THE FIVE VERTEBRATE GROUPS Characteristics of the Five Vertebrate Groups. Fish. The body of the fish is covered in scales and has fins attached to help it move through the water. Fish breathe using gills which take oxygen out of the water.When male and female fish mate, the eggs often meet the sperm in the water.This is called external fertilization. Examples of fish are the herring, which lives in the sea, and the pike which is a freshwater fish.Amphibians. The skin of amphibians is very thin and must always be kept wet because amphibians breathe through their skin.his is called external fertilization.

- This is unique in the vertebrate world, because fish, reptiles, birds, and mammals are all born as small versions of the adult, not a completely different form. This dual life, one aquatic with gills and one terrestrial with lungs, may be representative of the evolution of animals out of water and onto dry land.hen you are a vertebrate, too! Vertebrates make up most of the animals that we are familiar with. Exceptions to this would be things like an insect, an octopus, a lobster or crab, a jellyfish, or a clam. Most everything else is a vertebrate, with a backbone and other bones.

Wildlife Fact Sheets Fish are scaled, cold-blooded vertebrates found in water environments. They fall into three main groups: agnatha or jawless fish, chondrichthyes or cartilaginous fish and osteichthyes or bony fish. Most fish lay eggs, though a few species give birth to live young.

Fish anatomy The skeleton of the fish is either made of cartilage (cartilaginous fishes) or bones (bony fishes). The main features of the fish, the fins, are bony fin rays and, except the caudal fin, have no direct connection with the spine.They are supported only by the muscles. The ribs attach to the spine.he bony fish lineage shows more derived anatomical traits, often with major evolutionary changes from the features of ancient fish. They have a bony skeleton, are generally laterally flattened, have five pairs of gills protected by an operculum, and a mouth at or near the tip of the snout.

- The shape of fishes fins isprobably the most noticedfeature on the fish body. Finsare composed of two groups,unpaired and paired. Theunpaired fins are the dorsal,caudal, and anal; the pairedfins are called pectorals andpelvics, or ventrals.Paired Fins Pectoral fins are present inalmost every fish.They arefound behind the gill cavity, andare prominent. In primitivefishes, the pectoral fins arefound lower on the body, nearerthe ventral side. In somecases, these fins look like anarm-like extension.aired Fins Pectoral fins are present inalmost every fish. They arefound behind the gill cavity, andare prominent.

What Is a Cartilaginous Fish? Characteristics of Cartilaginous Fish: In addition to the difference in their skeletons, cartilaginous fish have gills that open to the ocean through slits, rather than the bony covering that is present in bony fish. Different shark species may have different numbers of gill slits.Cartilaginous fish may also breathe through spiracles, rather than gills.nswer: Cartilaginous fish are fish that have a skeleton made of cartilage, rather than bone. All sharks, skates, and rays (e.g., the southern stingray) are cartilaginous fish. These fish all fall into the group of fish called the elasmobranchs.

- A fish is any member of a paraphyletic group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish, as well as various extinct related groups.ecause the term fish is defined negatively, and excludes the tetrapods (i.e., the amphibians, reptiles, birds and mammals) which descend from within the same ancestry, it is paraphyletic, and is not considered a proper grouping in systematic biology.

Life Science: Session 6 Fish that arose later, including the sharks and the bony fish, have jaws. Jaws represent a much more efficient and effective mode of capturing, feeding on, and swallowing prey. Lungs and limbs: In order for vertebrates to succeed on land, they had to be able to breathe and move around.

Invertebrate vs. Vertebrate Animals can be classified into two main groups: vertebrates and invertebrates. The main difference between vertebrates and invertebrates is that invertebrates, like insects and flatworms, do not have a backbone or a spinal column. Examples of vertebrates include humans, birds, and snakes.ifferences in Physical Characteristics. Vertebrates have a skeletal structure with a spinal column or backbone. Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.

Ray-Finned Fishes, Lobe-Finned Fishes, and Sharks! Ray-Finned Fishes, Lobe-Finned Fishes, and Sharks! 2 Comments. The cartilaginous fishes are a group of about 1,000 species and share many things in common, including the presence of jaws, paired fins, a two-chambered heart, and bodies made of cartilage. By far the largest group of fish are the bony fish. Eight species of bony fish make up a small group called lobe-finned fish, including the lungfish, a fish with the ability to breathe air, that can even drown if it is kept in water too long. Another 27,000 species make up the ray-finned fish. Remember from above that there are a total of slightly less than 58,000 species of all vertebrates. It is clear that bony, ray-finned fish are the most common vertebrates. The lungfish is one of only eight species of lobe-finned bony fish.

Vertebrate Vertebrates include the jawless fish and the jawed vertebrates, which includes the cartilaginous fish (sharks and rays) and the bony fish. A bony fish clade known as the lobe-finned fishes is included with tetrapods, which are further divided into amphibians, reptiles, mammals, and birds.he central nervous system of vertebrates is based on a hollow nerve cord running along the length of the animal. Of particular importance and unique to vertebrates is the presence of neural crest cells.

perch dissection2 The perch is an example of a ray-finned fish. Its fins have spiny rays of cartilage &/or bone to support them. Fins help the perch to move quickly through the water and steer without rolling. The perch also has a streamline body shape that makes it well adapted for movement in the water.

- Characteristics of Vertebrates Vertebrates (subphylum Vertebrata) are chordates with aspinal column. The name vertebrate comes from the indi-vidual bony segments called vertebrae that make up thespine. Vertebrates differ from the tunicates and lancelets intwo important respects: 1. Vertebral column.In vertebrates, the notochord isreplaced during the course of embryonic develop-ment by a bony vertebral column. The column is aseries of bones that encloses and protects the dorsalnerve cord like a sleeve (figure 48.8).haracteristics of Vertebrates Vertebrates (subphylum Vertebrata) are chordates with aspinal column.

Fish - Structure and Function External features. Nostrils. The nostrils of fish do not open into the back of the mouth as do those of mammals, and are not, therefore, for breathing. They lead into organs of smell which are as a rule, very sensitive, so that a fish can detect the presence of food in the water at considerable distances. Eyes.

Fish Anatomy Fish Anatomy. The following illustration of a largemouth bass shows some of the common external features that are used to describe the differences between fish that are described in more detail below. Fish are animals that are cold-blooded, have fins and a backbone. Most fish have scales and breathe with gills.
