Porifera: The word Porifera” means organisms with holes”. The canal system helps in circulating water, food, oxygen. They are non-motile with cellular level of organization and mainly marine organisms with hard outer coat called as Skeleton. They are commonly called as Sponges. Ex. Spongilla, Sycon
Annelida: The word Annelida “ means organisms with metameric-segmented”. They are bilaterally symmetrical Triploblastic(three layers of cells) with closed circulatory system, familiar with earth worms. The Coelom is called as true Coelom. Ex. Neris, Earth worm, Leech
Arthropoda: The word Arthropoda “means organisms with jointed legs” They are bilaterally symmetrical Triploblastic(three layers of cells ), familiar with cockroaches. The Coelom is blood filled called as Haemo Coelom. Ex. Prawn, Scorpion, Housefly
Amphibians: These are commonly called as “Amphibians” because they can live on land and in water”. Body is streamlined and a webbed foot/ foot for locomotion. Gills or lungs or skin for respiration, heart is three chambered, cold blooded, skin is lack of scales, plates. They are cold-blooded animals. They lay eggs. Ex. Rana, Hyla

Porifera
The members of this phylum are commonly known as sponges
2. They are generally marine. , and mostly asymmetrical
3. They have cellular level of organisation
4. In this the sponges have water transport or canal system .
5. Water enters through minute pores ( Ostia) in the body wall into a central cavity spongocoel from were it goes out throught the osculum
6. Digestion is interact cellular
7. The body is supported by a skeleton made up of spicules
8. Sexes are not separated .
9. Fertilisation is internall and development is indirect having a larval stage which is morphological lay distinct dp from the adult
ARTHROPODA.
This is the largest phylum of animalia
2. They have organ system level of organisation
3. Bilaterally symmeterricall
4. Triploblastic. , segmented and coelom ate animals
5. The body of the Arthropods is covered by a chitinuous exoskeleton .
6. They have joined appendages
7. Fertisation is. Usually internal
8. They are mostly oviparous
9. Development may be direct or indirect
ANNELIDA
1. They may be aquatic , terrestrial or free living
2. Organ system level of organisation
3 Bilaterally symmetrical
4 Triploblastic , metamerically segmanted and coelom ate animals
5. A closed circulatory system is present
6. Reproduction is sexual
AMPHiBIA.
1. Live in aquatic as well as terrestrial habitats
2. Most of them have two pairs of limbs
3. Body is divisible into head and trunk
4. The amphibian skin is moist without scales.
5. Eyes have eyelids
6. Respiration is by gills, lungs , and through skin
7. The heart is 3 chambered .
8. They r cold blooded animals
9. Sexes are separated
10. Fertilisation is external
11. They are oviparous and development is direct
