Osteichthyes The vertebrates include various animal groups such as fish, amphibians, reptiles, birds, and mammals. A fish pertains to any gill-bearing animals lacking limbs with digits. Osteichthyes (bony fish) is one of the taxonomic superclasses of fish. The others are chondrichthyes (cartilaginous fish) and Agnatha (jawless fish). Osteichthyes includes the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii).

- Classes Found In The Phylum- Chordata. All chordates have a number of structures in common: A notochord (noto = the back; chord = string) is present in all embryos, and may be present or absent/reduced in adults. This is the structure for which the phylum was named. The notochord is a rod-like structure that forms the supporting axis. of the embryo and gives birth to the vertebral column in vertebrates. Chordates are sometimes referred to as “vertebrates” because most possess a backbone with vertebrae.

Vertebral column It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord. There about 50,000 species of animals that have a vertebral column. The human vertebral column is one of the most-studied examples.

Whales and other cetaceans are also tetrapods because they are mammals have two front limbs and the two hind limbs are vestiges.

Classification of Animals Animals that lack the backbone are called invertebrates. About 97% of the animal kingdom is made up of the invertebrates. These animals are found in lands, ponds, oceans and other water bodies. They are six groups of invertebrates. They are annelids, mollusks, arthropods, arachnids, echinoderms and protozoa.

- THE NOTOCHORD. Before there vertebrae, there was a notochord. Notochords evolved in invertebrates known as chordates and there are a few living examples of primitive chordates, such as lancets and tunicates. The most primitive fish today, the jawless fish, do not have full-fledged vertebrae, and still depend on the notochord as their primary axial support. Even once vertebrates began to develop vertebrae, these structures arose in pieces around a notochord which still ran uninterrupted from head to tail.

- Hagfish are considered members of the subphylum Vertebrata, because they secondarily lost vertebrae; before this event was inferred from molecular and developmental data, the group Craniata was created by Linnaeus (and is still sometimes used as a strictly morphological descriptor) to reference hagfish plus vertebrates.he Agnatha are ectothermic or cold blooded, with a cartilaginous skeleton, and the heart contains 2 chambers.

Invertebrate Invertebrate is a kind of animal that does not have a spinal column or backbone. It is the opposite of vertebrate, that means if an animal is not a vertebrate (fish, reptile, amphibian, bird, or mammal), it is an invertebrate. The main phyla (groups) of invertebrate animals are: Annelida: segmented worms.

- (Answer #1). One of the most basic ways of categorizing animals is to break them down into animals with backbones and animals that do not have backbones. The animals that have backbones are called vertebrates. This word comes from the word that we use for the bones that make up the backbone.Those bones are called vertebrae so the animals are vertebrates. The animals that do not have backbones are called invertebrates.Some examples of vertebrates include human beings, cats, dogs, fish, elephants, and chickens. Some examples of invertebrates include spiders, worms, and flies. krishna-agrawala | College Teacher | (Level 3) Valedictorian.

- No, a narwhal isn't an invertebrate. Instead, it has a backbone. It belongs to the Chordate phylum, which has mostly vertebrate members. It also belongs to the class of Mammals, which all have backbones.cientists to this day do not have much information at all about the narwhal. Answer #3 They are the unicorns of the ocean! I think you mean 'narwhal' well basically a narwhal is just a type of whale that has a horn.

The Animal Kingdom Most vertebrates have a spinal column made of bones called vertebrae. But some, such as the shark, do not have a bony spinal column. Sharks have vertebrae made of cartilage. All vertebrates are bilaterally symmetrical-that is, the left and right sides of the body are alike.

What are animals with spines called? Any of a large group of chordates of the subphylum Vertebrata (or Craniata), characterized by having a backbone. Vertebrates are bilaterally symmetrical and have an internal skeleton of bone or cartilage, a nervous system divided into brain and spinal cord, and not more than two pairs of limbs.

- 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.agfish do, however, possess a cranium. For this reason, the vertebrate subphylum is sometimes referred to as  Craniata  when discussing morphology. Molecular analysis since 1992 has suggested that the hagfish are most closely related to lampreys, and so also are vertebrates in a monophyletic sense.

Vertebral column Vertebral column of a goat. The vertebral column, also known as the backbone or spine, is a bony skeletal structure found in vertebrates. It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord.There about 50,000 species of animals that have a vertebral column.ertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.

Or just try one of these? Animals that have a backbone are called vertebrates. The backbone is is a column of bones that supports the body, and also protects the spinal cord. The back is made up of many separate bones, called vertebrae. The backbone is part of a vertebrate’s supportive internal skeleton. Most vertebrates have two pairs of limbs. In fish these take the form of fins, but in other vertebrates they are legs, arms, flippers, or wings. Some vertebrates, such as snakes, have no external limbs. Animals with backbones include mammals, birds, reptiles, amphibians, and fish. Vertebrates make up just 3 per cent of all known animal species.

- The original scheme groups hagfish and lampreys together as cyclostomes (or historically, Agnatha), as the oldest surviving class of vertebrates alongside gnathostomes (the now-ubiquitous jawed vertebrates).hey are the only known living animals that have a skull but no vertebral column. Along with lampreys, hagfish are jawless; they are the sister group to vertebrates, and living hagfish remain similar to hagfish from around 300 million years ago. The classification of hagfish has been controversial.
