What are the 9 types of invertebrates?

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

Are invertebrates a class?

Invertebrates or Insects

They are the largest Class of organisms and account for over 75% of all animal species.

What are the 6 groups 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 9 major phyla?

There are 36 recognized animal phyla, of which but nine (Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata) contain the vast majority of described, extant species.

What are the 3 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 main groups of vertebrates?

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

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 10 invertebrate animals?

Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid.

Do all insects have 6 legs?

Insects have only six legs. Spiders, scorpions, mites, ticks, whip scorpions, and pseudoscorpions are all arachnids that can be found in Everglades National Park. Unlike insects, arachnids have eight legs and no antennae, and their body is divided into two main segments: a cephalothorax and abdomen.

What are the 5 phyla of 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.

How many main groups of vertebrates are there?

In order to study them further, vertebrates can be further classified into 5 major groups – Mammals, Reptiles, Fish, Amphibians, and Birds.
