Five years later, I have my own lab. In Puerto Rico. And guess who's here!!! During one of our first lab field trips, we sampled a hypersaline shallow lagoon. Yes, Spirorhynchus was in there. Also by our dock. Trying to get in the lab?! We have welcomed him in and are interviewing his tufty friends!

One year later, in Beinart Lab @symbiosisrox.bsky.social, I got an incredible opportunity to join Joan Bernhard & Ginny Egdcomb on another cruise to SBB and pulled Spirorhynchus out of its cosy stinky home myself (well, watched the A-frame operator do it). Best bday (shared with the captain) EVR!!

The only paper I found showing micrograph of Spirorhynchus was Joan Bernhard's Nature paper 'Santa Barbara Basin is a symbiosis oasis' from 2000. A couple years after seeing it, to my amazement, Joan went to SBB again and brought a sample. It was still there!! www.nature.com/articles/47476

Well, yes way! It looks just like the drawing, over 110 years old. When I first saw a live cell in a saltmarsh sample in Cape Cod, over 10 years ago, I couldn't contain my happiness. It exists! Then, we found it again in several sites in Rhode Island with @symbiosisrox.bsky.social!

When I first saw the drawing of Spirorhynchus in da Cunha, 1915, isolated from Brazilian Manguinhos, I thought nothing can really look like that - ectosymbionts organized in tuft balls spiralling around the cells? No way! #ProtistsOnSky #MicroSky

New paper out! 💌🔬Spirorhynchus verrucosus is a Muranotrichean and its sister has been livin' in the deep sea Santa Barbara Basin since the 90's! See them TUFTS!! Wonderful work of B Bourland & Cepicka Lab, R Beinart, & J Bernhard enabling deep sea sampling. Read h1.nu/spiror #ProtistsOnSky #MicroSky

So.. I really hope NCBI GenBank is not working just.. very temporarily and for unrelated reasons.

Fun sampling mangrove sediments with my students today! Logistics difficulty: 0/10 - we literally just walked down the lab, as Isla Magueyes is surrounded by mangroves all around. Love the island!
