hey friend,
Invertebrates are the most abundant organisms on earth. They occupy almost all habitats, they can be found crawling, flying, swimming or floating. Invertebrates are the animals without backbone. These animals do not have internal skeleton made of bone. They play a vital role in the earth's ecosystem. About 99 per cent of the known organisms are invertebrates. Out of the planets estimated 15-30 million species about 90% of the animals are invertebrates. These come in may shapes and sizes and provide services that are vital for our survival. The most common vertebrates include sponges, annelids, echinoderms, molluscs and arthropods. Arthropods includes insects, crustaceans and arachnids.
features or characteristics are:-
1) The main characteristic that separates invertebrates from other organisms is the absence of the spinal column and backbone.
2) They are multicelluar organisms, they completely lack cell walls.
3) They are devoid hard bony endoskeleton. Due to the lack of complex skeletal systems, some invertebrates tend to be slow and small in nature.
4) They do not have lungs for respiration.Respiration is through skin.
5) they are motile..
6) They can not make their own food, are heterotrophs
7) Members of this phylum are commonly known as sponges
8) ater transport or Canal system - Sponges have water transport system. Water enters through minute pores (ostia) in the body wall into a central cavity known as spongocoel. From the spongocoel water goes out through the osculum. This water system aids in food gathering, respiratory exchange and removal of wastes.
9) Examples: Sycon, Euspongia, Spongilla
hope it helps ✌
