Porifera
NO TISSUES OR ORGAN SYSTEMS
1. Contain a few specialized cells
2. Asymmetrical
3. Adults are SEssile
4. Tiny pores all over body (ostia)
-central opening osculum
Cnidaria
1. Soft bodied
2. stinging tentacles
3. radial symmetry
4. Specialized tissues
-2 germ layers
-endo and ecto
Echinodermata
- spiny skeleton
-internal skeleton
-water vascular system
-radial symmetry
-deuterostome
Annelida
1. Body divided into segments that are separated by
septa (internal walls)
2. Setae =>bristles attached to each segment
3. True Coelom (true cavity)
Arthopoda
1.JOINTED APPENDAGES
Greater mobility and locomation
2. Tough exoskeleton => chitin
3. Segmented: 3 head, thorax, abdomen
Platyhelminthes
1.unsegmented
2. Flattened body
3. Acoelomate
-no coelom between tissues
4. Bilateral symmetry
5. Cephalization
6. Tissues
7. Gastrovascular cavity with pharynx
Mollusca
1. soft bodied
2. Internal or External shell
3. Free-swimming larva Trochopore
4. Four parts
-foot, mantle, shell, visceral mass
Chordata
1.notochord
-dorsal, hollow, nerve cord
-post anal tail
-pharyngeal pouches
Nematoda
1.Slender, unsegmented, tapering ends
2. Free living and Parasitic
3. 3 Germ layers
4.Body cavity: pseudocoelom
Thank you ...I hope it's helpful ☺

Animal Kingdom➫ A category of living organisms comprising all animals Compare plant kingdom & mineral kingdom.
➧ Some Phylum in Animal Kingdoms are:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❶❭ Porifera:-━━━━━━━━━━━━━━━☟
❱ Body is cylindrical & asymmetrical.
❱ Canal system is present.
❱ Cellular level of organisation.
❱ It is diploblastic.
❱ They reproduce by budding in Asexual Reproduction.
❱ Special cells are choanocytes.
❱ Skeleton is in the form of spicules.
▶Ex:- Sycon & Sponges
❷❭ Coelenterata:-━━━━━━━━━━━━━━━☟
❱ Body is Radially symmetrical.
❱ Canal system is absent.
❱ Tissue grade level of organisation.
❱ Body wall is diploblastic.
❱ Opening served by mouth & anus.
❱ Special Cell or Cnidoblasts.
❱ It occurs in the form of polyp & Medusa.
❱ It have gastrovascular cavity.
❱ It poses tentacles called Nematoblasts.
▶Ex:- Hydra & Jellyfish
