“How does a bear behave when encounter a human? In most cases he runs away. But before running he almost always would rise to stand on his rear feet. And this behavior does not indicate the attack, as many people think...” – Igor Shpilenok. (Photo by Igor Shpilenok via Wildlife Photo Russia)

“The frilled shark (Chlamydoselachus anguineus) is one of two extant species of shark in the family Chlamydoselachidae, with a wide but patchy distribution in the Atlantic and Pacific Oceans. This uncommon species is found over the outer continental shelf and upper continental slope, generally near the bottom though there is evidence of substantial upward movements. It has been caught as deep as 1,570 m (5,150 ft), whereas in Suruga Bay, Japan it is most common at depths of 50–200 m (160–660 ft). Exhibiting several “primitive” features, the frilled shark has often been termed a «living fossil»”. – Wikipedia

The frill shark, also known as a Frilled shark usually lives in waters of a depth of 600 meters and so it is very rare that this shark is found alive at sea-level. It's body shape and the number of gill are similar to fossils of sharks which lived 350,000,000 years ago. (Photo by Awashima Marine Park/Getty Images)

In this October 14, 2013 photo, ecology professor Ricardo Freitas catches a broad-snouted caiman to examine, then release back into the water channel in the affluent Recreio dos Bandeirantes suburb of Rio de Janeiro, Brazil. Caimans are like tanks, a very old species with a remarkable capacity for renovation that allows them to survive under extreme conditions where others couldn't, said Freitas, who runs the Instituto Jacare, or the Caiman Institute, which aims to protect the reptiles.

“Doctor fish is the name given to two species of fish: Garra rufa and Cyprinion macrostomus. Other nicknames include nibble fish, kangal fish, physio fish and doctorfishen; in non-medical contexts, Garra rufa is called the reddish log sucker. They live and breed in the outdoor pools of some Turkish spas, where they feed on the skin of patients with psoriasis. The fish are like combfishes in that they only consume the affected and dead areas of the skin, leaving the healthy skin to grow, with the outdoor location of the treatment bringing beneficial effects. The spas are not meant as a curative treatment option, only as a temporary alleviation of symptoms, and patients usually revisit the spas every few months”. – Wikipedia

Customers sit with their feet in a tank filled with 100-150 Garra Rufa fish which remove any dead skin by nibbling and sucking. A half hour session is then followed by a foot massage.

MS Tûranor PlanetSolar, known under the project name PlanetSolar, is the largest solar-powered boat in the world The vessel was designed by LOMOcean Design, built by Knierim Yachtbau in Kiel, Germany, and launched on 31 March 2010. In May 2012, it became the first ever solar electric vehicle to circumnavigate the globe. The 31-meter boat is covered in over 500 square meters of solar panels rated 93 kW, which in turn connect to one of the two electric motors in each hull. There are 8.5 tons of lithium-ion batteries in the ship's two hulls. The boat's shape allows it to reach speeds of up to 14 knots. The hull was model tested in wind tunnels and was tank tested to determine its hydrodynamics and aerodynamics. The boat has been designed to be used as a luxury yacht after the record attempt is finished.
