5. Sea turtle hatchlings swim offshore to sargassum rafts, which provide them with food and refuge for their first few years.
6. Sargassum habitat also provides food, refuge and breeding grounds to birds, crabs, shrimp and fish, serving as a nursery for mahi mahi, jacks and amberjacks.
7. Sargassum is often found floating among large plastic items along ocean currents. The sun’s ultraviolet rays can break down the plastic into smaller fragments known as microplastics, which young sea turtles often ingest.
8. Sargassum sinks to the seafloor once it loses its buoyancy, providing energy in the form of carbon to deep sea fish and invertebrates.
