Common name: Turtle Grass

General information

Turtle Grass, scientifically known as Thalassia testudinum, is a widely recognized seagrass species found in the Caribbean Sea, Gulf of Mexico, and along the North American east coast down to Venezuela. It is a key species in its habitat, forming extensive meadows that are crucial for the ecosystem. Turtle Grass has long, ribbon-like leaves that can reach up to 14 inches in length and provide important shelter and food for a variety of marine life.

Care

In the aquarium, Turtle Grass requires a deep sand bed for its roots to anchor and spread. It thrives under moderate to high lighting conditions that simulate its natural sunny habitats. Adequate water flow is also necessary to prevent detritus from settling on its leaves. While it can be a challenging species to keep, its presence can greatly enhance the naturalism and biodiversity of a marine aquarium.

Symbiosis

Turtle Grass beds are vital habitats for many marine organisms. They offer a nursery ground for juvenile fish and invertebrates, while also providing food for herbivorous species. In the aquarium, they can form a symbiotic relationship with detritivores that help keep the leaves clean and healthy.

Habitat

T. testudinum is typically found in shallow, clear waters where sunlight can penetrate to the seafloor, allowing photosynthesis. It prefers sandy substrates and is often found at depths ranging from just a few inches to several feet, depending on water clarity and light availability.
