What are the different types of invertebrates Class 6?

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).

How many invertebrate species estimated are there in the oceans?

They form a phylum containing over 10,000 species of animals found exclusively in aquatic (mainly marine) environments. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick.

Where can I find invertebrates?

Invertebrates live on land (terrestrial), in the sea (marine) and in water bodies such as lakes and rivers (freshwater). Some species – such as dragonflies – live both on land and in the water, depending on their life stage.

What percentage of animals are insects?
