Seaweed
Seaweed or macroalgae refers to several species of macroscopic, multicellular, marine algae. The term includes some types of red, brown, and green macroalgae. Marine algae species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; ocean algae species from seaweeds to planktons play a vital role in carbon capture, producing up to 90 percent of the planet's oxygen. Understanding these roles provides guiding principles for conservation and sustainable use of seaweeds to take precedence over industrial exploitation. Mechanical dredging of kelp, for instance, destroys the resource and dependent fisheries. Certain species of seaweed are valuable for nutrition, biomedicine, bioremediation, and other uses.
Seaweed blenny
The seaweed blenny is native to shallow waters in the western Atlantic Ocean. Its range extends from New York southwards to Brazil, and includes the Caribbean Sea, the Gulf of Mexico, Bermuda and the Bahamas at depths down to about . A typical habitat is among limestone boulders and in scoops and basins where the rock surface is covered with a mat of algae, sea fans and other invertebrates. It is also found on reefs, in seagrass meadows and oyster beds, as well as around man-made structures such as pilings, jetties, seawalls, oil rigs and buoys, and among the roots of mangroves.
