tripsis Posted November 21, 2013 (edited) Hibiscus flowering after being coated in ash shortly after the recent eruption of Mount Sinabung in Sumatra. The next images are micrographs of radiolarians. The Radiolaria are protozoans within the kingdom / supergroup Rhizaria, so far removed from us on the phylogenetic tree of life that it blows my mind. Radiolarians, which only measure 0.1 - 0.2 mm, are found throughout the ocean and build a morphologically diverse range of silaceous skeletons, which is what you are looking at in the micrographs. Many radiolarians symbiotically host zooxanthellae, in the same way that corals do. Embryonic Prasinohaema flavipes.Species within the genus of skinks Prasinohaema are known for their remarkable lime-green blood, tissues and bones. This unusual colouration is a result of exceptionally high levels of the pigment biliverdin, a breakdown product of haemoglobin (which is what you are seeing when your bruises take on a yellow-green colouration). In most animals, levels of bilirubin in the blood this high would be fatally toxic, yet it is thought that skinks in the genus Prasinohaema have evolved to tolerate elevated levels of biliverdin as they may confer protection against the Plasmodium parasite, the cause of malaria.

tripsis Posted November 23, 2013 The Great Arch of China, in Getu River National Park. I hope to be climbing there within the next four years. See the Youtube vid thread for the video. Worth watching even if you're not into rock climbing. 5 Share this post Link to post Share on other sites
