Cyprinids are stomachless, or agastric, fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used ...
During the compression phase, the jaws close and water is compressed out of the gills. Though suction feeding can be seen across fish species, those with more cranial kinesis show an increase in suction potential as a result of more complex skull linkages that allow greater expansion of the buccal cavity and thereby create a greater negative ...
The mouth opens into a characteristic chewing pharynx ... For this reason, they are used in fish tanks to help clean the water, to prevent clouds of waste matter ...

The red garra (Garra rufa), also known as the doctor fish or nibble fish, is a species of cyprinid that is native to a wide range of freshwater habitats in subtropical parts of Western Asia. [4] This small fish typically is up to about 14 centimeters (5.5 inches) in total length, [ 4 ] but locally individuals can reach as much as 24 cm (9.5 in).
The skipjack herring (Alosa chrysochloris) is a North American, migratory, fresh- and brackish water fish species in the herring family Alosidae. [3] The name skipjack shad comes from the fact that it is commonly seen leaping out of the water while feeding. [4]
Raw fish should be frozen to an internal temperature of −20 °C (−4 °F) for at least 7 days to kill parasites; home freezers may not be cold enough. [47] [48] Historically, fish that live all or part of their lives in fresh water were considered unsuitable for sashimi due to the possibility of parasites (see Sashimi article).
Ram ventilation [11] is the process in which at higher speeds, the remora uses the force of the water moving past it to create movement of fluid in the gills. At lower speeds, the remora will use a form of active ventilation, [11] in which the fish actively moves fluid through its gills. In order to use active ventilation, a fish must actively ...
