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.
Seagrasses are plants that grow underwater â but they are not the same as seaweeds (algae). Some species of seagrass look very much like terrestrial (land) grass, with straplike leaves or paired oval leaves. Places where many seagrass plants grow together are often called seagrass meadows or seagrass beds.oth seagrasses and algae (seaweeds) grow in the sea, but seagrasses are different from algae in several ways. â¢ Seagrasses produce flowers, fruit and seeds â algae produce different kind of âseedsâ called spores. â¢ Seagrasses, like terrestrial grasses, have separate roots, leaves and underground stems called rhizomes.
