The ultrastructure of the otolithic membrane and otolith in the juvenile mummichog, Fundulus heteroclitus
TLDR
Evidence is presented which suggests that the fibrous material of the subcupular meshwork is incorporated into the otolith as an organic matrix constituent. Expand
Studies on fish scale formation and resorption—II. Effect of estradiol on calcium homeostasis and skeletal tissue resorption in the goldfish, Carassius auratus, and the killifish, Fundulus
TLDR
Skeletal tissue resorption was examined by estradiol injection in 45Ca-prelabeled fish, Carassius auratus and Fundulus heteroclitus and no evidence was obtained in favor of Ca resOrption from the vertebra, jaw and otolith. Expand
Studies on fish scale formation and resorption
SummaryElectron microscopic investigation of scales of the goldfish Carassius auratus revealed that the lamellae of fibrillary plates contain sheet-like structures composed of vertically orientedExpand
The organic matrices of the shell of the American oyster Crassostrea virginica Gmelin
TLDR
Soluble and insoluble matrices appear to be synthesized separately, but packaged into the mucous droplets of the outer shell-side epithelium of the mantle, where they aggregate in groups and are secreted into the extrapallial cavities. Expand

  • 1 April 1961
Details of crystal growth in the calcitostracum of Crassostrea virginica have been studied with the purpose of analyzing the formation of the overlapping rows of oriented tabular crystalsExpand
Temporal and metal-specific patterns in the accumulation of heavy metals by the scales of Fundulus heteroclitus
TLDR
The results indicate that teleost scales may be useful as continuous recorders of environmental metal exposure: the elemental composition of each circulus reflecting that of the environment at the time the circulus formed. Expand
Studies on reef corals. I. Skeleton formation by newly settled planula larva of Pocillopora damicornis
TLDR
The basal disc with its septal rudiments constitutes a true larval skeleton, differing in morphology, micro-architecture, and crystal type from the fibrous growth characterizing the adult skeleton. Expand
STUDIES ON SHELL FORMATION. XI. CRYSTAL-MATRIX RELATIONSHIPS IN THE INNER LAYERS OF MOLLUSK SHELLS.
  • N. Watabe
  • Biology, Medicine
  • Journal of ultrastructure research
  • 1 April 1965
The relationships of crystals to the organic matrix in which they form have been studied in the shell of three bivalve mollusks, Pinctada martensii, Elliptio complanatus, and Crassostrea virginica,Expand
Scanning electron microscope observations of the organic matrix in the otolith of the teleost fish Fundulus heteroclitus (Linnaeus) and Tilapia nilotica (Linnaeus)
TLDR
Scanning electron microscope observations of sagitta otoliths of Fundulus heteroclitus and Tilapia nilotica have revealed that the “discontinuous zone” is a narrow band of organic matrix consisting of fibers that are composed of thin fibers ≈200 A thick, and a possible process of otolith formation is proposed.
