Bamboo bear

Iconic black-and-white bear of the mountain bamboo forests of central China, giant pandas can weigh up to 125 kg and spend up to 14 hours daily consuming bamboo, which comprises 99% of their diet despite belonging to the order Carnivora. Solitary and elusive, they have a pseudo-thumb for gripping bamboo stems. Downgraded from Endangered to Vulnerable in 2016 following successful conservation and breeding programs.

Chrysochromulina brachycylindra is a species of unicellular haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae. The specific epithet brachycylindra refers to a morphological feature — likely a short cylindrical element of the cell's scale or haptonema structure — distinguishing it from related species. Chrysochromulina species are marine nanoplankton organisms covered in species-specific organic or mineralized scales, which together with haptonema length, flagella structure, and cell dimensions provide the principal characters for species delimitation. C. brachycylindra has been recorded from Norwegian coastal marine environments, part of the extensive northern European haptophyte fauna documented through electron microscopy surveys. Norwegian fjords and coastal shelf waters offer cold, seasonally productive conditions that support diverse haptophyte assemblages, with Chrysochromulina species often dominating nanoplankton communities during spring and summer stratification. The species is presumed to be photoautotrophic or mixotrophic, acquiring carbon both through photosynthesis using chlorophylls a and c and fucoxanthin-like accessory pigments, and potentially through ingestion of bacteria or small organic particles. Notable Chrysochromulina blooms in Norwegian waters have historically caused damage to fish farms, though C. brachycylindra specifically has not been implicated in harmful bloom events. The species carries a conservation status of Not Evaluated under IUCN criteria, as microalgal plankton taxa in this size class are not routinely assessed for extinction risk given their broad dispersal potential and microscopic nature.
