Ctenophora predation by ctenophores may control the populations of small zooplanktonic organisms such as copepods, which might otherwise wipe out the phytoplankton (planktonic plants), which are a vital part of marine food chains. Almost all ctenophores are predators – there are no vegetarians and only one genus that is partly parasitic. If food is plentiful, they can eat 10 times their own weight per day. While "Beroe" preys mainly on other ctenophores, other surface-water species prey on zooplankton (planktonic animals) ranging in size from the microscopic, including mollusc and fish larvae, to small adult crustaceans such as copepods, amphipods, and even
National Institute of Allergy and Infectious Diseases government, and non-governmental organizations in multifaceted and multidisciplinary efforts to address emerging health challenges such as the pandemic H1N1/09 virus. NIAID traces its origins to a small laboratory established in 1887 at the Marine Hospital on Staten Island, New York Officials of the Marine Hospital Service in New York decided to open a research laboratory to study the link between microscopic organisms and infectious diseases. Dr. Joseph J. Kinyoun, a medical officer with the Marine Hospital Service, was selected to create this laboratory, which he called a "laboratory of hygiene." Kinyoun's lab was renamed the Hygienic Laboratory in 1891 and
