Seagrass beds are home to small creatures called epifauna that help connect plants and animals. Scientists studied how these creatures change with the seasons and different factors in Japan. They found that in spring and autumn, the environment plays a bigger role in shaping the epifauna community. But in summer, the creatures living on the seagrass blades become more important. Surprisingly, the environment mattered more in spring and summer, while the creatures on the seagrass blades were key in autumn. This shows that these blade-dwelling organisms are crucial for the whole community, even though they are not as big as the seagrass or tiny algae.
