Copepods are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic, some are benthic, a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, puddles, damp moss, or water-filled recesses of plants (phytotelmata) such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators.
The European sprat, also known as bristling, brisling, garvie, garvock, Russian sardine, russlet, skipper or whitebait, is a species of small marine fish in the herring family Clupeidae. Found in European waters, it has silver grey scales and white-grey flesh. Specific seas in which the species occurs include the Irish Sea, Black Sea, Baltic Sea and Sea of the Hebrides. The fish is the subject of fisheries, particularly in Scandinavia, and is made into fish meal, as well as being used for human consumption. When used for food it can be canned, salted, breaded, fried, boiled, grilled, baked, deep fried, marinated, broiled, and smoked.
Wilhelm Giesbrecht (1854–1913) was a Prussian zoologist, specialising in copepods, during the "golden age of copepodology".

Temora longicornis is a species of copepod in the family Temoridae. It is found in marine environments on both sides of the Atlantic Ocean.
Temora stylifera is a copepod primarily found in the Atlantic and surrounding waters.
Temora turbinata is a copepod in the Temoridae family. It is an epipelagic species, having been recorded in coastal waters around the world. It was first described in 1849 by American scientist James Dwight Dana.
Temora discaudata is a copepod in the family Temoridae. It was first described in 1849 by James Dwight Dana, being placed in the Calanus genus. It was described as a member of the Temora genus in 1889 by Prussian zoologist Wilhelm Giesbrecht. The female measures between 1.68 mm to 2.05 mm in length, while the male ranges between 1.65 and 1.85 mm. It is found in the Pacific, Indian, and (marginally) Atlantic Oceans.
