Feeding in Cartilaginous Fishes: An Interdisciplinary Synthesis
2019Fishes, and elasmobranchs in particular, are often described as “opportunistic” predators meaning that they will take advantage of feeding opportunities as they arise. The implication of this term is that elasmobranchs are not selective about what they eat, which is a gross oversimplification of the complex interactions that shape diet, many of which ...

The Telencephalon of Cartilaginous Fishes
1990The fishes are the largest group of vertebrates. Two subdivisions can be recognized: the Osteichthyes or bony fishes including about 25,000 species, and the Chondrichthyes or cartilaginous fishes comprising only about 800 species. The latter is separated from the former by several features but the most distinctive is their cartilaginous endoskeleton.

1999
In this chapter, I summarize the little we know about the neural crest in bony and cartilaginous fishes. This does not imply that fish form a natural group of vertebrates or that the various groups of fishes are more closely related to one another than to other vertebrates. The studies available are primarily on teleost fishes and elasmobranchs (sharks,

First report on leptin in a cartilaginous fish
2010Leptin is a hormone involved in food intake. It is conserved through evolution, but no studies that have focused on its presence in cartilaginous fish are available to date. Here we report the presence of leptin-like immunoreactivity in the gut of the cartilaginous fish Scyliorhinus canicula (Linnaeus,1758) using Western Blot and immunohistochemical ...

MHC Molecules of Cartilaginous Fishes
2014The major histocompatibility complex (MHC) is a deoxyribonucleic acid (DNA) region that contains genes involved in antigen processing and presentation, though not exclusively. Evidence for MHC genes has been found in all jawed vertebrates studied, but not in jawless fish or invertebrates. Orthologous genes for the antigen presentation proteins, namely,

Status of Cartilaginous Fishes in Pakistan
SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES, 2018Pakistani fishermen are involved in shark fishing activity and caught cartilaginous fishes as by catch by using gillnet despite their population is decline. In this study we recorded small and large size sharks were found at the two major fish landing sites i.e. Karachi fish harbor and Korangi fish harbor ranging from (29-188cm), rays (DL: 21-104cm and
