| DESCRIPTION | LIVING BEING | EXPLANATION |
| Bird with the largest wing span | Albatross | The Wandering Albatross of the southern oceans has the largest wingspan for any bird. The largest recorded wing span is about 12 ft for a very old male albatross. |
| Heaviest snake | Anaconda | Found mainly in tropical jungles of South America, the heaviest anaconda measured so far was nearly 500 lb. |
| Fastest growing plant | Bamboo | Some species of bamboo grow upto 3 ft per day and can reach heights of upto 120 ft. Among the trees, the fastest growing one is Eucalyptus Salinga. Botanically, bamboo is treated a grass and not a tree. |
| Fastest land animal | Cheetah | No one can beat a cheetah over short distances (600 yds or so). They have been found to touch speeds of over 65 mph over plain ground. But over sustained distances, the Pronghorn Antelope is the fastest. |
| Fastest fish | Cosmopolitan Sailfish | |
| Heaviest dog (breed) | English Mastiff or St. Bernard | Both English Mastiff and St Bernard are considered to be among the heaviest dogs in the world. Males from both the breeds have been regularly weighed in at 170-200 lb. |
| Longest bone in the human body | Femur | The adult human body has a total of 206 bones. The longest and strongest one is the thigh bone also called the femur. It may be about 28% of a person's stature. Often people think the back bone is the longest. In fact it is not a single bone but a collection of many smaller bones (vertebrae). |
| Largest muscle in the human body | Gluteus Maximus | Gluteus Maximus is better known as the buttock muscle which extends the thigh. Sometimes in pregnant women the womb can increase in weight to nearly 2 lb. This is larger than the buttock muscles of most bodybuilders. But then this is not permanent and hence not considered the largest muscle. |
| Largest predatory fish | Great White Shark | |
| Fastest marine animal | Killer Whale | Killer whales (orcinus orca) have been found to be the fastest marine animals. Dall's porpoise may also match the killer whale in speed for short bursts. |
| Heaviest internal organ in the human body | Liver | The liver is the organ that secretes bile and purifies the blood. |
| Longest cells in the human body | Nerve Cells (Neurons) | Some of the motor neurons may be as long as 4.25 ft. There might be nerve cells that are as long as the human body itself. Nerve cells are used for carrying information from one part to another via electrical impulses at speeds over 200 mph. |
| Most common blood group in humans | O | Nearly half the world's population has blood Group O. |
| Largest bird | Ostrich | A male ostrich may be as tall as 9 ft and weigh as much as 345 lbs.Ostriches also hold the record for highest speed on land for a bird. |
| Largest carnivore on land | Polar Bear | |
| Smallest bone in the human body | Stirrup | Stirrup is one of the three auditory bones in the human ear. It is also called the stapes. It measures 2.6 to 3.4 millimetres and weighs 2 to 4grams. |
| Most common non-contagious disease | Tooth decay | Nearly everyone suffers from some sort of tooth problem at least once in his/her lifetime. |
