The Twelve Apostles is a collection of limestone stacks off the shore of the Port Campbell National Park, by the Great Ocean Road in Victoria, Australia.
The apostles were formed by erosion: the harsh and extreme weather conditions from the Southern Ocean gradually eroded the soft limestone to form caves in the cliffs, which then became arches, which in turn collapsed; leaving rock stacks up to 45 metres high.
The site was known as the Sow and Piglets until 1922 (Muttonbird Island, near Loch Ard Gorge, was the Sow, and the smaller rock stacks were the Piglets); after which it was renamed to The Apostles for tourism purposes.
The formation eventually became known as the Twelve Apostles, despite only ever having nine stacks.
The viceroy butterfly appears similar in color and pattern, but is markedly smaller and has an extra black stripe across the hind wing.
The eastern North American monarch population is notable for its annual southward late-summer/autumn migration from the United States and southern Canada to Mexico.
During the fall migration, it covers thousands of miles, with a corresponding multi-generational return North.
The western North American population of monarchs west of the Rocky Mountains most often migrate to sites in California but have been found in overwintering Mexico sites Monarchs were transported to the International Space Station and were bred there.
It dives from the sky in a daring plunge, snagging other airborne birds in mid-flight with its deadly talons.
Its body is the epitome of aerodynamic design, allowing it to reach—and survive—speeds that would kill other animals.
As it reaches its terminal velocity of over 200 mph, baffles in its nostrils prevent the force of the air from exploding its lungs—a feature that has been incorporated into jet engine design—and nictitating membranes on its eyes protect them from debris.
It snags its hapless victims in its talons, ending their terror with a killing blow from its deadly-sharp beak.
