We currently have videos and information on 14 Cartilaginous fish.

The following habitats are found across the Cartilaginous fish distribution range.

These odd, often translucent cartilaginous fish are typically quite small.

Sharks and rays can be heavier, but they're cartilaginous fish.

Cartilaginous fish, such as sharks also lack a true maxilla.

A similar, but probably non-homologous, structure is found in cartilaginous fishes.

Cartilaginous fishes first appeared by about 395 million years ago, in the middle Devonian.

This is the system currently found in cartilaginous fishes.

Cartilaginous fish (sharks and rays) have a more advanced immune system.

Sturgeons are among the largest and most ancient of cartilaginous fishes.

As in cartilaginous fish, the upper part of the duct forms the epididymis.

During the Carboniferous the state was home to an unusual cartilaginous fish fauna.

At that time, the state was home to a bewildering array of cartilaginous fishes.

This is the first confirmed case of hybridization among cartilaginous fishes.

The skin of most bony and cartilaginous fishes is covered by scales.

Eagle rays are cartilaginous fish in the ray family Myliobatidae.

P53 diverged from p63/p73 with a gene duplication in the cartilaginous fish.

IgD was recently found to be present in species from cartilaginous fish to human (probably with the exception of birds).

Cartilaginous fish, such as sharks, have also simple, and presumably primitive, skull structures.

Harriotta is a genus of cartilaginous fish in the Rhinochimaeridae family.

Stingrays are a family of cartilaginous fish containing nine genera and about 70 species.

A Sawfish is a large, endangered cartilaginous fish with a saw-shaped nose.

Placoid scales are found on cartilaginous fish including sharks.

A stingray is a type of cartilaginous fish.

The cartilaginous fish are so named because their skeleton is composed of cartilage...

There is no parental care after birth; however, some Chondrichthyes do guard their eggs.

All Chondrichthyes breathe through 5-7 gills, depending on the species.

They are chondrichthyes, and closely related to the rays.

It belongs to the subclass Elasmobranchii in the class Chondrichthyes.

Like other members of the class Chondrichthyes, chimaeras have a skeleton constructed of cartilage.

Sharks and other chondrichthyes have placoid scales made of denticles, like small versions of their teeth.

Sharks are in a class of fish called Chondrichthyes, with skeletons made of cartilage instead of bone.

Elasmobranchii, or Chondrichthyes, sharks, skates and rays, and chimaeras.

Chondrichthyes have toothlike scales called dermal denticles or placoid scales.

Angel sharks have historically been heavily fished but education has played a role in reducing overfishing of these slow-reproducing chondrichthyes.

In fact, the three traditional classes of fish (Agnatha, Chondrichthyes and Osteichthyes) all represent evolutionary grades.

Chondrichthyes also lack ribs, so if they leave water, the larger species' own body weight would crush their internal organs long before they would suffocate.

Neoselachii are a grouping of fishes in subclass Elasmobranchii of class Chondrichthyes.

Chondrichthyes (cartilaginous fish; 300+ species)

Elasmobranchii is a subclass of Chondrichthyes or cartilaginous fish, that includes the sharks and the rays and skates.

Cartilaginous fishes, class Chondrichthyes, consisting of sharks, rays and chimaeras, appeared by about 395 million years ago, in the middle Devonian.

Chondrichthyes (Cartilagenous Fish)

The spiracles typical of Chondrichthyes are vestigial, and mantas must swim continuously to keep oxygenated water passing over their gills.

Unlike true sharks, which belong to the Chondrichthyes ("cartilagenous fishes") lineage, the rainbow shark is an actinopterygiian ("ray-finned fish").

Even after the evolution of the vertebral column in chondrichthyes and osteichthyes, these taxa remained common and are well represented in the fossils record.

In chondrichthyes the cranial nerves run from the part of the brain that interprets sensory information, and radiate out towards the organs that produce those sensations.

They may have been an independent phylogenetic branch of fishes, which had evolved from generalized or basal forms similar to primitive members of the still-extant Chondrichthyes.

Chondrichthyes or cartilaginous fishes are jawed fish with paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage rather than bone.

Like most other chimaeriformes, Edaphodon is known mainly from poorly preserved specimens; this is due to Edaphodon belongs to Chondrichthyes class, whose sceleton is made of cartilage.

In some classifications the chimaeras are included (as subclass Holocephali) in the class Chondrichthyes of cartilaginous fishes; in other systems this distinction may be raised to the level of class.
