Classification of animals vertebrates and invertebrates
What are the classification of vertebrates and invertebrates?
Animals can be classified into 2 main groups: vertebrates and invertebrates. Invertebrates are animals without a backbone. Vertebrates have an internal skeleton (endoskeleton) made of bones. Most but not all invertebrates have a hard outer casing called an exoskeleton.
What are the classification of invertebrate animals?
The Invertebrates unit explores six groups of invertebrates— poriferans (sponges), cnidarians (such as sea jellies and corals), echinoderms (such as sea urchins and sea stars), mollusks (such as octopuses, snails, and clams), annelids (worms), and arthropods (such as insects, spiders, and lobsters).
What are the 7 classifications of invertebrates?
The most familiar invertebrates include the Protozoa, Porifera, Coelenterata, Platyhelminthes, Nematoda, Annelida, Echinodermata, Mollusca and Arthropoda.
What are the 5 main classifications of vertebrates?
The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds.

What are the 4 major characteristics of vertebrates?
Key Points. As chordates, vertebrates have the same common features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
What are the characteristics of vertebrates and invertebrates?
Invertebrates – animals without a backbone. Vertebrates – animals with a backbone. The animals have been divided into two groups based on the presence or absence of a backbone. The backbone is the observable feature that defines whether the animal is a vertebrate or an invertebrate.

How many types of invertebrates are there?
Types of Invertebrates
Eighty-five percent of invertebrates – some 923,000 species – are arthropods. Mollusks have approximately 100,000 distinct species. Some of the most common types of invertebrates are: protozoans – single-celled organisms such as amoebas and paramecia.
What are the 9 major Phylums of invertebrates?
Major invertebrate phyla that you should know include porifera, cnidaria, platyhelminthes, nematoda, mollusca, annelida, arthropoda, and echinodermata.
What is the classification of arthropods?
The phylum Arthropoda is commonly divided into four subphyla of extant forms: Chelicerata (arachnids), Crustacea (crustaceans), Hexapoda (insects and springtails), and Myriapoda (millipedes and centipedes).

What is the main difference between vertebrates and invertebrates?
Vertebrates are more complex organisms when compared to invertebrates. The primary difference between the two is that vertebrates possess a backbone and an internal skeleton.

- Phylum Mollusca.
- Phylum Annelida.
- Phylum Arthropods.
- Phylum Coelenterata.
What is the example of invertebrates?
An invertebrate is an animal without a backbone. In fact, invertebrates don’t have any any bones at all! Invertebrates that you may be familiar with include spiders, worms, snails, lobsters, crabs and insects like butterflies. However, humans and other animals with backbones are vertebrates.

What are the characteristics of vertebrates and invertebrates?
Invertebrates – animals without a backbone. Vertebrates – animals with a backbone. The animals have been divided into two groups based on the presence or absence of a backbone. The backbone is the observable feature that defines whether the animal is a vertebrate or an invertebrate.
Is snake a vertebrate?
Snakes belong to the vertebrates, along with all other reptiles and amphibians, mammals, birds, and fish. All these animals have an inner skeleton.
Which is the largest group of invertebrates?
Answer and Explanation: The largest group of invertebrates is the Arthropoda.
What is the main characteristic of vertebrate animals?
backbone
The main distinguishing feature of vertebrates is their vertebral column, or backbone (see Figure below). The backbone runs from the head to the tail along the dorsal (top) side of the body. The vertebral column is the core of the endoskeleton. It allows a vertebrate to hold its shape.
