Interested in seaweeds, microalgae, protists, bacteria and those interactions. Love culturing and the observations. Focusing on algae in islands too.

Filamentous green alga. Who will know what is this organisms? #Timelapse image for c. 28 hours, shown as 11-seconds, 30 frames movie.

Old shrine.
An excellent sampling site for airborne (aerial) algae.

[shimanumu @IslandsAlgae]

Green Noctiluca (not really greenish in this photo...) and Pedinomonas symbiotic within its vacuole.

[shimanumu @IslandsAlgae]

Cyanobacterial bloom, mainly Microcystis colonies of various sizes and shapes. Beautiful coloration! Stereomicroscopic image.

Recent best shot. A tardigrade on a diatom.

@CcacOf interesting.. swimming cell of Platychrysis?

[shimanumu @IslandsAlgae]

@CcacOf Tetraselmis/Prasinocladus, marine - brackish

[shimanumu @IslandsAlgae]

@CcacOf Probably cyanelle, but I am not sure which organism originate

[shimanumu @IslandsAlgae]

I realised I haven't tweeted about seaweeds for a while.
Aeration culture of sporophyte of Cladosiphon okamuranus. This is the starting point of my seaweed research and the latest photo.

Happy #phycologyFriday! Finally, I got nice images of neutral #zoospore from the plurilocular #zoosporangium of Cladosiphon.

Skeleton of radiolarian and Triceratium from deep sea sediment.

[shimanumu @IslandsAlgae]

Living foraminifera with symbiont and fixed one stained with Rose Bengal.

[shimanumu @IslandsAlgae]

Movie of one radiolarian, probably Dictyocoryne. We can see the large, thick axoflagellum. The symbiont seems to be haptophyte according to the figures of the following reference.

Something interesting radiolarians observed during the last voyage. All possess symbionts!

Just returned safely from a month-long research voyage. Ocean research is still great and there is always something new to discover! I got very interesting organisms, very fortunately.

[shimanumu @IslandsAlgae]

@savitoxin @FlowCam great system!

[shimanumu @IslandsAlgae]

@JanousekWild @algabase @OlympicNP Excellent photos!

[shimanumu @IslandsAlgae]

@GrCarlos_tech Thanks
I used stereomicroscope, ZEISS Stemi 305. Photo was taken by dark field mode.

[shimanumu @IslandsAlgae]

Botryococcus was dominated in one of the reservoir samples.

[shimanumu @IslandsAlgae]

True-branching cyanobacteria, probably Fischerella.

I am not sure, but probably Cladophora opaca. I miss coast and field survey... Too busy at the desk
