Swimmers from around the world plunged into the salty waters of the Dead Sea on Tuesday to attempt a seven-hour swim across the fabled lake in a bid to draw attention to its environmental degradation. Wearing protective masks and snorkels, 25 swimmers paddled through the muddy water to attempt the 9-mile (15-kilometer) swim from Jordan to Israel. (Photo by Nir Elias/Reuters)

The red-footed booby is the smallest of all boobies at about 70 centimetres (28 in) in length and with a wingspan of up to 1 metre (3.3 ft). It has red legs, and its bill and throat pouch are coloured pink and blue.

“The Red River Hog (Potamochoerus porcus), also known as the Bush Pig (but not to be confused with P. larvatus, common name “Bushpig”), is a wild member of the pig family living in Africa, with most of its distribution in the Guinean and Congolian forests. It is rarely seen away from rainforests, and generally prefers areas near rivers or swamps.

Red River Hogs eat grass, berries, roots, insects, molluscs, small vertebrates and carrion. They are capable of causing damage to plantations. Red River Hogs typically live in herds of 6-20 members led by a dominant boar. Sows rear 3-6 piglets at a time.”

This graceful husky appears to be smarter than your average dog having apparently mastered the art of walking on water. The soft-footed canine was photographed while making its way across a lake in northern Russia. Photographer Fox Grom captured a remarkable set of images after heavy rain fell on a frozen lake to create the amazing illusion. The 40-year-old, who works as an all-terrain vehicle driver, regularly walks his pet dogs, Alaska and Blizzard, near the natural beauty spot. “I always take pictures of my dogs whilst walking them but on this occasion there was an extraordinary phenomenon“, he said. “The ice was already very thick when it rained heavily making for a spectacular scene”.
