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 ...

Molecular phylogenetics of gnathostomous (jawed) fishes: old bones, new cartilage

Zoologica Scripta, 2001
Cartilaginous fishes (chondrichthyans) have traditionally been taken as an early offshoot among jawed vertebrates. To examine some crucial chondrichthyan relationships, we have sequenced the mitochondrial genomes of the holocephalanChimaera monstrosa(ratfish) and the basal galeomorph speciesHeterodontus francisci(horn shark) and analysed them together ...

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.

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.

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

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.
