In Nova Scotia, the invasive exotic green crab (Carcinus maenas) destroys eelgrass when it digs in the substrate for prey items, or by directly eating eelgrass seeds. The decline of eelgrass in Antigonish Harbour has resulted in fewer Canada geese , which feed on the rhizome, and fewer common goldeneye , which eat invertebrates that live in eelgrass meadows.
We surveyed predation intensity on common prey (live amphipods and gastropods) in communities of eelgrass. (Zostera marina) at 48 sites across its Northern

It is a hermaphrodite, meaning it has Jan 1, 2014 A large eelgrass (Zostera pacifica) meadow was present at Frenchy's in seagrass beds: a review of the influence of plant structure and prey Jan 2, 2017 Figuring out reliable ways to grow more eelgrass could revitalize these of their body weight in prey every day — impacted eelgrass growth. Most of the animals that live in seagrass meadows do not eat the seagrass itself. Rather, they eat the algae that grow on it, or prey on each other. The exception Prey selection and the functional response of sea stars (Asterias vulgaris Verrill) on the growth, survival, and light attenuation of eelgrass (Zostera marina).

Kelpfish and grass shrimp are abundant predator and prey organisms in Southern California eelgrass habitat, with densities of approximately 0.5–1 m − 2 and 100–500 m − 2 in San Diego Bay eelgrass, respectively. Grass shrimp compose up to 20% of the biomass in kelpfish guts (Moore and Hovel, 2010).

Green sea turtles are the only vegetarian sea Jul 8, 2015 Eelgrass provides structure for many species of invertebrates and algae, which young fish then prey on in the shelter of the grass's blades, Aug 10, 2014 Clinging to an eelgrass blade near you and then spreads its stinging tentacles to capture prey (e.g., small crustaceans such as copepods).

Manatees are large aquatic mammals that feed primarily on seagrass.
Mild wave action, abundant nutrients, and protection from predators make them sanctuaries for zooplankton and small fish. The bay pipefish’s long, slender, green body perfectly mimics the swaying eelgrass blades, making it both an elusive prey and a stealthy predator. Eelgrass (Zostera marina) is a key foundation species in estuaries and coastal seas across the northern hemisphere (30° to 67° latitude), and thus provides a unique opportunity to test latitudinal gradients in ecological processes within communities of a single habitat‐forming species, minimizing potential confounding factors in prior biogeographic studies. Eelgrass has thick, creeping rhizomes with many roots and nodes. Predators.

We sampled eelgrass blades and sediments across a gradient of eelgrass density, hypothesizing that the structure of eelgrass would provide habitat for a variety of juvenile salmon prey.
We also hypothesized that niche space would increase with eelgrass density, leading to increased inverte-brate abundance, and that species assemblages in sparse
To test whether colonization of eelgrass by bryozoans affects prey (grass shrimp) relative survival, we tethered grass shrimp within naturally occurring eelgrass habitat in south San Diego Bay (32.626, −117.107).

Without it, scientists say, there would be precious few salmon or herring, and little prey for orcas. It means hundreds of millions—perhaps billions—to the local economy, and chances are, most Puget Sound residents have never heard of it. It is eelgrass, and there may be no plant more central to Puget Sound’s environmental wellbeing.
