Annual Red Crab Migration On Christmas Island

          Annual Red Crab Migration On Christmas Island

At the beginning of the wet season (which is usually October / November), over 50 million adult red crabs suddenly start migrating from the forest to the coast to breed. The migration is usually synchronized all over the island. The males lead the first wave of the migration and are joined byfemales as they progress. The crabs take about five to seven days to reach the sea. The rains and moist overcast conditions make their journey to the sea long and difficult.

During peak migration times, sections of roads where crabs cross in high numbers are closed to vehicles for short periods of time. The bright red carapaces and sheer density of crabs make their routes to the sea observable from the air.

After mating the females release their eggs into small burrows on the sea where the hatch, and the young larvae develop into tiny small crabs. After remaining about a month in the ocean, the young crabs, only five millimeters across, accompanied by the adults make their long trek back home. Upon reaching the inland, the crabs disappear into rocky outcrops, fallen tree branches and debris on the forest floor for the next three years.

Human activities have led to increased numbers of red crabs being killed during their annual migration. The crabs risk dehydration when they are forced to cross areas cleared of forest cover and many thousands of adults and young are crushed by vehicles as they cross the roads. To protect the crabs from being crushed by vehicles, staff of Christmas Island National Park some roads are also temporarily closed off and crab crossing signs erected at places. Walls andplastic fencing along the roads are also built to funnel the crabs to the 'crab crossings' and 'crab bridges' where they may safely cross.

The crab migration and the crab bridges have become a great tourist attraction.

Worlds First Solar Plant That Generates Power At Night

The new Gemasolar Power Plant near Seville in southern Spain is the world’s first solar plant to have the capacity to generate electricity even at night. More than 2600 concentrically arranged mirrors spread across 185 hectares of rural land concentrate solar energy towards a centrally located molten nitrate salt tank. As the rays converge, they super-heat the salt to over 900C, causing water around the tank to boil and drive steam turbines. In addition, any superfluous heat generated during the day is stored within the liquefied salt. It acts like a giant thermal battery for driving the turbines at night and during overcast days up to 15 hours at a time with no sunlight. But Seville, being one of the sunniest areas in Europe, this doesn’t happen very often.
The $US410 million Gemasolar plant that just opened has a potential output of 20 megawatts, though it is currently operating below that capacity. Officials expect it could reach 70 per cent capacity by 2012. It’s the largest solar power station of its type in Europe, and it has an annual production total or roughly 110 GWh/year — enough to power 25,000 homes and reduce atmospheric CO2 emissions by more than 30,000 tons a year. The project, a joint venturebetween Abu Dhabu energy company Masdar and Spanish engineering firm SENER called Torresol Energy, took two years to construct at a cost of £260million.

Daredevil Rope Free-Climber Spiderman

Daredevil Rope Free-Climber Spiderman 
Don't let go! Heart-stopping moment 'Spiderman' free-climber dangles over 500ft cliff with no ropes



This is the heart-in-mouth moment a daredevil climber dangles over the edge of a 500ft cliff without any ropes.

Mich Kemeter is a world expert at free solo climbing, a discipline where participants forgo essential safety equipment in search of that extra adrenaline rush.

The 23-year-old was pictured in the Verdon National Park, France, by mountain adventure photographer Alexandre Buisse, who takes extra care not to put him off in case he falls to his death.

Amazing Monkey And His Dog







Amazing Monkey And His Dog One monkey and his dog: Primate rounds up sheep at the rodeo, on the back of a border collie

They are an inseparable double act – Bud the border collie and Whiplash the Capuchin monkey.


What’s more, there’s nothing they like better than rounding up sheep – to the delight of the crowds at the rodeo in Reno, Nevada.

Whiplash, 27, is now a favourite at the rodeos in the US south-west.
