Strombidium lagenula is a species of marine planktonic ciliates belonging to the genus Strombidium (which contains about 31 species) in the order Oligotrichida.Like other ciliates, they are unicellular eukaryotes that move using cilia.
Salps are common in equatorial, temperate, and cold seas, where they can be seen at the surface, singly or in long, stringy colonies.The most abundant concentrations of salps are in the Southern Ocean [4] (near Antarctica), where they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill.

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. Zooplankton can also act as a disease reservoir.
Towing line and bridle The towing line and bridle is the upper part of a plankton net and used to hold it. The towing lines connected to the triangle bridles are made of nylon rope and can be adjust to a level suitable for the user.
In cooler climates including the North Atlantic, it is frequently the dominant zooplankton in the spring and summer. Acartia tonsa produces eggs in the winter in colder geographic regions. The eggs hatch when temperatures exceed 15 °C (59 °F). [7] [8] They are an important food source for many commercial fish species. [8]
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.
Mesopelagic zooplankton have unique adaptations for the low light. Bioluminescence is a very common strategy in many zooplankton. This light production is thought to function as a form of communication between conspecifics, prey attraction, prey deterrence, and/or reproduction strategy. [8]
Ichthyoplankton (from Greek: ἰχθύς, ikhthus, "fish"; and πλαγκτός, planktos, "drifter" [1]) are the eggs and larvae of fish. They are mostly found in the sunlit zone of the water column, less than 200 metres deep, which is sometimes called the epipelagic or photic zone.
