Just got samples from the Arctic in August. So far, odd! The little tintinnid ciliate species ruled the summer. Plus, there seems to be for the USA - good day!

Victor Hensen coined the term "Plankton" in 1887. By 1910 it was an industry (still is)! Steuer's book ran 722 pages!

Yes they exist! Not many species but sometimes they can be abundant. They don't have the ornate lorica of many marine types and most are also relatively small (ca. 100 Β΅m long). Pic is Tintinnidium fluviatile from FaurΓ©-Fremiet (1924).

Never tire of looking at the wee bugs in the 1828 print by William Heath. Pretty sure some protists are in there. Look carefully - you'll find what you're looking for! #protistsonsky

AI image generators still do not know what a tintinnid ciliate of the marine plankton is - safe for the moment, can not quite yet replace me... #protistsonsky
