Arctic tern, sooty shearwater, Bar-tailed godwit, or leatherback sea turtle are thes pecies with longest migratory in natural history.
The Arctic terns are the strongest migratory birds among migratory birds, their migratory distance is approximately 100.000km withthe route from Europe to Antarctica and vice versa. The Arctic terns are also the birds receiving the most daylight; they pass two summers each year because they travel a long distances from continent to continent.
The Arctic terns have a speed of about 250 km / day, they do not fly straight like other birds, instead of that, they fly around to take advantage of wind power, lifespan of the Arctic terns is about 30 years, during their lifetime, they will fly about 2.5 million km in total being equivalent to about 3 rounds moving from Earth to Moon and vice versa.
Sooty shearwaters live mainly in Snares Island, in the breeding season from November to April, their population is about 3.5 million individuals. They migrate about 64,000 km and the roadmap starts from New Zealand to Alaska, USA and vice versa.
Their main food is small animals such as shrimp, crabs, snails, shrimp, etc. According to the record of the Midway Atoll Wildlife Sanctuary, USA, this bird can live up to 70 years old with normal reproduction activities.
LEATHERBACK SEA TURTLE
In our thinking, turtle is considered asthe slowest species in the world, however, as opposed to that, leatherback sea turtle, also known as leatherback turtle, is the biggest sea turtle and the third big species among the reptile ones,following alligators.

The dragonfly is known for about 4,500 species, which belong to the insect order and are classified as incomplete metamorphosis. At the beginning of life cycle, the dragonflies are called nymph living in water, when growing up, they live on ground, so you often see that the adult dragonflies live near water environment such as lakes, streams and swamps.
Dragonflies use their legs to catch prey, they have large round heads and large double eyes on both sides supporting their better observation during flight and hunting. They are useful insects, and their food is mainly plant pests and mosquitoes. Their migration distance reaches 20,000 km, and the route starts from India to East Africa and vice versa.
Adélie penguins live extensively on the Antarctic coast, they build nests from stone and spawn from October to December every year on the coast of the Antarctic continent. Each reproduction time, they spawn only two eggs and incubates within 31-35 days, after hatching, the young ones will stay in the nest for about 25 days before beginning to practice for their new life.
The size range of Adélie penguins is from 45cm to 75cm, and the total body weight is between 3.5kg and 6.5kg. They emigrate about 13,000 km around the Ross Sea, after each migration and staying, their feces contribute to the melting of large amounts of ice at the settlement.
