The clear blue water off Sidmouth in Devon, UK in March 2025 turned an orangey-red hue as tonnes of 200 million-year-old sandstone was mixed in by the tide. The 500ft cliff suffered a massive fall in October last year, and took a large section of Otter sandstone and Mercia mudstone with it. (Phoot by Dean Penn/RedZepplin/Bournemouth News)

“Pilot whales are cetaceans belonging to the genus Globicephala. There are two extant species, the long-finned pilot whale (G. melas) and the short-finned pilot whale (G. macrorhynchus). The two are not readily distinguished at sea and analysis of the skulls is the best way to tell the difference between the two species. Between the two species, pilot whales range in waters nearly worldwide with long-finned pilot whales living in cooler waters and short-finned pilot whales living in warmer waters. Pilot whales are among the largest of the oceanic dolphins, exceeded in size only by the killer whale. They and other large members of the dolphin family are also known as blackfish”. – Wikipedia

“Hippo Chase”. As we approached the camp the Selinda Reserve of northern Botswana our boat passed by a hippo resting in the water. I turned around to look back at the boat's wake and saw the hippo charging after us! The hippo must've been tired from an all-nighter because he was angry. He rose way up out of the water three times trying to chase our boat! He was coming at us with such force that he created a wake of his own. Photo location: Selinda Reserve of northern Botswana.
