Fluid feeders are organisms that feed on the fluid of other organisms. It can refer to: Hematophagy, feeding on blood; Nectarivore, feeding on nectar; Plant sap feeders
The motion of the head may induce a bow wave in the fluid which pushes the prey away from the jaws, but this can be avoided by allowing water to flow through the jaw. This can be accomplished by means of a swept-back mouth, as in balaenid whales, [ 21 ] or by allowing water to flow out through the gills, as in sharks and herring .

Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
For example, hummingbirds and hawkmoths have long narrow beaks that can reach nectar at the bottom of long tubular flowers. [4] [5] The majority of nectar feeders are insects or birds, but instances can also be found in other animal groups.
In 2021, some research suggested Protomelission, a genus known from the Cambrian period, could be an example of an early bryozoan, [17] but later research suggested that this taxon may instead represent a dasyclad alga. [3] Early fossils are mainly of erect forms, but encrusting forms gradually became dominant.

The fluid in the coelomata contains coelomocyte cells that defend the animals against parasites and infections. In some species coelomocytes may also contain a respiratory pigment – red hemoglobin in some species, green chlorocruorin in others (dissolved in the plasma) [ 23 ] – and provide oxygen transport within their segments.
