what are the 10 phylum of kingdom animalia along with their specific features and examples?
I am giving you features of some phylums.
1. Porifera:
They are mostly marine and non-motile.
They are mostly found attached to rocks.
They show cellular level of organization. Their body is not organized into tissues and organs.
Their bodies are porous. Their body has holes or pores all over, which allows the circulation of water throughout the body and bring in food and oxygen.
2. Platyhelminthes:
They are mostly parasitic (e.g. tapeworm, liver flukes). However, some may be free living (e.g. Planaria).
True body cavity is absent.
They show bilateral symmetry.
They show an organ system level of organization.
In addition to ectoderm and endoderm, a layer of cells called mesoderm is found between these two layers. Therefore, these are triploblastic animals.
3. coelenterates:
They are exclusively marine animals.
Body cavity is present.
They have a tissue level of organization and lack organs and organ systems.
Their body is made up of two layers of cells; the outer layer is called ectoderm and the inner layer is called endoderm.
Most of these animals have radial symmetry.
4. phylum Nematoda:
They are bilaterally symmetrical and triploblastic.
They have a cylindrical body with tapering ends.
They have an organ system level of organization.
They are parasitic animals.
False body cavity or pseudocoelom is present.
5. annelids:
They may be free-living or parasitic.
They are bilaterally symmetrical, and their body is segmented.
They have three germ layers. Thus, they are triploblastic animals.
They possess true organs inside their body structures.
True body cavity or coelom is present (schizocoelom).
6. arthropods:
They show bilateral symmetry.
Triploblastic animals.
Segmented body like those of annelids.
Schizocoelom is present.
7. Chordata:
All members of the phylum chordate possess a notochord. However, some animals such as Balanoglossus, Amphioxus, Herdmania, etc. have a notochord, which is either absent or does not run the entire length of the animal’s body. Therefore, these animals are kept in a separate sub-phylum called Protochordata, and the rest of the chordates are included in the sub-phylum vertebrata. The members of the sub-phylum vertebrata are advanced chordates. They are divided into five classes: Pisces, Amphibian, Reptilia, Aves, and Mammalia.
Animals in Vertebrata are classified into five classes:
8.
Echinodermata are a group of spiny, exclusively marine invertebrates.These animals are radially symmetrical and some of their general characters include,
- Body triploblastic and coelomate
- Possess water vascular system that transports nutrients and oxygen to the different parts of the animal.
- Examples include sea star, sea cucumber, sea urchin etc.
9.
It is the second largest phylum after arthropods. It includes snail, octopus, Pila, mussel, Unio etc.
