Proportions of the jaw mechanism of cichlid fishes changes and their meaning

Acta Biotheoretica, 1985
The jaw mechanism of cichlid fishes is an intricate apparatus with complex force transmission from muscles to environment. The proportions of this apparatus change considerably during growth mainly due to scale effects. In adult fishes, the proportions differ, corresponding with the type of preferred food.

Mechanisms of the jaws of some atheriniform fish

Journal of Zoology, 1967
The Atheriniformes is an order of teleost fish which consists of the Atherinoidei (sand smelts etc.), Cyprinodontoidei (tooth‐carps) and Exocoetoidei (halfbeaks etc.). Some of its members have protrusible upper jaws and some do not. Photographs have been taken of two species of Cyprinodontoidei feeding, to discover how they use their jaws, which are ...

Evolution of complexity in motor patterns and jaw musculature of tetraodontiform fishes

Journal of Experimental Biology, 1999
ABSTRACT The prey-processing behavior and jaw-adducting musculature of tetraodontiform fishes provide a novel system for studying the evolution of muscles and their function. The history of this clade has involved a pattern of repeated ‘duplications’ of jaw muscles by physical subdivision of pre-existing muscles.

The pharyngeal jaw apparatus of labrid fishes: A functional morphological perspective

Journal of Morphology, 1986
AbstractAmong the acanthopterygian fishes, the Labridae possess the most highly integrated and specialized pharyngeal jaw apparatus. The integrated feature involves many osteological components and aspects of muscle form, architecture, composition, and function. The upper jaw articulates by means of a true diarthrosis with the pharyngeal process of the

On Relative Growth in the Jaws of Certain Fishes.

Proceedings of the Zoological Society of London, 1935
Summary. 1 In Lepidosteus osseus growth of the jaws relative to the rest of the body is of the type termed heterogonic. 2 There are two quite distinct periods in this growth, both showing heterogony, the growth coefficient being much higher over the first than over the second period. 3 The growth of the jaws relative to the rest of the body

Anatomical and Physiological Peculiarities of the Heart in Jawless and Jawed Fish

Journal of Evolutionary Biochemistry and Physiology, 2021
The heart of jawless fish (Cyclostomata; lamprey, hagfish) and jawed fish (Teleostei) is homologous to the heart of higher vertebrates. A study of this organ in archaic Cyclostomata and Teleostei, which are different in their evolutionary “ages”, genetic characteristics and hypoxia tolerance, is of particular interest in the search for the factors that

[Jaws of fish 1].

Clinical calcium, 2005
A group of fish is not a mophyletic and includes some different classification groups. Fish are the popular name of animals which has the shape of fish. Most of fish bear jaw, but some fish do not have jaws. Formation of jaw is an important event in the history of early vertebrates. Jaws are originated from visceral arches.

Jaws: The Inside Story. The Metabolism of Elasmobranch Fishes

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
Abstract Elasmobranchs are of metabolic interest for several reasons, including their primitive evolutionary position, their osmotic strategy and their low incidence of neoplasia. Some aspects of the metabolism of elasmobranch fishes are unique when compared with those of the other vertebrates.

[Jaws of fish 2].

Clinical calcium, 2005
Structure of Jaws in fish composed of mandibular and hyoid arches. Hyomandibular which is upper part of hyoid arch plays an important role of jaw suspension. Various jaw structures are developed in fish. One of the samples is protrusible upper jaw in cyprinid fish.

Evolution of the upper jaw mechanism in teleost fishes

Journal of Morphology, 1935
AbstractThis study reveals the existence of four distinct but genetically related types of upper jaw mechanisms:1. The non‐protractile, with no mechanism for the protrusion of the pre‐maxillae. The maxillaries form part of the upper margin of the mouth, as in Isospondyli, Apodes and Haplomi.2.
