Hi guys, I'm Hà Serious
Animals take many shapes and forms and come in a great diversity of sizes, from microscopic to the 30 m long blue whale!
Whether you measure in terms of weight, height or length, there is no denying some animals are huge in comparison to others in their class.
The following will be the top 10 largest animals, this list includes the largest species compared to other species,
for example, rhinos and hippos are all very large but will not be on this list but only The elephant is chosen.
10.Goliath Beetles
Hiding in the undergrowth of African tropical forests, Goliath Beetles take the top spot as the heaviest insect in the world!
They weigh up to 3.5 ounces (100 g), grow to a length of 4.5 inches (11.5 cm) and are brown/black/white in colour.
Goliath beetles are also known as the largest beetles on the planet because of their strength: they can lift a load that is 850 times heavier than their own weight.
Goliath beetles eat different types of plant material, fruit, dung and remaining of dead animals.
Goliath beetle are important part of the food chain in ecosystem because they eliminate decaying matter of plant and animal origin.
9.Chinese Giant Salamander
The Chinese Giant Salamander is the largest living amphibian, weighing around 66 lb (30 kg) though they can reach 132 lbs (60 kg), and growing to a length of 6 ft (1.8 m) long.
Having changed little from their ancestors, they are known as living fossils, but despite their fascinating nature, they are endangered and rare in the wild.
They have very poor eyesight, to detect their prey they sense the vibrations in the water. They spend their entire lives under water, but don’t have gills.
They absorb oxygen through their skin. At breeding time, the females lay between 400-500 eggs which the males look after until they hatch.
8.Ostrich
The Ostrich is the largest living bird, with a height of 9 ft (2.7 m) and weight of 344 lbs (156 kg), and at 1.9 in (5 cm) in size, their eyes are the largest of all birds.
They don’t have teeth and can survive without water for days as they can make their own water internally and extract the rest from the vegetation they eat!
When threatened ostriches run although their powerful, long legs can be formidable weapons, capable of killing a human or a potential predator like a lion with a forward kick.
Ostriches are the fast runners of any birds or other two-legged animal and can sprint at over 70 km/hr, covering up to 5m in a single stride.
Saltwater Crocodile
The largest living reptile is the Saltwater Crocodile, growing to an average length of 17 ft (5.2 m), although they can reach 21 ft (6.3m) in length and weigh up to over 2205 lb (1000 kg).
They are distributed widely in brackish and salt waters in parts of India, Asia and Australia and feed on all animals they can get their teeth in to, which includes sharks if they get the chance.
They are great swimmers and can stay submerged for over an hour. By the mid-1960s, Saltwater crocodiles had nearly been hunted to extinction.
Today, the population is considered to be at low risk, but illegal hunting, habitat loss, and antipathy towards the species (due of its reputation as a man-eater) continue to put pressure on the population.
6.Whale Shark
Heading underwater, the largest living fish is the 40 ft (12 m) long Whale Shark. Weighing up to 24 US tons (22 tonnes)
they are an impressive sight, but despite their size, they feed mostly on tiny plankton. To put into scale how often they feed,
the Whale Shark can filter more than 1,400 gallons of ocean water per hour! Present in tropical seas around the world, whale sharks are considered vulnerable and are hunted in some areas.
Not only are they large, but they live long too! The Whale Shark is known to survive up to 150 years of age
5.Brown Bears and Polar Bears
The position of largest living land carnivore is shared between Brown Bears and Polar Bears. Weighing up to 700 kg and reaching up to 10 ft (3 m) tall when standing on their hind legs,
While you’ll find Brown Bears in the forests and mountains of North America, Europe and Asia,
you need to head further north to the Arctic Circle to catch a glimpse of Polar Bears, who split their time between the sea and ice and feed mostly on seals.
Bears have excellent senses of smell, sight and hearing.
They can smell food, cubs, a mate or predators from miles away. Their great eyesight allows them to detect when fruits are ripe.
4.Giraffe
At a height of 19 ft (5.8 m), the Giraffe is the tallest living animal on Earth, can weigh up to 1,930 kg (4,250 lb) ; the neck alone is 6 ft (1.8 m) tall.
Giraffe tongues are long, reaching around 20–21 in (50–53 cm) in length. At home in grasslands of East Africa, they feed mostly on vegetation high off the ground,
using their long prehensile tongues to pull young shoots and leaves from the trees. Babies are born after a 15 month gestation period and are already 2 m tall.
Male giraffes use their necks for fighting, swinging them from side to side to headbutt their opponent.
Giraffes have one of the shortest sleep requirements of any mammal, and will only sleep for around four hours a day.
3.African Elephant
The largest living land animal is the African Elephant which can weigh up to 6,350 kg; they typically grow to 35 ft (10.6 m) from trunk to tail and have a shoulder height of 13 ft (4.2 m).
There are at least two species, the savanna elephant and the forest elephant, and they currently cited as venerable in the IUCN Red List of Threatened Species.
Elephants live and travel in groups which are led by a matriarch female who tends to be an older and experienced member of the group.
Males however, are pushed out of the group when they reach sexual maturity and roam alone when not breeding.
Female Elephants are known to show caring behaviour to fellow females and young calves. They are also thought to hold lifelong relationships with family and friends, just like humans do.
colossal squid
The size of the colossal squid is often exaggerated, with viral posts on the internet saying they can reach 60 ft (18 m) or even 90 ft (27 m) in length!
However, the largest squid documented was 43 ft (13 m) long, and may have weighed nearly a ton. They have the largest eyes in the animal kingdom, reaching 10 in (25 cm) in diameter.
They eat small and large fishes and other squids. Their tentacles are covered with suckers that are equipped with strong, sharp hooks, used in both capturing prey and fighting off predation.
Sperm whales are the only known predator of the colossal squid.
olossal Squid live at depths of around 1000m, making it difficult to observe them in their natural habitat.
1.Blue whale
The Blue whale is the largest animal of all time, reaching a weight of about 180 tonnes and a length of 98 ft (30 m).
Their tongues alone can weigh as much as an elephant and their hearts as much as a car, yet they survive by eating a diet rich in tiny plankton.
A single adult blue whale can consume 36,000 kg of krill a day. Incredibly, Blue Whales are graceful swimmers cruise the ocean at over 8km/h, and can reach speeds of over 30km/h.
They mainly catch their food by diving, and descend to depths of approximately 500 m.
Blue whales have few predators but are known to fall victim to attacks by sharks and killer whales, and many are injured or die each year from impacts with large ships.
It is estimated that only 10,000-25,000 blue whales now swim the world’s oceans.
