Question

What are the different types of invertebrates?

Answer 1

Phylum Mollusca

Unlike arthropods these animals don’t have segmented body. Mollusca skin has a mantle which secrets a shell. Their skin is soft and the body is bilaterally symmetrical. Mollusca can be found in fresh water and sea water.

Examples for Mollusca,
– Oyster
– Octopus
Phylum Annelida

Annelida group contains many of the worms around. They have segmented bodies made up of 3 layers, hence they can be known as Triploblastic animals. Triploblasticmeans they have 3 layers of skin as outer skin, middle skin and inner skin.
for example earth worm
sandworm
Phyllum Coelentarata

Coelentarata animals have a radially symmetrical body. They are opened through the mouth to external atmosphere. These are diploblastic animals which means their body is made up of 2 layers called Ectoderm Skin and Endoderm Skin.

for example
jellyfish
coral
Phylum Arthropods

Arthropods are animals who do have a segmented body. They have a bilaterally symmetricalbody with a very strong exoskeleton. Arthropods have the ability of adapting to various environments very quickly.

for example
bug honey bee
