Causes of Abdominal Pain in Children. Infections: Viruses or bacteria can cause abdominal pain, typically from stomach flu or gut flu (called gastroenteritis). Viral infections tend to go away quickly, while bacterial infections may need an antibiotic to get better.
Brain corals, a slow-growing species of coral, often act as foundations for reefs. Brain coral in the Dry Tortugas, Florida. The cerebral-looking organisms known as brain corals do not have brains, but they can grow six feet tall and live for up to 900 years! Found in the Caribbean, Atlantic, and Pacific Oceans, brain corals display what is known as Meandroid tissue integration. This means that the polyps, which are the basic living unit of corals, are highly associated to one another.
Pacific Kelp Forest Urchins. Photo by Paul Banko. This lovely photograph shows the three common urchins found in eastern Pacific kelp forests. Red = Strongylocentrotus franciscanus; Purple = Strongylocentrotus purpuratus; White = Strongylocentrotus droebachiensis.ereocystis luetkeana often dominates northeastern Pacific kelp forests. It has a long stipe that is attached often to a small rock and is kept aloft by a gas-filled float. The fronds extend from the float. This makes for a very unstable arrangement and strong storms often uproot the plant.
