Cartilage
A firm, flexible connective tissue. In vertebrates, the cartilage forms the skeleton in the early stages of development, after which it is largely replaced by bone. Some cartilage remains at the joints to give flexibility and support.
· Cartilage = gristle
· Cartilaginous = the one with skeleton consisted from cartilages and not bones (see also Chondrichthys)
· Carnivorus (pl. carnivores) = organisms feeding on animal matter, from latin word carna (possessive case carnae) ...
First symptoms usually emerge after 12 days, the fish now suffering from lesions in the sensitive cartilage cavity surrounding the nervous system and brain cavity.
An octopus can get out a hole 1/4 the width of its mantle since the only hard part is cartilage surrounding its brain - if it can get an arm through the rest will follow. (2) they are voracious eaters and usually will only eat live food.
Beloniformes: Interarcual cartilage (connects the epibranchial bone of the first gill arch with the infrapharyngobranchial of the second gill arch) small or absent; small second and third epibranchials; interhyal absent; ...
Their skeleton is composed of bone and cartilage, yet they also have certain features that are more characteristic of modern bony fishes like concaved vertebrae, thin bony plates on the head, and a rounded tail.
The prescence of a particular bone structure in the lower jaw (which is cartilage in other cichlids) has been used as a major character to distinguish genera which belong to a group defined as the "ossified group".
Gill arch
one of the bony (or cartilage) arches or curved bars extending dorsoventrally (out the side) and placed one behind another on each side
of the pharynx (throat) and supporting the gills.
Ascorbic Acid (C)
Functions: - enzyme systems, bone, tooth and cartilage formation and healing
Deficiencies: - hemorrhagic shin, kidneys, liver, intestine and muscle tissue, eye lesions and scoliosis of the spine ...
Vitamin C (ascorbic acid) in fishes is directly related to the formation of procollagen fibers necessary for the biosynthesis of collagen and cartilage, tissue formation and repair and calcification of bone.
