Orphaned baby rhinos seen on August 28, 2014 in Lewa Wildlife Conservancy, Ngare Ndare Forest, Kenya. Lewa Wildlife Conservancy in Kenya is hand-raising three orphaned baby rhinos; Nicky, Hope and Kilifi. Baby rhino Hope was rescued by rangers when the poachers killed his mother – now he is been taken care off 24 hours-a-day at Lewa Wildlife Conservancy. The wildlife reserve hit the headlines when Prince William proposed to Kate Middleton there in 2010. Rhinos around the world are becoming extinct as a result of the brutal poaching fuelled by an illegal international market for their horns. (Photo by Luca Ghidoni/Barcroft Media)

Sheep walk as they are herded to summer pastures in Serra da Estrela, near Seia, Portugal June 27, 2015. In late June, shepherds young and old in the Seia region of central Portugal start guiding sheep, goats and cattle to the Serra da Estrela, the country’s highest mountains, in search of better pastures. There they stay until the end of September. Modern-day shepherds may have mobile phones to keep in touch with family and friends, but their lifestyle has changed little for centuries. The sound of cowbells and the bark of longhaired mastiffs starts early in the morning as the animals – often decorated with traditional woollen balls on their horns – are herded up steep, narrow paths.

“Chameleons (family Chamaeleonidae) are a distinctive and highly specialized clade of lizards. They are distinguished by their parrot-like zygodactylous feet, their separately mobile and stereoscopic eyes, their very long, highly modified, and rapidly extrudable tongues, their swaying gait, the possession by many of a prehensile tail, crests or horns on their distinctively shaped heads, and the ability of some to change color. Uniquely adapted for climbing and visual hunting, the approximately 160 species of chameleon range from Africa, Madagascar, Spain and Portugal, across south Asia, to Sri Lanka, have been introduced to Hawaii, California and Florida, and are found in warm habitats that vary from rain forest to desert conditions”. – Wikipedia

In Dougie Wallace’s photos of Mumbai taxis, the chatter, yelling, and constant horns of the city are almost audible. A selection of his images is on show at Gayfield Creative Spaces, Edinburgh, as part of the Retina photography festival until 30 July. For four years, the Glasgow-born Wallace focused his photos on one kind of taxi in particular: the Premier Padmini, a 1960s workhorse painted in black and yellow. Locally known as “Kaali-Peeli”, there were once more than 60,000 of them in the Indian city. But thanks to laws restricting pollution, the cars now are fast disappearing from Mumbai’s streets.

“Tardigrades (commonly known as waterbears or moss piglets) are small, water-dwelling, segmented animals with eight legs. Tardigrades were first discovered in 1773 by Johann August Ephraim Goeze, who called them kleiner Wasserbär, meaning “little water bear” in German. The name Tardigrada means “slow walker” and was given by Lazzaro Spallanzani in 1777. The name water bear comes from the way they walk, reminiscent of a bear's gait. The biggest adults may reach a body length of 1.5 millimetres (0.059 in), the smallest below 0.1 mm. Freshly hatched tardigrades may be smaller than 0.05 mm”. – Wikipedia. Photo: Tardigrades.

“We take rusty old junk and we put love into it”. The old Motor City has a unique style in bicycles these days: from fat wheels and fake fuel tanks to stretched cycles with powerful sound systems – and even a family-sized BBQ. “Detroit’s custom bike scene developed alongside Slow Roll, a weekly cycle ride started in 2010 by Jason Hall and Mike MacKool. Now upwards of 2,000 people turn up each Monday to cruise a different part of the city. The week I go the crowd seems evenly split between black and white, male and female, city and suburbs. It’s the most inclusive cycle event I’ve ever witnessed”. (Photo by Jason Walker/Slow Roll Monday Nights)
