Bosmina longirostris is a species of water flea found in the Great Lakes and Central Europe. It is found in the plankton near the shoreline of lakes and ponds. [2]
Many zooplankton are tiny animals found with the phytoplankton in oceanic surface waters, and include tiny crustaceans, and fish larvae and fry (recently hatched fish). Most zooplankton are filter feeders, and they use appendages to strain the phytoplankton in the water. Some larger zooplankton also feed on smaller zooplankton.
Zooplankton feed on bacterioplankton, phytoplankton, other zooplankton (sometimes cannibalistically), detritus (or marine snow) and even nektonic organisms. As a result, zooplankton are primarily found in surface waters where food resources (phytoplankton or other zooplankton) are abundant.
Coregonus zugensis, also known as the Swiss whitefish, is a freshwater species of fish of the subfamily Coregoninae which is found in Europe lakes of Lucerne and Zug. [2] However, in a recent study, it was found that the species had been extirpated from Lake Zug.
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
Coregonus albula, known as the vendace or as the European cisco, [1] is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Latvia, [ 2 ] Lithuania, Sweden, Russia and Estonia, and in some lakes of Norway, the United Kingdom, northern Germany, and Poland.
[3] [7] Lakes are divided into photic and aphotic regions, the prior receiving sunlight and latter being below the depths of light penetration, making it void of photosynthetic capacity. [2] In relation to lake zonation, the pelagic and benthic zones are considered to lie within the photic region, while the profundal zone is in the aphotic ...
The global biomass of gelatinous zooplankton (sometimes referred to as jelly‐C) within the upper 200 m of the ocean amounts to 0.038 Pg C. [21] Calculations for mesozooplankton (200 μm to 2 cm) suggest about 0.20 Pg C. [22] The short life span of most gelatinous zooplankton, from weeks up to 2 to 12 months, [23] [24] suggests biomass ...
