Animals are mainly categorized into two :

(1)Vertebrates: Animals with backbone
(2)Invertebrates:Animals with no backbone (bacteria etc.)

abstract class Animal {
	
	abstract void feed();
	
	abstract void respire();
	
	abstract void reproduce();
	
}

abstract class Invertebrates extends Animal {}


abstract class Vertebrates extends Animal {
	abstract void move();
}


abstract class Mammals extends Vertebrates {}


abstract class Birds extends Vertebrates {}
	

abstract class Fish extends Vertebrates {}


abstract class Reptiles extends Vertebrates {}

The Animal Family can be broadly classified as below sub categories:
> Bird Family
> Mammal Family
> Insect Family
> Fish Family

Animals can be also classified based on many of their characteristics, such as:
> Carnivores vs Herbivores
> Scavengers
> Land vs. Water Animals
> Noctural or Night Animals
> Cold Blooded vs Warm Blooded Animals
> Vertebrates vs. Invertebrates
> Fly / Swim / Run
> Number Of Legs

class Animal {
   String Name ;
   List <Characteristic> Characteristics ;
   .....
};

class Characteristic {
   String Name;
   ...
};

class Carnivores : public Characteristic {
  bool isCarnivores ();
  ...
};

class Legs : public Characteristic {
  int NumberOfLegs ();
  ...
};

class animal  //base of all
{
var parents[],childrens[],species,behaviors[]; //behaviours may contain it is carnivorous or hervivorous , color etc .
animal(){
}
~animal()
{
}
}

For me makes sense to reuse all the effort made in taxonomy, I would create:

module Biology
      module Kingdom
        module Animalia
        .... all other kingdoms
      module Phylum
        module Chordata
        .... all other phylums
      module SubPhylum
        ...
      module SuperClass
        ...
      module Class
        module Mamalia
        .... all other classes
      module Order
        module Carnivora
        .... all other orders
      module Family
        module Felidae
        .... all other families
      module Genus
        module Panthera
        .... all other Genus
      module Species
        module Tiger
        .... would include Panthera, Felidae, Carnivora, Mamalia, Chordata and Animalia.

To ease the process of writing all this code I would try to fetch data from an API or maybe scrapping Wikipedia.
