Sugar gliders, Candy and Popcorn, enjoy their favourite food, Nectar, at Wild Life Sydney Zoo on February 14, 2017 in Sydney, Australia. The treat made up of honey, high protein baby cereal and egg yolks is the human equivalent to chocolate to the Sugar Gliders. St. Valentine's Day or the Feast of Saint Valentine began as a celebration of the early Christian Saint Valentinus. From the 18th Century onwards it has steadily transformed into a celebration of romantic love and sentiment in many countries around the world. (Photo by James D. Morgan/Getty Images)

These heart-warming photograph show an incredible bond between a wild lioness and the men fighting to save her species. The picture show Sirga – a 110lb lioness – and her adopted pride Valentin Gruener (not pictured) and Mikkel Legarth. Incredibly she treats the two men just like she would other lions and with their help she can now hunt for prey on her own. As a cub she was driven out from a pride and rescued by German and Danish duo Valentin and Mikkel who could not stand by and watch her die. She is now a beacon for hoped success of the Modisa Wildlife Project, founded in Botswana, Africa, by Valentin and Mikkel with the hope of saving the lion population. (Photo by Caters News)

“The Rothschild Giraffe (Giraffa camelopardalis rothschildi) is among the most endangered giraffe subspecies with only a few hundred members in the wild. It is named after the famous family of the Tring Museum's founder, Lord Walter Rothschild, and is also known as the Baringo Giraffe, after the Lake Baringo area of Kenya, or as the Ugandan Giraffe. All of those that are living in the wild are in protected areas in Kenya and Uganda. (Recently it has been proposed that the Rothschild Giraffe is actually a separate species from other giraffes and not a giraffe subspecies).” – Wikipedia

Dont get catty. These roar-some images show the moment two female tigers came to blows in a bitter dispute over territory. Rarely ever seen in the wild let alone on camera, the dramatic images show a white Siberian tiger and orange-coloured tiger slashing ferociously at each others face and eyes. The intense altercation erupted into violence when the smallest of the pair, the orange striped tiger known as Shadow, attempted to expand its hunting ground. But white tiger, TiBo, wasnt willing to give up the ground without a fight and was forced to use its size and weight to put Shadow firmly back in her place.

Woolland Woods, Dorset. Landscape photographer of the year 2020. “Taken in spring of 2018 in a wooded area close to Milborne St Andrew in Dorset, this was the third visit to the area in a matter of days. On the previous days, both devoid of morning mists, the light had been harsh and unappealing but the third day delivered stunning conditions with mist swirling through the trees. The low shooting position allowed more emphasis to be placed on the wild garlic and pathway”. (Photo by Chris Frost/UK Landscape Photographer of the Year 2020)
