Seagrasses don't just provide shelter for free-swimming animals, but also are a habitat for non-moving organisms, such as this sea anemone. Sessile animals attached to blades are called epibionts,...
Squids, octopuses and cuttlefish, such as this Australian Giant Cuttlefish ( Sepia apama ), compose just one group of animals that call seagrass beds home. Clams and worms bury themselves in the mud...
Giant kelp ( Macrocystis pyrifera ) is large, brown algae that grows in dense forests along coasts around the world. Long stalks anchor each plant to the seafloor, and they grow meters high like...
Hardy head silversides ( Atherinomorus lacunosus ) are abundant fish in shallow water seagrass meadows throughout the Indo-Pacific that often form shoals. They feed primarily on zooplankton and small...
Marc Frischer, a microbial ecologist at the Skidaway Institute of Oceanography , collects bacteria at the Smithsonian Institution’s field station in Belize. Smithsonian scientists and colleagues from...
A map that shows the location of mangroves throughout the world. They are mainly found in the tropics and subtropics. More about mangroves can be found in our Mangroves featured story .
Jellyfish and comb jellies are gelatinous animals that drift through the ocean's water column around the world. They are both beautiful—the jellyfish with their pulsating bells and long, trailing...
This mangrove island in the Pelican Cays, Belize, was clear-cut and filled with dredged sand and coral from the adjacent reef flat. Developers are clearing and dredging mangroves in an attempt to...
This view of mangrove roots above the water misses a lot of the action. The roots extend far below the water’s surface, anchoring the forest to the sea and providing a tangled habitat for a variety...
In this brief video clip from NOAA, catch a glimpse of the startling beauty and diversity of life found among deep-sea corals near the Aleutian Islands in Alaska. Explore more in the multimedia...
Around 100 million years ago, grass from land adapted to live and reproduce while submerged in seawater—the modern-day seagrasses. This sea invasion by land plants happened four separate times,...
Seaside sparrow ( Ammodramus maritimus ) chicks chirp and beg their parents for food from a well-hidden nest in a Gulf of Mexico marsh. Researchers from the Gulf of Mexico Research Initiative have...
In recent years, I have taken to watching flying fish along the Maine coast. Not the usual flying fish that skim over tropical seas, but fish dangling from the beaks of flying puffins. Puffins are...
In 1872, the United States did something remarkable. We set aside one of our greatest natural treasures, Yellowstone National Park , for future generations to enjoy and appreciate. The logic was...
The over 1,000 species of ribbon worms ( Nemertea ) are mostly found in marine environments (like the Hubrechtia found in a mud flat, in the photo). These worms have both a mouth and an anus (unlike...
In marshlands along the coast of the Gulf of Mexico, it's easy to hear the sharp, buzzing calls of seaside sparrows ( Ammodramus maritimus )—even if they can be hard to spot. These five-inch, brown...
