The Immune System of Cartilaginous Fish

2000
Chondrichthyes, or cartilaginous fish, are a highly successful group of vertebrates. Most extant species are long-lived, display an amazing diversity, and fill all predatory oceanic niches (and a few other niches as well; Wilson 1992). For our purposes, they are the oldest group of vertebrates shown to possess an adaptive immune system grounded on ...

Antibody repertoire development in cartilaginous fish

Developmental & Comparative Immunology, 2006
There are 3 H chain and 3 L chain isotypes in the cartilaginous fish, all encoded by genes in the so-called cluster (VDDJ, VJ) organization. The H chain isotypes IgM and IgNAR, are readily detected at the protein level in most species. The third is readily identified at the protein level in skates (IgR) but only via immunoprecipitation or at the ...

Cartilaginous Fish Skeletal Anatomy ☆

2017
Most adult vertebrate animals have bony skeletons, with cartilage mostly restricted to joints and flexible structures. In contrast, the Chondrichthyes (sharks, batoids, and chimaeras) have endoskeletons made entirely of cartilage. Moreover, in sharks and batoids, most of the skeletal cartilage is tessellated, covered with mineralized, subperichondral ...

Angiotensin and angiotensin receptors in cartilaginous fishes

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2001
In mammals, a principal bioactive component of the renin-angiotensin system (RAS), angiotensin II (ANG II), is known to be vasopressor, dipsogenic, a stimulant of adrenocortical secretion and to control glomerular and renal tubular function. Historically, a RAS analogous to that found in mammals was thought to have first evolved in the bony fishes ...

Cartilaginous fishes (Chondrichthyes)

2009
Abstract Living members of the Subclasses Holocephali (chimaeras, including ratAshes, spookAshes, and rabbitAshes, 43 sp.) and Elasmobranchii (sharks, rays, skates, sawAshes, and guitarAshes, 1125 sp.) together comprise the extant representatives of the Class Chondrichthyes (cartilaginous Ashes) (1).

Complement system of bony and cartilaginous fish

Fish & Shellfish Immunology, 2000
Accumulating evidence indicates that the complement system experienced a discontinuous development at an early stage of vertebrate evolution. Invertebrates such as echinoderms and ascidians, and the most primitive extant vertebrates, the cyclostomes, seem to have a primitive complement system equipped only with the alternative and lectin pathways.

The Cartilaginous Fish

1996
The cartilaginous fish probably evolved about the same time as or just before the bony fish some 300 MYA during the great growth burst of animal and vegetable life on this planet. Chondrichthyes have skeletons composed entirely of cartilage and movable lower jaws usually with teeth. They are divided into two subclasses:

THE SKELETON | Cartilaginous Fish Skeletal Anatomy

2011
Although the clades of cartilaginous fishes can be broadly considered to share a generalized skeletal body plan comprised of the same elements, their skeletons exhibit clade-specific arrangements and morphologies. © 2011 Elsevier Inc. All rights reserved.
