Vertebrates /ˈvɜːrtᵻbrᵻts/ comprise all species of animals within the subphylum Vertebrata /-ɑː/ (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described. Vertebrates include the jawless fish and the jawed vertebrates, which include 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. Extant vertebrates range in size from the frog species Paedophryne amauensis, at as little as 7.7 mm (0.30 in), to the blue whale, at up to 33 m (108 ft). Vertebrates make up about 4% of all described animal species; the rest are invertebrates, which lack vertebral columns.
The vertebrates traditionally include the hagfish, which do not have proper vertebrae, though their closest living relatives, the lampreys, do. Hagfish 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. Others consider them a sister group of vertebrates in the common taxon of craniata.
Today we’re going to look at vertebrate animals. As you know, we can classify animals in various ways, depending on the characteristics we look at. Today, we’re going to some animals by the internal structure of their bodies. According to this feature, we can classify them into... Vertebrate Animals, which have an internal skeleton, that means bones.... And Invertebrate Animals... like this worm, which has no backbone... in fact, no bones at all. All vertebrate animals have an internal skeleton made up of... bones. Bones are very strong, and give bodies their shape, they hold it up, nice and straight. The spine – the backbone – is made of a series of articulated pieces of bone, called the vertebrae, which allow the body to move in a certain way, and flexible. Vertebrate animals’ bodies...
Fishes, lions, monkeys and humans! What's that one common thing about them? Well, they all have a backbone! And that's why they are called Vertebrates. Tune into this video as Dr. Binocs takes you through the world of Vertebrates, which is an important part of the Animal kingdom. The detail video break up is given below. 00:52 – What are Vertebrates? 01:02 – Group of Vertebrates 01:16 – Amphibians 01:40 – Reptiles 02:05 – Birds 02:28 – Mammals Voice Over Artist - Joseph D'Souza, Sreejoni Nag Script Writer & Director - Sreejoni Nag Visual Artist - Aashka Shah Illustrators - Aashka Shah and Kushal Bhujbal Animators - Digambar Bhadre and Aashka Shah VFX Artist - Kushal Bhujbal Background Score - Jay Rajesh Arya Sound Engineer - Mayur Bakshi Creative Head - Sreejoni Nag Producer: Rajjat A...
Animals are classified into different groups based on their characteristics. Invertebrates are animals that do not have a spine, or backbone. Vertebrates are animals that do! Vertebrates are further classified into fish, amphibians, reptiles, birds, and mammals. Come and learn what makes animals a part of these groups in this fun, kid-friendly video!

Join Mr. DeMaio in this fun science lesson for children on vertebrates and invertebrates. You will meet two of Mr. DeMaio's friends, a strange iguana and a familiar crab, as you discover cool facts and information about these two animal groups. Made Using: Yakit! Kids
This video is about vertebrates. It is extremely informative and easy for students to understand.
Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as chordata. And the next time someone asks you who you are, you can give them the facts: you're a mammalian amniotic tetrapodal sarcopterygian osteichthyen gnathostomal vertebrate cranial chordate.
