Zostera marina

Zostera marina L.

Eelgrass, Seawrack

Zosteraceae (Eel-Grass Family)

Synonym(s): Zostera marina var. latifolia, Zostera marina var. stenophylla, Zostera pacifica

USDA Symbol: ZOMA

USDA Native Status: L48 (N), AK (N), CAN (N), SPM (N)

This grasslike marine herb is a seed plant, its leaves stream with the current.

Neither a seaweed nor an algae, Eelgrass is a true seed plant that has evolved an ability to live in saline waters. Currents distribute both pollen and the small fruit; propagation also occurs by means of rhizomes underneath the mud or sand. Unlike marine algae, it offers no resistance to attaching organisms, so the outer half of each blade usually is coated with a wide variety of very small marine plants and animals. Eelgrass beds are havens for scallops, crabs, and many fishes.
