Acartia tonsa is a calanoid copepod species that can be found in a large portion of the world's estuaries and areas of upwelling where food concentrations are high. They commonly have shortened bodies, with a smaller abdomen that normally doesn’t have appendages. Acartia tonsa are translucent copepod species that can be found in most of the worlds estuaries and coastal waters. A. tonsa has a translucent body that ranges from 0.5 mm to 1.5 mm in length. Tiselius et al., 1995, 2008) and also it has been used as food for suspension-feeding organisms in laboratory experiments and for fish larvae in aquaculture (Holmstrup et al., 2006) as well as for toxicity-tests (Nielsen et al., 1990; Kusk & Petersen, 1… 95842).Members of the subclass Copepoda are gonochoric and sexually dimorphic. 22 May 2016. … Acartia tonsa’s success and abundance may also be attributed to its tolerance of a wide range of ocean temperatures (-1 to 32ºC) and salinities (1 ppt to 38 ppt), helping it compete in a variety of estuarine microclimates. Acartia tonsa; Local Common Names. Also commonly known as Cyclops. akarcja tonza in Polish.

They also play an important role in the mixing and cycling of nutrients and energy in marine ecosystems, forming a trophodynamic link connecting primary (phytoplankton) and tertiary (e.g., planktivorous fish) production, and are considered a keystone species.
