10 most exotic types of animals

Humpback whale

These creatures are holding the world record for the longest journey of mammals. Each year, they spend warm summers to delight in eating a ton of food every day in the waters of Antarctica. When winter comes, they swim 8,000 km up the feeding grounds near Columbia and the equator.

Freshwater fish show

Freshwater fish is born to face rough, dangerous waters. After hatching in the salty waters of the Sargasso Sea, they swam to freshwater rivers in England and the East Coast of North America. On the way, their kidneys adapt to changes in salinity. By the time of spawning, these fish will return to the starting place.

Long neck cranes

Efforts to restore the population of long necked cranes include teaching flying lessons for this rare white bird. Robots controlled by radio and ultralight aircraft are disguised as cranes that have led them to fly south to conservation zones.

Queen Butterfly

The journey of deep migration migrates into the blood of princess butterflies. Every fall, thousands of children head west toward California and Mexico. They float over 4,500 km, through the United States and Canada. But how they know the place and time to start is still difficult to understand for scientists.

Red throat hummingbird

Before starting the 800 km journey to Central America, red throat hummingbirds with honey, insects and tree waxes. These tiny organisms weigh 2 grams more fat, almost double their body weight, and begin a non-stop flight from eastern North America across the Gulf of Mexico.

Salmon

After years of swimming in the sea, salmon follow their sense of smell to return to freshwater streams where they were born and eventually die there. They swim upstream against hundreds of miles of water to return home safely, even if that means they will arrive in a state of exhaustion.

Green turtle

Maternal instincts motivate female green turtles to return to their birthplace to start their own families. Pregnant belly turtles swim for more than 1,000 miles from the coastal feeding grounds in Brazil to the middle of the South Atlantic Ocean, to Ascension Island. On this sand, prospective mothers dig up nests and lay eggs before flipping back home.

Antelope

The green grass fields attracted more than 1.5 million of these herbivores, concentrating into a giant herd of Serengeti plains, along with thousands of zebras and gazelles, going more than 1000 km away to avoid the hot dry in Tanzania and Kenya.

Lemem mouse

In the Arctic moss, overcrowding and hunger have led them to migrate into large flocks at high speed. Researchers have recorded these tiny creatures running nearly 16 kilometers a day. For weak animals, the movement speed is too fast and they lag behind until death.

Cicada

This month, billions of chubby, humming cicadas will all crawl from the ground to gather, sing and marry. This insect has spent 17 years hiding in the ground, growing in 5 stages. Their exposures will overwhelm predators, and make many children have a chance to survive for 5 weeks to mature later.
