TYPES OF ANIMALS

  Vertebrates

Although not the most numerous group of animals in either number of individuals or in number of taxa, the vertebrates are an endlessly fascinating group of animals. Vertebrates are interesting partly because we are intimately familiar with them, but also because we ARE them. Our species, Homo sapiens, is included within the Vertebrata.     
                                                             

Invertebrates

ANIMALS WITHOUT BACKBONE

Of the million or more animal species in the world, more than 98% are invertebrates. Invertebrates don't have an internal skeleton made of bone. Many invertebrates have a fluid-filled, hydrostatic skeleton, like the jelly fish or worm. Others have a hard outer shell, like insects and crustaceans. There are many types of invertebrates. The most common invertebrates include the protozoa, annelids, echinoderms, mollusks and arthropods. Arthropods include insects, crustaceans and arachnids.

 cannibal

A cannibal is an animal that feeds on others of its own species. This is not an animal unnatural characteristics: around 140 different species show cannibalistic

tendencies under various conditions. Cannibalism is most common among lower vertebrates and invertebrates often due to a predatory animal mistaking one of its own kind for prey.

But it also occurs among birds and mammals, especially when food is scarce.

Carnivores

A carnivores means 'meat eater' animal


CARNIVORES is an animal with a diet consisting mainly of meat, whether it comes from animals living or dead (scavenging). Some animals are

considered carnivores even if their diets contain very little meat but involve preying on other animals Animals that subsist on a diet consisting only of meat are referred to as

obligate carnivores. Plants that capture and digest insects are called carnivorous plants. Similarly fungi that capture microscopic animals are often called carnivorous fungi.

Herbivores

THOSE ANIMALS WHO EATS HERBS,PLANTS. BASICALLY VEGETARIANS .

A herbivore is any organism that normally consumes only autotrophs such as plants, algae and photosynthesizing bacteria.

Omnivores

Omnivores are the animals who eat and digest both animals and plants. They are primary and high level consumers. Humans are omnivorous as they take vegetables and

meat. It include fish, humans, domestic dog, pig, bear, rodents, Opossums, Raccoons, Foxes, Rails, Rhea, Most gulls, Chickens, Crows, Domestic pigeons

Detritivores

An organism that feeds on and breaks down dead plant or animal matter, returning essential nutrients to the ecosystem. Detritivores include microorganisms such as bacteria and protists as well as larger organisms such as fungi, insects, worms, and isopod crustaceans. In a food chain, detritivores are primary consumers.

Scavengers

The word scavenger, in zoology, refers to animals that consume already dead organic life-forms. Scavengers are useful to the ecosystem by feeding on and therefore

breaking down dead animal and plant remains. The remains that are left behind by the scavengers are then used even further by decomposers. Well known scavengers include

vultures, burying beetles, blowflies, and raccoons. Many large carnivores that hunt regularly--such as hyenas and lions--will scavenge if given the chance.
