What are the 5 classes of invertebrates?

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 5 main groups of invertebrates?

Familiar examples of invertebrates include arthropods (insects, arachnids, crustaceans, and myriapods), mollusks (chitons, snail, bivalves, squids, and octopuses), annelid (earthworms and leeches), and cnidarians (hydras, jellyfishes, sea anemones, and corals).

What are the main groups of invertebrates?

3 Familiar Groups of Invertebrates

There are three main groups that may be very familiar to you: insects, arachnids and crustaceans.

What are the 5 class of animals?

The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds.

How many different types of invertebrates are there?

So far, 1.25 million species have been described, most of which are insects, and there are millions more to be discovered. The total number of invertebrate species could be 5, 10, or even 30 million, com- pared to just 60,000 vertebrates. One reason for the success of invertebrates is how quickly they reproduce.

How do we classify invertebrates?

Invertebrates as a group do not have a specific classification. Since vertebrates are classified by the chordate subphylum vertebrata, invertebrates are any other animal that is classified outside of that class.

What are the nine classes of invertebrates?

Nine phyla represent the list of invertebrates: Porifera, Cnidaria, Platyhelminthes, Nematoda, Rotifera, Mollusca, Annelida, Arthropoda, & Echinodermata.

What are the 6 phyla of invertebrates?

What are the subgroups of invertebrates?

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.

What are the 4 classes 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 are the 5 main groups of the animal kingdom?

Let's take a tour of the five main vertebrate groups alive today: the fishes, amphibians, reptiles, birds, and mammals.

What are vertebrates and invertebrates animals?

Animals can be classified as either vertebrates or invertebrates. Vertebrates are animals that have a backbone inside their body. ... Invertebrates don't have a backbone. They either have a soft body, like worms and jellyfish, or a hard outer casing covering their body, like spiders and crabs.

How many animal phyla are invertebrates?

There are over 30 phyla dedicated to invertebrates. Major invertebrate phyla that you should know include porifera, cnidaria, platyhelminthes, nematoda, mollusca, annelida, arthropoda, and echinodermata.

What are invertebrates examples?

More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid.

What is an invertebrate ks1?

Invertebrates are animals that don't have a backbone. Some have soft bodies, like worms, slugs and jellyfish. Other invertebrates, like insects, spiders and crustaceans, have a hard outer casing called an exoskeleton. This protects their body a bit like a suit of armour.
