Respect, Kronotsky nature reserve, Russia. The photographer’s cat, Ryska – her name means little lynx in Russian – stands outside their cabin and with aggressive posturing warns off a fox. In winter, foxes would regularly visit the cabin searching for food. If one peered in at the window, possible when the snow was deep, Ryska would sit on the other side, fur raised, and growl. When outside, she would hold her ground. The foxes were not always frightened and so encounters could be a sort of dance. (Photo by Igor Shpilenok/Unforgettable Behaviour/NHM)

Artists called “Le couple en chocolat” take part in the festival “Statues en Marche” in Marche-en-Famenne, Belgium, July 22, 2018. Living statues are a common sight in many city centres, but it is rare to see such a diverse range of this peculiar form of street art for which performers must keep still for painfully long periods of time to create the desired illusion.

Undated image released Monday February 17, 2020, by Irish Coast Guard showing the abandoned cargo ship MV Alta, that has washed up on the coast of County Cork, near Ballycotton, southern Ireland. The MV Alta is believed to have had 10 crew members aboard who were rescued by the US Coast Guard. Since September 2018, the ship has been drifting with no crew aboard, and it was last seen off the coast of West Africa before being washed up in southern Ireland during Storm Dennis.

Among the fish populations that could be harmed by the Xayaburi dam in Laos is the critically endangered Mekong giant catfish, considered by the Guinness Book of World Records to be the world’s largest freshwater fish. The fish, which grows to 650 pounds and about 10 feet long, is only found in the Mekong River. It is migratory, moving between downstream habitats in Cambodia upstream to northern Thailand and Laos each year to spawn. Some experts fear the Xayaburi dam could block the migration and drive the giant catfish to extinction. (Photo by Courtesy of Zeb Hogan/University of Nevada, Reno)

A baby turtle's perilous first moments are captured as it takes to the sea for the first time on Heron Island in Queensland, Australia in July 2022. Predators such as sharks, birds, and pollution mean that approximately only one out of every 1000 turtles that hatch make it to adulthood, with some not even reaching open ocean.
