Animals, especially those people perceive as cute , have the undisputable ability to make people smile and take out their phones to snap dozens of pictures , potentially spamming their friends’ social media feeds.
While beauty is in the eyes of the beholder, getting close to certain creatures is always a great experience . And they don’t have to be dangerous  such as tigers, lions or even bears. Some fascinating species you have probably never heard of are just about an inch long; others are rarely seen by people.
No matter how hard many people try, most can’t possibly fathom the variety of species that live on Earth .
About 8.7 million is the new, estimated total number of species in the world, according to research . This is the most precise calculation ever offered – with 6.5 million on land and 2.2 million in oceans . The number had been estimated previously at 3 million to 100 million.
New kinds are found every few years in popular places  such as the Highlands of Costa Rica. Imagine if the animal was transparent and you could see the insides of its stomach. Did you think that was possible?
