- n. Plural form of foraminiferan.
Sorry, no etymologies found.
By analysing oxygen isotope ratios in tiny marine creatures called foraminiferans preserved in sediments that were deposited at the bottom of the Red Sea, the scientists reconstructed past sea levels, which were corroborated by comparison with the fossilised remains of coral reefs.
Among many foraminiferans with an organic shell (or 'test'), they found four undescribed specimens with agglutinated tests.
The group it belongs to, the xenophyophores, is foraminiferans, and these often switch between sexual and asexual reproduction.
Until today, the seas have been calm enough that staring at tiny living creatures magnified 12 or 50 times in petri dishes full of deoxygenated water has been a hypnotic, through-the-rabbit-hole exercise: foraminiferans like frosted Christmas-tree ornaments, spaghetti worms like exploded dissections gone bad, snails wearing circa-1960 bathing caps with bobbing bacterial filaments, all amid a snow-globe blizzard of gold, mica, and dragonfly-iridescent flakes.
