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!

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 µm long). Pic is Tintinnidium fluviatile from Fauré-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
