Multiple Osteochondromas (MO; previously known as multiple hereditary exostosis) is an autosomal dominant genetic condition that is characterized by the formation of cartilaginous bone tumours (osteochondromas) at multiple sites in the skeleton, secondary bursa formation and impingement of nerves, tendons and vessels, bone curving, and short stature. MO is also known to be associated with arthr...

The paper provides information on the biological parameters and feeding of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) that has entered Krasnoyarsk Reservoir by escaping from fish farm cages. In diet studied individuals, eleven groups food components are found; imagoes terrestrial insects chironomid larvae dominate in ration. At same time, individuals characterized slow linear weight grow...

According to the modern fish system, one species of fourhorn sculpin Triglopsis quadricornis lives in Baltic Sea and Arctic waters. In present study, sculpins from White Seas were studied using different methods: morphological analysis establish patterns seismosensory tomography for study cranial bones, X-ray imaging axial skeleton, as well phylogenetic two mtDNA markers (control region CO1) nD...

Kelp bass (Paralabrax clathratus) and leopard sharks (Triakis semifasciata) are characterized by an acellular (anosteocytic) bony skeleton and a focally calcified cartilaginous endoskeleton, respectively. These skeletal forms are not considered to function as mineral reservoirs. Previous studies showed that implanted bone particles are resorbed in rats by large multinucleated cells with ultrast...

The rich phenotypic diversity that characterizes the vertebrate skeleton results from evolutionary changes in regulation of genes that drive development. Although relatively little is known about the genes that underlie the skeletal variation among fish species, significant knowledge of genetics and development is available for zebrafish. Because developmental processes are highly conserved, th...

Highlight Research The endolithic bioeroders were identified. Cocconeis sp. was new for the science of euendolithic bioeroder Scleractinian coral. SEM revealed etch and bore coral skeleton. Pennate diatom present on cavities. Abstract Laminar coral, Montipora, contributes to reef ecosystem. laminar life form is usually used by juvenile biota shelter prey. In an intertidal area, such as Pantai K...

In teleost fish, as in other vertebrates, calcium is of key importance for numerous physiological processes. The skeleton of vertebrates consists mainly of calcium phosphate and calcium carbonate. It serves an important role as it determines body shape, protective aspects (scales, bone plates) and as a buffer internal reservoir for calcium and phosphorus. In teleosts, ~99% of the whole-body cal...

Elasmobranchs (e.g. sharks and rays), like all fishes, grow continuously throughout life. Unlike other vertebrates, their skeletons are primarily cartilaginous, comprising a hyaline cartilage-like core, stiffened by a thin outer array of mineralized, abutting and interconnected tiles called tesserae. Tesserae bear active mineralization fronts at all margins and the tesseral layer is thin enough...

1187 Coral reefs, among Earth’s richest ecosystems, traditionally teem with an abundance of life. The tiny corals that form the foundation of the community are microcosms themselves, sheltering single-celled algae that feed the community with energy from the sun. The three-dimensional physical space they create with their skeletons supports an astounding array of other animals, from sponges to ...
