Smaller remoras also fasten onto fish such as tuna and swordfish, and some small remoras travel in the mouths or gills of large manta rays, ocean sunfish, swordfish and sailfish. The relationship between a remora and its host is most often taken to be one of commensalism, specifically phoresy

Have you ever wondered what an alien invasion looks like underwater? These spiny creatures are lionfish, and they are taking over the Atlantic. The lionfish invasion may pose one of the greatest ever man-made threats to Atlantic coral reefs. After being first released from aquariums in the 1980s, lionfish have aggressively invaded habitats in the Southeast United States, the Caribbean Sea, and the Gulf of Mexico. Right now, the best way we have of dealing with the lionfish problem is killing them by spearfishing. It’s easy and effective, but only in fairly shallow water, and only in areas frequented by divers. Hollings Scholar Emily Wallingford spent this summer working with lionfish expert Dr. James Morris. They were searching for ways to make lionfish easier to catch without having to rely on the continual effort of divers. I’ve been doing tank experiments this summer. Testing to see if lionfish have a preference between horizontal and vertical structures. What we’re going to try to do here is learn more about lionfish behavior and their affinity and attraction for these types of structures and exploit that using these devices that will hopefully allow us to aggregate lionfish and increase efficiency for spearfishers. Here is the horizontal structure we’ve been using in the tanks, and then the vertical structure is in the tree shape over there. What I do is set up individual and group experiments with these two devices to see if the fish spend more time on the horizontal structure versus the vertical structure. We still have quite a bit to learn about lionfish. These ruthless invaders are changing the aquatic landscape throughout Atlantic marine environments. Emily’s research will aid scientists in the greater fight against lionfish. It's one battle in a larger war. Stay tuned next week to learn more about what we are finding in the stomachs of these monsters.

From the surface, Gray's Reef National Marine Sanctuary might not look too different from the rest of the ocean -- but beneath the waves, you'll find a vibrant reefscape. Find out what makes this Georgia reef so special, and how researchers work to better understand the ecosystem.

The sea, the world ocean or simply the ocean is the connected body of salty water that covers over 70 percent of the Earth's surface. It moderates the Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. It has been travelled and explored since ancient times, while the scientific study of the sea—oceanography—dates broadly from the voyages of Captain James Cook to explore the Pacific Ocean between 1768 and 1779. The word "sea" is also used to denote smaller, partly landlocked sections of the ocean. The most abundant solid dissolved in sea water is sodium chloride. The water also contains salts of magnesium, calcium, and potassium, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however the relative proportions of dissolved salts varies little across the oceans. Winds blowing over the surface of the sea produce waves, which break when they enter shallow water. Winds also create surface currents through friction, setting up slow but stable circulations of water throughout the oceans. The directions of the circulation are governed by factors including the shapes of the continents and the rotation of the earth (the Coriolis effect). Deep-sea currents, known as the global conveyor belt, carry cold water from near the poles to every ocean. Tides, the generally twice-daily rise and fall of sea levels, are caused by the rotation of the Earth and the gravitational effects of the orbiting Moon, and to a lesser extent of the Sun. Tides may have a very high range in bays or estuaries. Submarine earthquakes arising from tectonic plate movements under the oceans can lead to destructive tsunamis, as can volcanoes, huge landslides or the impact of large meteorites. A wide variety of organisms, including bacteria, protists, algae, plants, fungi and animals, live in the sea, which offers a wide range of marine habitats and ecosystems, ranging vertically from the sunlit surface waters and the shoreline to the enormous depths and pressures of the cold, dark abyssal zone, and in latitude from the cold waters under the Arctic ice to the colourful diversity of coral reefs in tropical regions. Many of the major groups of organisms evolved in the sea and life may have started there. The sea provides substantial supplies of food for humans, mainly fish, but also shellfish, mammals and seaweed, whether caught by fishermen or farmed underwater. Other human uses of the sea include trade, travel, mineral extraction, power generation, warfare, and leisure activities such as swimming, sailing and scuba diving. Many of these activities create marine pollution. The sea is important in human culture, with major appearances in literature at least since Homer's Odyssey, in marine art, in cinema, in theatre and in classical music. Symbolically, the sea appears as monsters such as Scylla in mythology and represents the unconscious mind in dream interpretation.

The threats to tropical fish like blue tangs are a REAL problem. Conservation organizations like SeaWorld are finding AMAZING solutions.
