Fish fillets comprise the flesh of the fish, which is the skeletal muscles and fat as opposed to the bones and organs. Fillets are usually obtained by slicing the fish parallel to the spine, rather than perpendicular to the spine as is the case with steaks. The remaining bones with the attached flesh is called the "frame", and is often used to ...
Fish anatomy. Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. [1] In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or ...
Fish physiology is the scientific study of how the component parts of fish function together in the living fish.

Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments. These filaments have many functions including ...
Gill raker. Gill rakers in fish are bony or cartilaginous processes that project from the branchial arch (gill arch) and are involved with suspension feeding tiny prey. They are not to be confused with the gill filaments that compose the fleshy part of the gill used for gas exchange. Rakers are usually present in two rows, projecting from both ...
Pseudobranch. The pseudobranch, also pseudobranchia, is the reduced first gill arch of a fish (on the inner surface of the opercle, near the junction of the preopercle) as well as a reduced "false" gill in some gastropods . In teleost fish, the pseudobranchs are mostly without respiratory function, and in elasmobranchs they are the gill arch of ...
Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
Aggressive panhandling is a legal term for unlawful forms of public begging. Proponents of such legislation advocate placing limits on these activities. Some opponents believe statutes prohibiting aggressive panhandling are part of the "criminalization of homelessness" and argue that such laws are discriminatory or unevenly enforced.
