Red Kangaroo: Australia's largest native land mammal #amoty2022.
The red kangaroo (Osphranter rufus) is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial.
The largest whale (and largest mammal, as well as the largest animal known ever to have existed) is the blue whale, a baleen whale (Mysticeti). The longest confirmed specimen was 33.58 m (110.17 ft) in length and the heaviest was 190 tonnes.
The rhinoceros is the second-largest land mammal, behind the elephant. These stocky, Land Rover-sized vegetarians once numbered over 500,000, but they have been reduced to about 29,000 in recent years, largely due to humans' appetite for their signature appendage: the horn.
What is the blue whale? Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues alone can weigh as much as an elephant.
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
Elephants. Elephants, specifically African bush elephants, are the second largest animals in the world and the largest on land.
The largest land animal on earth currently is the African elephant. There have been animals far greater than an African Elephant in the 4 billion-year history of Earth, one of those is called Argentinosaurs. These are the world's biggest land creatures ever, that lived in what is now South America.
Octopuses and squids (animals called cephalopods) have three hearts. Two hearts pump blood to the gills to take up oxygen, and the other pumps blood around the body (Figure 1).

In brute strength, elephants are the strongest mammals and the strongest land animals. African elephants can weigh up to 6,350kg and they can carry up to 9,000kg, the weight of 130 adult humans.
The Megalodon weighs in at upwards of 50-70 tons, measuring a span of up to 60-70 feet in length. By contrast, the Blue Whale tips the scale at around 100-110 tons and tops lengths of up to 100 feet. Who Wins on Size? It's pretty obvious that the Blue Whale is the bigger apex predator in this fight.
AUSTRALIA IS home to some very large, charismatic birds. In fact, the emu is considered to be the second largest in the world, right after the ostrich.
More than 80% of our plants, mammals, reptiles and frogs are unique to Australia and are found nowhere else in the world. Some of our Australian animals are very well known like kangaroos, dingos, wallabies and wombats and of course the koala, platypus and echidna.
Causes of extinction. Many modern researchers, including Tim Flannery, think that with the arrival of early Aboriginal Australians (around 70,000~65,000 years ago), hunting and the use of fire to manage their environment may have contributed to the extinction of the megafauna.
Dreadnoughtus schrani is a newly discovered species of dinosaur and the biggest titanosaurian sauropod dinosaur found so far. It is the largest land animal who's body mass can be accurately calculated.
According to the BBC Science Focus, the smallest animal in the world is the Etruscan shrew. The Etruscan shrew, also known as the white-toothed pygmy shrew or Suncus etruscus, is located in North America.
6. Bats are the only flying mammal. While the flying squirrel can only glide for short distances, bats are true fliers. A bat's wing resembles a modified human hand — imagine the skin between your fingers larger, thinner and stretched.
1. Steppe Mammoth. The steppe mammoth is the largest mammoth species to be discovered and is slightly bigger than an African elephant.
Three-toed sloths are some of the slowest and seemingly laziest creatures in the world. Instead of evolving to eat more, they evolved to do less.
Howler Monkeys: 128db
They are also known as the loudest land animal as their howls can reach up to 128 db and cover an area of 3 miles. They make these guttural and high pitched noises with the help of an enlarged hyoid bone.
