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. Animals with backbones include mammals, birds, reptiles, amphibians, and fish. Vertebrates make up just 3 per cent of all known animal species.

How do animals with a backbone differ from each other?
A backbone is what makes vertebrates different from invertebrates. The backbone is an important part of a vertebrate’s endoskeleton. A backbone allows larger and heavier animals to move about. Some vertebrates, such as birds and mammals, are warm-blooded.
What are the animals having backbones?
The 5 groups of vertebrates (animals that have a backbone) are fish, amphibians, reptiles, birds, and mammals.
What characteristics are common among animals with backbones?
This chapter outlines characteristics of animals with backbones. Scientists use the word vertebrate to describe this familiar group of animals that includes man. Vertebrates have certain features in common: (1) a vertebral column made out of bone or cartilage; and (2) a hollow dorsal nervous system.
What animals are without backbones?
Sponges, corals, worms, insects, spiders and crabs are all sub-groups of the invertebrate group – they do not have a backbone. Fish, reptiles, birds, amphibians and mammals are different sub-groups of vertebrates – they all have internal skeletons and backbones.
Is snake a vertebrate or invertebrate?
Snakes belong to the vertebrates, along with all other reptiles and amphibians, mammals, birds, and fish. All these animals have an inner skeleton. Bones give structure and strength to bodies. Muscles are attached to bones, and this enables us to move as our muscles contract.
Which animal is not cold blooded?
When I was a kid, I was taught that the animal kingdom could be divided into two groups. Warm-blooded animals, such as mammals and birds, were able to maintain their body temperature regardless of the surroundings. Cold-blooded animals, such as reptiles, amphibians, insects, arachnids and fish, were not.
What organisms are cold blooded?
All reptiles, including snakes, lizards, turtles, tortoises, alligators, and crocodiles, some insects such as the busy dragonflies and bees, amphibians such as frogs, toads, and salamanders, as well as fish, including sharks, are all cold-blooded animals.
Which is the largest animal without backbone?
COLOSSAL SQUID is the largest invertebrate i.e. animal without backbone.
What makes vertebrates unique?
Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
What makes vertebrates unique from other animals?
Like invertebrates, vertebrates span the ecosystems of all 7 continents. The unique traits of some vertebrates, like mammals, allow them to adapt to the cold by growing thick fur. The quicker motion of vertebrates also helps in cases of migration and running from predators.
Are humans vertebrates?
Vertebrates are members of the subphylum Vertebrata (within the phylum Chordata), specifically, those chordates with backbones or spinal columns. Fish (including lampreys, but traditionally not hagfish, though this is now disputed), amphibians, reptiles, birds, and mammals (including humans) are vertebrates.
What animal has no brain?
There is one organism that has no brain or nervous tissue of any kind: the sponge. Sponges are simple animals, surviving on the sea floor by taking nutrients into their porous bodies.
Which animal has loudest voice?
The loudest animal of all Not only can baleen whales emit calls that travel farther than any other voice in the animal kingdom, these giants of the deep also create the loudest vocalisations of any creature on earth: the call of a blue whale can reach 180 decibels – as loud as a jet plane, a world record.
What animal is only found in Madagascar?
Lemurs. Madagascar is the only place in the world where lemurs are found in the wild; the island’s lack of predators and its isolation from the rest of the world has ensured they thrive.
