Live Green Slime (Enteromorpha spp.)
Please note this is a live marine specimen.

Green Slime (Enteromorpha spp.), also known as green filamentous algae, is a bright, vibrant seaweed commonly found along Maine’s sheltered clam flats, cobbly shores, and hard mud intertidal zones. Its fine, tubular fronds thrive in nutrient-rich shallows and are often among the first algae to appear in spring. This species plays an important role in coastal ecosystems, serving as habitat and food for invertebrates and juvenile fish. Sustainably hand-harvested from the Gulf of Maine, Green Slime is ideal for aquariums, marine ecology demonstrations, and classroom studies on algae growth and intertidal ecology.

Key Facts:
Common name: Green slime
Scientific name: Enteromorpha spp.
Location: Sandy and cobbly sheltered clam flats; hard mud, mid-intertidal
Seasonality: Available all year (best in spring – fall)
Color: Bright green
Size: 4” – 6” fronds, sometimes longer
Collected: By hand
Quantity: Sold by the pint volume
Note: This is a live marine specimen. Natural variations in size, color, and appearance from photos should be expected. If you would like any specimen preserved, please send a request to: info@gulfofme.com

Green slime forming a dense mat around clam holes.

Green slime forming a dense mat around clam holes.

Tidepool Tim says, “Green slime is an invasive species in our waters that seems to form dense mats on the mud flats when the conditions are right. Shallow protected coves get the most growth of this green algae. In the fall, storms will windrow the fronds and push them toward the high water mark relieving the intertidal areas of this pest. In summer months, soft-shell clams can be suffocated by the covering of this seaweed. Often the clams will come to the surface of the flats in order to survive this covering of seaweed. Gulls and other predators will have a heyday eating these now exposed clams.”
