Shoal grass is a perennial submerged aquatic herb that resembles land grass and is usually found in waters up to 40 feet deep. Although it can be found around the world, it grows predominantly throughout the southern United States and South America.
Shoal grass resembles land grass, with stiff, green, strap-shaped blades that grow up to 13 inches long. It produces egg-shaped fruits that are about 2 millimeters in size.
Shoal grass is usually found in waters up to 40 feet deep and is able to withstand prolonged exposure to low-tide conditions.
Shoal grass can be found worldwide. In the United States, it is distributed throughout the southern states, including Alabama, Florida, California, Louisiana, Mississippi, the Carolinas and Texas. It is also widely dispersed throughout South America.
Habitat destruction and motor damage pose the biggest threats to shoal grass. Increased sunlight following die-offs of turtle grass has caused a decrease in the light-sensitive shoal grass population.
Reproduction occurs through shoot and seed production and fragmentation.
