Chrysochromulina simplex is a haptophyte microalga in the family Prymnesiaceae, its specific epithet simplex (Latin: simple or plain) suggesting cells that lack elaborate ornamental scales compared with more complex congeners. Cells are biflagellate, bearing two unequal flagella and a haptonema of variable development. The cell surface, while bearing scales, may display less complex scale architecture than in other Chrysochromulina species. C. simplex inhabits marine and brackish coastal waters, with records from northern European seas including the coasts of Scandinavia. The genus Chrysochromulina is a major contributor to nanoplankton communities in cool, nutrient-enriched coastal waters, where haptophytes can dominate the phytoplankton biomass during seasonal stratification events. Mixotrophic capabilities documented in congeners allow flexible nutritional strategies in seasonally variable environments. The species has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Free-living marine protists with cosmopolitan tendencies are generally resilient to localized environmental disturbances, though global ocean changes such as warming and acidification may shift community composition over longer timescales.

Comoro Flying Fox

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
