10 Biggest Living Things on Earth

Many people find it difficult to grasp life in all its diversity: not only the birds, reptiles and mammals that everyone knows and love, but also viruses, bacteria, protists, invertebrates, and trees and fungi. On the following images, you'll go on a guided tour of the biggest organisms on Earth, ranging from a giant (by microscopic standards) virus, to a gigantic (by anyone's standards) clonal colony of trees — with all your favorite whales, elephants, and anacondas in between.

Here are some of the largest living things on Earth, ranked by size:

The Great Barrier Reef - 

The Great Barrier Reef is a vast system of coral reefs, islands, and cays located in the Coral Sea, off the coast of Queensland, Australia. It is the world's largest coral reef system, stretching for over 1,400 miles (2,300 km) and covering an area of approximately 133,000 square miles (344,000 square km).

The Great Barrier Reef is home to an incredibly diverse array of marine life, including over 1,500 species of fish, 600 species of coral, and numerous other species of marine animals, such as sea turtles, dolphins, sharks, and rays. It is also an important breeding ground for many species of birds.

However, the Great Barrier Reef is under threat from various human activities, including climate change, pollution, and overfishing. These threats have led to coral bleaching, where corals expel the algae that live within their tissues, which can lead to the death of entire coral colonies. The Australian government and conservation organizations are working to protect and preserve the reef, but it remains a significant environmental concern.

Pando -

 Pando is a clonal colony of quaking aspen trees located in central Utah, USA. It is considered to be one of the largest living organisms in the world, covering an area of approximately 106 acres (43 hectares) and weighing an estimated 6,000 tons.

Pando consists of thousands of individual trees that are genetically identical and connected through a common root system. The trees reproduce asexually by sending up new shoots from the roots, which grow into mature treated to be between 80,000 and 1 million years old, making it one of the oldest living organisms on the planet.

 However, Pando is currently under threat from human activities, such as grazing by deer and elk, which can prevent new growth and damage the root system. Conservation efforts are underway to protect and preserve Pando, including the establishment of a protected area and the use of fencing to control grazing.

Blue whale - 

The blue whale (Balaenoptera musculus) is the largest animal on Earth, with adults reaching lengths of up to 100 feet (30 meters) and weighing as much as 200 tons. Blue whales are found in oceans around the world, and they are known for their distinctive bluish-gray color and long, slender bodies.

Blue whales are baleen whales, which means that they feed by filtering tiny organisms, such as krill and plankton, through baleen plates in their mouths. They can consume up to 4 tons of krill per day during feeding season.

Blue whales are classified as endangered due to whaling activities that significantly reduced their populations in the 20th century. However, since the International Whaling Commission banned commercial whaling in 1986, their populations have slowly started to recover. Despite these conservation efforts, blue whales continue to face various threats, including collisions with ships, climate change, and ocean noise pollution.

Giant squid -  

The giant squid (Architeuthis dux) is a deep-sea dwelling cephalopod that is one of the largest invertebrates on the planet. They are known for their massive size and elusive nature, as they inhabit the deep ocean and are rarely encountered by humans.

Giant squid can grow to lengths of up to 43 feet (13 meters) and weigh as much as 600 pounds (270 kilograms), although the size of most specimens is much smaller. They have a large, torpedo-shaped body, 8 long arms lined with suckers, and two longer tentacles that they use to capture prey, such as fish and other squid.

Due to their habitat in the deep ocean, very little is known about the biology and behavior of giant squid. They have been the subject of myth and legend for centuries, and only a few live specimens have ever been captured on camera.

 However, advancements in technology and exploration have allowed for more frequent sightings and a better understanding of these fascinating creatures.

Despite their elusiveness, giant squid face various threats from human activities, such as deep-sea fishing, oil and gas exploration, and plastic pollution. Conservation efforts are underway to protect these mysterious creatures and their deep-sea habitats.

African elephant -

The African elephant (Loxodonta africana) is the largest land animal in the world and is found in various habitats across Africa, including savannas, forests, and deserts. They are known for their long trunks, large ears, and tusks that can grow up to 10 feet (3 meters) long.

African elephants are social animals that live in family groups called herds, which are led by a matriarchal elephant who is usually the oldest and most experienced female in the group. They are herbivores and can consume up to 300 pounds (136 kg) of vegetation per day, using their trunks to gather food and water.

African elephants face numerous threats from human activities, including habitat loss, poaching for their ivory tusks, and human-elephant conflict. They are classified as vulnerable by the International Union for Conservation of Nature (IUCN) due to these threats, and conservation efforts are underway to protect their habitats and reduce human-elephant conflict. These efforts include anti-poaching patrols, creating protected areas, and promoting coexistence between elephants and humans.

Giraffe - 

The giraffe (Giraffa camelopardalis) is an iconic African mammal known for its incredibly long neck and distinctive spotted coat. They are the tallest land animals in the world, with adult males reaching heights of up to 18 feet (5.5 meters) and females reaching up to 14 feet (4.3 meters).

Giraffes are herbivores and feed primarily on leaves and buds of trees, which they can reach with their long necks and prehensile tongues that can extend up to 18 inches (45 cm). They are social animals and live in loose herds, with males often engaging in "necking" fights to establish dominance.

Despite their unique characteristics, giraffes face various threats from human activities, including habitat loss, poaching for their meat and hide, and civil unrest in some areas of Africa. 

According to the International Union for Conservation of Nature (IUCN), giraffes are currently classified as "vulnerable" due to these threats, and conservation efforts are underway to protect their habitats and prevent further population decline. These efforts include anti-poaching initiatives, community-based conservation programs, and protected areas for giraffes to thrive.

Saltwater crocodile - 

The saltwater crocodile (Crocodylus porosus) is the largest living reptile in the world, with adult males reaching lengths of up to 23 feet (7 meters) and weighing as much as 2,200 pounds (1,000 kilograms). They are found in the saltwater and freshwater habitats of Southeast Asia and Australia.

Saltwater crocodiles are apex predators and have a reputation for being extremely aggressive and dangerous to humans. They have powerful jaws and sharp teeth, which they use to catch a variety of prey, including fish, birds, and mammals.

Saltwater crocodiles have been hunted for their skin and meat in the past, leading to significant population declines in some areas. However, conservation efforts have been successful in some regions, and saltwater crocodiles are now protected in many countries. Despite these efforts, they continue to face threats from habitat loss, human-wildlife conflict, and poaching.

Titan arum -

The Titan arum (Amorphophallus titanum) is a rare and unusual flowering plant native to the rainforests of Sumatra, Indonesia. It is known for producing one of the largest flowers in the world, which can grow up to 10 feet (3 meters) tall and 3 feet (1 meter) wide.

The Titan arum produces this massive flower only once every few years, and the bloom lasts for only a few days before collapsing. The plant also emits a foul odor, which is often compared to the smell of rotting meat, to attract pollinators such as flies and beetles.        World Dangerous Trees

The Titan arum is considered to be a vulnerable species due to habitat loss and over-harvesting of its seeds and tubers for use in traditional medicine. Many botanical gardens and conservation organizations are working to protect the species and raise awareness about its conservation status. 

Despite its size and rarity, the Titan arum has become a popular attraction in botanical gardens around the world, drawing crowds of visitors to witness its massive bloom and unique odor.

Giant sequoia -

The giant sequoia (Sequoiadendron giganteum) is one of the most massive trees in the world, found exclusively in California's Sierra Nevada mountain range. They can reach heights of up to 311 feet (95 meters) and have trunk diameters of up to 40 feet (12 meters), making them among the largest living organisms on Earth.

Giant sequoias are long-lived, with some trees living for over 3,000 years. They are also resilient, with thick bark that helps protect them from fires and disease. Giant sequoias are known for their impressive size, but they also play an important role in their ecosystem, providing habitat for numerous species and storing large amounts of carbon.

Despite their resilience, giant sequoias face threats from climate change, wildfires, and human activities such as logging and development. Conservation efforts are underway to protect and restore giant sequoia habitat, including prescribed burns to reduce the risk of catastrophic fires and creating protected areas for the trees to thrive.

Anaconda -

 The anaconda is a large and powerful species of snake found in South America, known for its impressive size and strength. There are four species of anaconda, with the green anaconda (Eunectes murinus) being the largest and heaviest snake in the world. They can grow up to 30 feet (9 meters) long and weigh over 500 pounds (227 kilograms).

Anacondas are non-venomous constrictors and feed on a variety of prey, including fish, birds, mammals, and reptiles. They are ambush predators and will wait for their prey to come close before attacking and constricting them with their muscular bodies.

Anacondas are a key predator in their ecosystems, but they are also threatened by habitat loss, poaching for their skins and meat, and human-wildlife conflict. They are listed as a species of "least concern" by the International Union for Conservation of Nature (IUCN), but some populations are declining, and conservation efforts are needed to protect them and their habitats.
