Blue Wildebeest Migration Facts – Discover The World’s Largest Land Migration

blue wildebeest migration

The annual blue wildebeest migration in East Africa is the world’s largest land migration, and one of the most famous of all natural spectacles.

During their annual circular migration, huge herds of over a million blue wildebeest travel a distance of around 1,000 miles (1,600 km) in search of fresh grazing and water.

Challenges faced by the blue wildebeest during the journey include crossing crocodile-infested rivers and the continuous threat of predation by animals such as lions, hyenas and cheetahs.

When Did Humans First Appear On Earth?

when did humans first appear

Humans first appeared on Earth at least 315,000 years ago. This figure is based on fossil remains found in Jebel Irhoud, Morocco – the earliest-known remains of modern humans.

The exact time humans first appeared is difficult to judge because species don’t come into being overnight. Rather, they change and evolve slowly from ancestral species.

Because the first human remains date back to around 315,000 years ago, our species will therefore have appeared some time before this. DNA evidence from human chromosomes indicates that humans (scientific name: Homo sapiens) may have first appeared more than half a million years ago.

American Crocodile Facts, Pictures & In-Depth Information

American Crocodile Facts

The American crocodile is a large crocodilian in the family Crocodylidae (the “true crocodile” family). It is found in coastal and aquatic habitats in the warmer waters of North, Central and South America, as well as on Caribbean islands. The species shares part of its range with the similarly-sized American alligator.

Like other crocodilians, the American crocodile is an ambush predator. Rather than actively pursuing its prey, it lurks under the water waiting for unsuspecting animals to come within reach of its powerful jaws.

In many parts of its range the American crocodile was once hunted almost to extinction for both its meat and its hide. The species is now protected under national and international laws. Although no longer endangered, the American crocodile is still rated as “Vulnerable” by the International Union for Conservation of Nature.
