Top 10 Oldest Living Organisms in the World
Oldest living organism Brazilians is something interesting for us to talk about. These organisms have lived for a long time even millions of years. They have achieved excellence in their neighborhoods clear. Here is a list of oldest living organisms in the world.
10. Martialis Heureka – 120 Million Years
Martialis Heureka ranks tenth as the oldest living organisms. Only discovered in 2000 in Amazon, this ant species known as the Ant from Mars. Resembling a miniature wasp, the insect does not like other ants, and is the oldest ant species that still inhabit the earth. What makes it truly amazing is that the genetic code showed it was among the first sub-family to break away from the main lineage, soon after the ants evolved from wasps more than 120 million years ago.
9. Sturgeon – 200 Million Years
Sturgeon is ranked ninth as the oldest living organisms. Sturgeon is the common name of the 26 species in the family Acipenseridae, including the genus Acipenser, Huso, Scaphirhynchus, and Pseudoscaphirhynchus. Sturgeon is the oldest families of bony fish are still alive, they are native to rivers, lakes, and beaches in the subtropical, temperate, and subarctic throughout Eurasia and North America.
8. Horseshoe Shrimp – 200 Million Years
Shrimp Horseshoe ranked eighth as the oldest living organisms. This little guy has the distinction of being the oldest living species on earth unchanged for 200 million years. In other words, he might not have been around for a few people on it, but he is virtually indistinguishable from the 200 million year old fossils.
7. Ginkgo Biloba – 270 Million Years
Ginkgo Biloba is ranked seventh as the oldest living organisms. Ginkgo (Ginkgo biloba) is one of the single species of seed plants open divisio member ever widespread in the world. At present the plant is known to grow wild only in Northeast Asia, but has been widespread in many other temperate places as an ornamental tree garden or yard. Form of modern plant has not changed much from his fossils were found. Potential seeds of a large seeds may also have influenced this decline, in line with the fossil record.
6. Coelacanth – 360 Million Years
Coelacanth is ranked sixth as the oldest living organisms. Coelacanth is the name of the order (nation) of fish among others consisting of an evolutionary branch of the oldest living jawed fish. Coelacanth is estimated to have gone extinct since the late Cretaceous period 65 million years ago, until a specimen was found in eastern South Africa, in the waters of the river Chalumna 1938.
5. Horseshoe Crab – 445 Million Years
Horseshoe Crab is ranked fifth as the oldest living organisms. The Horsehoe crab remained pretty much unchanged since the Ordovician period. So, it exists on Earth about 74% of the time that animals in general have. Early species of horseshoe crabs crawling around the earth’s shallow coastal seas for at least 100 million years before dinosaurs even arrived.
4. Sponge – 580 Million Years
Sponge ranked fourth as the oldest living organisms. Sponges are an ancient group of animals genealogy can be traced back to the beginning of animal life. Glass sponge fossils have been found from about 540 million years ago in rocks in Australia, China and Mongolia. Although about 90% of modern sponges demosponges, fossils of this type is less common than other types because their skeletons are composed of relatively soft sponge that does not fossilize well.
3. Jellyfish – 505 Million Years
Jellyfish is ranked third as the oldest living organisms. The jellyfish is included in the group of animals called Cnidaria or Coelenterate. This group includes corals, hydras, jellyfish, Portuguese man-of-war, sea anemones, sea pens, sea whips and sea fans. They are difficult to fossils, which are mostly made of water, but a few years ago some new fossils were found which makes them even older than previously thought. The jellyfish is included in the class Scyphozoan. Tufted umbrella-shaped body, can make the itching of the skin upon contact.
2. Nautilus – 500 million years
Nautilus is ranked second as the oldest living organisms. Is the common name for several species of marine mollusks that goes is the Nautilidae family. Although shelled, Nautilus is still related to squid and octopus. Animals that can have 90 tentacles and a diameter of 3 and 30 cm are known to have lived since millions of years ago with a form that does not change much, so it is considered living fossils.
1. Cyanobacteria – 3.8 billion years
Cyanobacteria are the oldest living organism ever. Cyanobacteria, also known as blue-green bacteria, blue-green algae (Cyanophyceae), as well as blue algae, are a phylum (or division) bacterial photosynthetic autotrophy. Trace fossils have been found to 3.8 billion years old. This bacterial group now is one of the largest and most important groups on Earth. With fossils 3.8 billion years old, Cyanobacteria are the oldest living organism.
