Threats to Seagrasses: 1  Natural threats to seagrasses include storms, climate changes such as floods and droughts affecting water salinity, disruption of seagrasses by small predators as they search for food, and grazing by animals such as sea turtles and manatees.eagrasses may be confused with seaweeds (marine algae), but they are not. Seagrasses are vascular plants and reproduce by flowering and producing seeds. Marine algae are classified as protists (which also includes protozoans, prokaryotes, fungi and sponges), are relatively simple and reproduce using spores.
I was surprised by the level of threat to many species of seagrassâ. More common species are also in decline, meaning both seagrass habitat and diversity is being lost. Seagrasses provide food and habitat for a variety of ocean species including manatees, sea turtles and fish such as sea horses.Seagrasses are flowering plants that grow on the ocean floor.eagrasses face extinction threat. A manatee grazes on seagrass. Seagrasses around the world are disappearing, with some species now threatened with extinction. The first global survey of individual seagrass species has found that 14% are at risk of going extinct.
