Answer 1

Attributes of Animalia Kingdom Classification

The animalia kingdom consists of various multicellular eukaryotic animals. It is one of the kingdoms among the five kingdom scheme of classification (by Whittaker).

Answer 2

Answer :

Kingdom animalia includes the organisms that are multicellular and heterotophic. The sub-parts of kingdom Animalia are :-

• Vertebrates
• Invertebrates

Explanation :

Vertebrates

• They have internal skeleton
• Backbone is present
• Heart is on the ventral side of the body
• Nerve cord is hollow which is present on the dorsal side of the body.
• Vertebrates have two pairs of limbs.

The vertebrates are divided into :-

• Class Pisces
• Class amphibia
• Class reptilia
• Class aves
• Class mammalia

Class Pisces :

• They have streamlined body, their body is narrow at the font and rear ends.
• Fishes are cold-blooded animals. their body is smooth and shiny and covered with scales for protection.
• Their leaves are modified into fins for swimming and they have a special breathing organ called gills.
• Their heart is two chambered.

Class Amphibia :

• Amphibians are cold-blooded animals.
• They have a thin moist skin which may be smooth or rough and they have two pairs of limbs.
• They breathe with lungs on land and through their moist skin in water.
• Their heart is two chambered.

Class reptilia :

• Reptiles are cold-blooded animals.
• They have dry skin covered with scales.
• They breathe through lungs.
• most of them have three-chambered heart ( except crocodile )

Class Aves :

• They are warm blooded animals.
• They have streamlined body.
• They are the only animals whose body is covered with feathers and they breathe through lungs.
• They have a four-chambered heart.

Classs Mammalia :

• Mammals are warm-blooded animals and they have hair on their body.
• They breathe through lungs.
• They have four-chambered heart.

Invertebrates

• They have no internal skeleton
• Backbone is absent.
• Heart is on the dorsal side of the body
• Nerve cord is solid which is present on the ventral side of the body.
• Vertebrates have three or more pairs of limbs.

The invertebrates are divided into :-

• Porifera
• Cnidaria
• Platyhelminthes
• Nematoda
• Arthropoda
• Mollusca
• Annelida
• Echinodermata

Porifera :

• These animals have a large number of openings on their body.
• There is a large pore at the top from where the water passes out.
• They don't move from one place to another.

Cnidaria :

• Cnidaria have a radially symmetrical body.
• The body is hollow, tube-like and has one opening called the mouth.
• They are found in aquatic, mostly marine habitat.

Platyhelminthes :

• Earthworm are the most simplest worms or animals without legs.
• They have bilaterally symmetrical body.
• They have only one opening.

Nematoda :

• They have cylindrical, narrow, unsegmented surface.
• They have bilaterally symmetrical body.

Annelida :

• They are generally found on moist soil and pond water.
• They have soft, cylindrical and bilaterally symmetrical body.
• They have a special organ "nephridia"

Arthropoda :

• They are mostly found in air, on land and ponds.
• The body is segmented and divided into three regions, head, thorax and abdomen.
• All arthropods have paired appendages with many joints.

Mollusca :

• Mollusca have soft unsegmented body with outer hard shell.
• Some molluscs have a single shell.
• Some molluscs such as octopus, squids and cuttlefish have a cell inside their body and four a pair of arms.

Echinodermata :

• They have an unsegmented body.
• They have a mouth on the lower side.
• They move with the help of tube like feet. each foot has na cause at the end that are used to capture and hold the prey.
