At 1.4 pounds and 4.9 inches tall, Ducky, a yappy short-coat Chihuahua from Charlton (Massachusetts, USA), holds the Guinness World Record for the world's smallest living dog (by height). Ducky succeeds Danka Kordak of Slovakia, a Chihuahua who measured 5.4 inches tall. The smallest dog ever,according to Guinness, was a dwarf Yorkshire terrier who stood 2.8 inchestall.

2. World's Smallest Snake

(10.1 cm (4-inch) long)

Leptotyphlops carlae is the world's smallest species of snake, with adults averaging just under four inches in length. Found on the Caribbean island of Barbados, the species --which is as thin as a spaghetti noodle and small enough to rest comfortably on a U.S. quarter-- was discovered by Blair Hedges. 

3.World’s Smallest Fish

(7.9 mm (0.3-inch) long)

On January 2006, the world's smallest fish was discovered on theIndonesian island of Sumatra: a member of the carp family of fish, the Paedocypris progenetica. It is the world's smallest vertebrate or backboned animal; only 7.9 mm (0.3 inches) long. 

4.World’s Smallest Horse

(43.18 cm (17-inch) tall)

The little horse was born to Paul and Kay Goessling, who specialize in breeding miniature horses, but even for the breed Thumbelina is particularly small: she is thought to be a dwarf-version of the breed. At just 60 lb and 17-inch tall, the five-year-old Thumbelina is the world’s smallest horse. 

5.World’s Smallest Cat

(15.5 cm (6.1-inch) high and 49 cm (19.2-inch) long)

Meet Mr. Peebles. He lives in central Illinois, is two years old, weighs about three pounds and is the world's smallest cat! The cat's small stature was verified by the Guinness Book of World Records on 2004. 

6.World's Smallest Hamster

(2.5 cm (0.9-inch) tall)

Only slightly bigger than a 50p piece, PeeWee is the smallest hamster in the world. Weighing less than an ounce, the golden hamster stopped growing when he was three weeks old - his five brothers and sisters went on tomeasure between 4in and 5in. 

7.World's Smallest Chameleon

(1.2 cm (0.5-inch) long)

The Brookesia Minima is the world's smallest species of chameleon. This one is just half an inch. Found on the rainforest floor of Nosy Be Island off the north-west coast of Madagascar, females tend to be larger than males. 

8.World's Smallest Lizard

(16 mm (0.6-inch) long)

So small it can curl up on a dime or stretch out on a quarter, a typical adult of the species, whose scientific name is Sphaerodactylus ariasae is only about 16 millimeters long, or about three quarters of an inch, from the tip of the snout to the base of the tail. It shares the title of "smallest" with another lizard species named Sphaerodactylus parthenopion, discovered in 1965 in the British Virgin Islands. 

9.World’s Smallest Cattle

(81 cm (31-inch) height)

The world’s smallest cattle is a rare breed of an Indian zebu called theVechur cow. The average height of this breed of cattle is 31 to 35 inches (81 to 91 cm). The photo above shows a 16 year old Vechur cattle as compared to a 6 year old HF cross-breed cow. 

10.World's Smallest Seahorse: 16 mm (0.6-inch) long

The creature, known as Hippocampus denise, is typically just 16 millimetres long - smaller than most fingernails. Some were found to be just 13 mm long. H. denise lives in the tropical waters of the western Pacific Ocean, between 13 and 90 metres beneath the surface.

Pit Viper

• There is a group of snakes that are known as Pit Vipers.
•  Not only are these snakes venomous they also have a very 'cool' heat sensing system. 
• This helps these snakes to find prey in the dark, which is when most snakes like to hunt. The ‘pit’ is a special organ in between the eyes and the nostrils. 

• The pit senses body heat from animals and gives the snake a ‘picture’ of that animal. 
• The snake can then attack it. Some pit vipers will bite and poison the prey and then release it.
•  It will follow the dying animal, using its heat sensors, until it stops and the snake can swallow it.
•  Most pit vipers hunt at night when the air is cooler and the heat from rodents and other prey is most obvious to them. 
• The ‘heat picture’ from larger animals will tell the snake that a quick escape is a good idea.
• All rattlesnakes are Pit Vipers.  Water Moccasins, Horned Desert Viper, Lance-head, Eyelash Viper, the Copperhead, and some Tree Boas are a few other examples of pit vipers.

Emerald Tree Boa.

The Emerald tree boa looks similar to the Green tree python . They have an irregular zigzag stripe along their back and they reach lengths between 1.5 and 2 m (5 - 5.5 ft).They spend their days coiled over branches with their head resting in the middle of the coils and they hunt at night. They live in the typical rain forest and wetlands.

These non-venomous snakes kill their prey by constriction, holding them with their mandibles and wrapping their body around these, immobilizing them and squeezing them until they die from asphyxiation. The Emerald Tree Boa has mostly arboreal habits, and rarely comes down to the ground level. They move very fast through the foliage and tree tops. When resting, they cling firmly to a branch with its tail and wrap the rest of the body.

This species is not globally threatened, according to the International Union for Conservation of Nature. Is included in Appendix II of CITES. Habitat destruction is the main threat to be taken into account for their future survival.
