It includes identifying and classifying animals based on different norms and guidelines. The different characteristics based on which animals are classified encompass various different aspects like, cells, tissues and body structure. This classification of the animal kingdom is also most commonly known as animal taxonomy.



5 : Zoological Museums
One of the world’s largest zoological museums is at Cambridge University in England. The zoological museum at Cambridge prides itself in having the largest collection of zoological species. The major attraction here is the Finback whale skeleton which is over 70 ft long. It is the largest species in an exhibition in the entire world, it’s dismantling alone can take up to 5 weeks.

Aristotle is popularly known as ‘The father of Zoology’. His greatest contribution is generally considered as the development of the theory of the genome codes. His practice of keeping methodical observations and keeping journals of every observation about animals and the wildlife paved the way for many great workers in the future and made other discoveries much easier.



9 : Beginning of Zoology
According to some historians, Conrad Gesner, around the 1500’s wrote the Historiae Animalium which is considered the beginning of the zoology as we know it today.

The various kinds of sharks which can be seen in the world are: Angel shark, Basking shark, Black tip shark, Blue shark, Bull shark, Cookie-cutter shark, Great white shark, Hammer-head shark, Mako shark, Nurse Shark, Port Jackson shark, Sand tiger shark, Spiny dog fish shark, Whale shark, Tiger shark, Thresher shark, White tip reef shark, Wobbegong shark and Zebra shark.



3 : Life since the Devonian Age
For over 430 million years, sharks have been frightfully living on our seas. These beasts have survived around five planet extinctions which have even killed dinosaurs. So, the appearance of sharks dates back since the period of Devonian age.



4 : Razor-sharp teeth
One of sharks pristine features is its teeth which can even devour the hardest of boat hulls in seconds. Sharks used to shed their teeth frequently and these teeth which end up on the ocean floor, gets covered with sand and soon soaks up certain sediments like calcite and silicon oxide which turns their colour into brown.

10 interesting facts about Alligators

The Reptilian Ménage
One of the prime most things that make everyone ambivalent regarding alligators is that they would fallaciously come to a conclusion that both crocodiles and alligators are the same, but they are certainly not. Both the species belong to the same reptilian family of the same order but differ in their nature and external appearances.



2 : Species
Alligators are mainly classified into two different species namely the American alligator (which is quite the more sublime of the two) and the other one being the Chinese alligator. American alligators are mostly found in Florida along the south-eastern part of America whereas Chinese alligators are found along the Yangtze River but these are a much endangered species and are found quite only a few in numbers.



3 :Food preferences
Unlike crocodiles, alligators are not strict carnivores. They also consume fruits and can even act upon as the potential seed dispersers which help to maintain the flow of the ecosystem, which is not seen much in the case of other reptiles.



4 :Habitat
Alligators often stay in groups which are collectively referred as 'Congregations'. Like crocodiles, alligators are slow in movement in the land while they are far more aggressive when hunting underwater with speeds up to 20 mph. These creatures used to live in freshwater environments along the marshlands and wetlands.



5 :Physical nature
In comparison with crocodiles, alligators are far less aggressive and have a much darker external appearance. They have shorter, wider heads to hunt down preys easily. Their skin is robust and is strong enough to tackle attacks from its enemies. An average adult alligator can weigh up to 360kgs and grows up to 4 meters in length.



6 :Pioneers of hunting
Alligators are pioneers of hunting as they used to purposely gather sticks above their snouts so that they can invite birds and other miniature creatures within striking distance. This innovative approach towards hunting is seldom found in other reptiles other than alligators.



7 :Exemplary climbers
While approaching an alligator, it is a necessity to keep your distance away from them as they can easily climb walls and trees when provided the required inclination needed for the jump. This helps them to hunt down prey from distances as well.



8 :Reproduction
Alligators usually attain maturity when they grow up to lengths of 1.8 meters. These reptiles used to mate during late spring and while doing so, these animals used to produce an infrasound and form a group courtship which zoologists referred as 'alligator dances'.



9 :The second aorta
The second aorta is a special kind of blood vessel found in alligators which help them to rapidly break down food in their tiny stomachs. Juveniles can intake food up to 23% of their total body weight as this vessel helps it to produce strong stomach acids to digest faster.
