Cyclops bicuspidatus is a planktonic species of copepod found throughout the world, except Australia, [4] and characteristic of the Great Lakes of North America. [5] It is a deep water species found throughout the year with peak abundance occurring in May or June. [5]
Normally they travel in large groups, which tends to result in huge swaths of them consuming all of the zooplankton in the area. This leads to detrimental impacts for the local ecosystem in which they travel through. Since they eat all the zooplankton, there is a lack of food for the other species relying on the plankton as their food source. [6]
Calanoid copepods are the dominant animals in the plankton in many parts of the world's oceans, making up 55–95% of plankton samples. [2] They are therefore important in many food webs, taking in energy from phytoplankton and algae and 'repackaging' it for consumption by higher trophic level predators. [ 2 ]
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.
They are found as zooplankton throughout the global ocean. As zooplankton, radiolarians are primarily heterotrophic, but many have photosynthetic endosymbionts and are, therefore, considered mixotrophs. The skeletal remains of some types of radiolarians make up a large part of the cover of the ocean floor as siliceous ooze.
Micronekton typically ranges in size from 2 to 20 cm, macro-zooplankton from 2 mm to 2 cm, meso-zooplankton from 0.2 to 2 mm and micro-zooplankton from 20 μm to 0.2 mm. Micronekton represents 3.8-11.8 billion tons of mesopelagic fishes worldwide, [3] [4] approximately 380 million tons of Antarctic krill in the Southern Ocean [5] and a global ...
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 ...
Bacterioplankton refers to the bacterial component of the plankton that drifts in the water column.The name comes from the Ancient Greek word πλαγκτός (planktós), meaning "wandering" or "drifting", and bacterium, a Latin term coined in the 19th century by Christian Gottfried Ehrenberg.
