naturally occurring component of ocean ecosystems.
