The 72 species of seagrasses are commonly divided into four main groups: Zosteraceae, Hydrocharitaceae, Posidoniaceae and Cymodoceaceae. Their common names, like eelgrass, turtle grass, tape grass, shoal grass, and spoon grass, reflect their many shapes and sizes and roles in marine ecosystems.
What type of plant is seagrass?
Seagrasses are marine plants with the same basic structure as terrestrial (land) plants. They have tiny flowers and strap-like or oval leaves. They form meadows in estuaries and shallow coastal waters with sandy or muddy bottoms. Most closely related to lilies, they are quite different from seaweeds, which are algae.

- Found on shallow and intertidal mud/sand flats.
What is the most widely distributed seagrass?
Ruppia maritima
The most widely distributed seagrass is Ruppia maritima, which occurs in tropical and temperate zones in a wide variety of habitats. Seagrass bioregions at the scale of ocean basins are identified based on species distributions which are supported by genetic patterns f diversity.
What is the difference between seagrass and seaweed?
While seagrasses are considered vascular plants and have roots, stems and leaves, seaweed are multi-cellular algae and have little or no vascular tissues. The two differ in reproduction, structure, and how they transport nutrients and dissolved gases.
Can you eat seagrass?
“Can Eat or Not?” While we can’t eat seagrasses, the fruits of the Tape seagrass is edible and is eaten by native people in Australia. In some places, seagrasses are made into useful objects such as rugs and even roofing. Seagrasses are important nurseries for our seafood.
What kills sea grass?
Apply a herbicide such as copper sulfate to your pond to treat any remaining sea grass. Sea grass is very sensitive to the changes in minerals present in water, and will die if the mineral content changes suddenly. Copper sulfate should be applied at the rate recommended on the bag; the amount may vary between brands.
Who eats sea grass?
What animals eat seagrasses? Expand/Collapse What animals eat seagrasses? Sea turtles, manatees, parrotfish, surgeonfish, sea urchins and pinfish feed on Florida seagrasses. Many other smaller animals feed on the epiphytes and invertebrates that live on and among seagrass blades.
What is the scientific name of seagrass?
Zosteraceae. The family Zosteraceae, also known as the seagrass family, includes two genera containing 14 marine species. It is found in temperate and subtropical coastal waters, with the highest diversity located around Korea and Japan.
Is seagrass a plant?
Seagrass are flowering plants that grow entirely underwater
Light is required for the plants to make food through photosynthesis. Of the 60 species of seagrass found worldwide, seven grow in Florida waters.
What is the scientific name of seagrass?

Are seagrasses monocots?
The seagrasses are all monocots. The monocots are in turn divided into various subclasses or orders depending on the system being used.
What is sea grass called?
Seagrasses have been called “the lungs of the sea” because they release oxygen into the water through the process of photosynthesis. There are 26 species of seagrasses in North American coastal waters. They prefer to grow in shallow, sheltered, soft-bottomed coastal waters—both tropical and temperate.
Who eats sea grass?
Seagrasses are the primary food source for the world’s largest marine herbivores (manatees and dugong) and are a major food source for green sea turtles. Ducks, geese, and swans eat seagrass.
What is the lifespan of seagrass?
Seagrasses are flowering, saltwater plants that live in the shallow areas of an estuarine system. Most species of seagrass are perennials (recurrent, having a life span of two years or more) that are visible throughout the year.
What is seagrass used for?
Seagrasses perform numerous functions: Stabilizing the sea bottom. Providing food and habitat for other marine organisms. Maintaining water quality.
What kills sea grass?

Sea grass is very sensitive to the changes in minerals present in water, and will die if the mineral content changes suddenly. Copper sulfate should be applied at the rate recommended on the bag; the amount may vary between brands.
What is killing sea grass in Florida?
Phytoplankton blooms driven by nutrient pollution have been a significant factor in the reduction of seagrass beds in Florida coastal waters in the last 50 years.
