What are the similarities and differences between the bony and cartilaginous fish?

Technically, the most obvious disparity between bony vs cartilaginous fish comes from the fact that the skeleton of bony fish is made of bones alone, while that of cartilaginous fish is made of cartilage. There are more than 20,000 fish species in the world.

What do cartilaginous and bony fishes have in common?

As the name suggests, “bony fish” have a skeleton composed of only bones while a cartilaginous fish has a skeleton made entirely of cartilage….

What are fishes similarities and differences?

All fish share two traits: they live in water and they have a backbone—they are vertebrates. Apart from these similarities, however, many of the species in this group differ markedly from one another. Fin fish like salmon have gills, are covered in scales, and reproduce by laying eggs.

What are the characteristics of cartilaginous fish?

Other characteristics of cartilaginous fish include:

  • Paired fins.
  • Paired nostrils.
  • Scales.
  • Two-chambered hearts.
  • Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone.

What are three characteristics of chondrichthyes?

Species in this class have paired fins, hard scales, a two-chambered heart, and a pair of nostrils. Most species have 5-7 gill slits on each side of their body. Some species produce egg cases, others give birth to live young.

What are the main characteristics of osteichthyes?

Class – Osteichthyes Bony fishes share several distinguishing features: a skeleton of bone, scales, paired fins, one pair of gill openings, jaws, and paired nostrils. Osteichthyes includes the largest number of living species of all scientific classes of vertebrates, more than 28,000 species.

What are 4 characteristics that all cartilaginous fish have in common?

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

What is the similarities of fish?

Fish are obviously animals because they move, they have sensory organs (eyes, mouth, barbels), and they have body structure (skeletons, skin, etc.). They breathe oxygen. They eat other organisms to survive. Fish are different from other animals because they live in water.

What are the similarities between fish and frog?

Both frogs and fish belong to the phylum Chordata and the subphylum Vertebrata. This means that both frogs and fish have a spinal cord and backbone. In addition, all chordates have bilateral symmetry. This means that they have a matching left and right side.

What are the main characteristics of chondrichthyes?

Key Features of Chondrichthyes

  • Resemble bony fish and terrestrial vertebrates in having jaws and paired appendages.
  • An electroreceptive system is well developed.
  • Endoskeleton entirely cartilaginous.
  • No swim bladder or lung.

What’s the difference between Osteichthyes and Chondrichthyes fish?

• The internal skeleton is made up of cartilages in Chondrichthyes, whereas it is a bony skeleton in osteichthyes. • Chondrichthyes fish keep their gills open while osteichthyes fish keep those covered by an operculum. • Chondrichthyes fish can move their upper jaw freely from the skull,…

What’s the difference between a Moonfish and a Chondrichthyes?

Chondrichthyes vs osteichthyes, both are 2 classes of fish divided scientifically. The number of fish species that have been discovered so far is approximately 34000 around the world which inhabit either salt or freshwater environments. Generally fishes are cold blooded however Opah which is also called as the kingfish and moonfish is warm blooded.

What are the main characteristics of a chondrichthyan fish?

The main characteristics of chondrichthyans fish include jaws, paired fins, paired nostrils, placoid scales, and two-chambered hearts. The body is covered by tough skin with minute placoid scale and mucous glands. They have jaws and paired appendages.

Which is the largest member of the Chondrichthyes family?

The world`s largest member of Chondrichthyes is the plankton-feeding whale sharks ( Rhincodon typus) which can grow up to 18 meters (60 feet) in length with 21.5 tonnes in weight and live up to 130 years. The main characteristics of chondrichthyans fish include jaws, paired fins, paired nostrils, placoid scales, and two-chambered hearts.
