RADIOLARIA!

Decided to post these because I think these are high(er)-res. ,better than the usual Haeckel baloney on the net

Haeckel is pretty famous because of these depictions,they inspired people in the 19th century,and influenced art.

One accusation levelled against him is that he liked to embellish his illustrations a little too much

One has to remember: back in those days there was only light microscopy,nothing else 

BTW: all of Haeckel's illustrations(those of coral,diatoms,e.g.) have this slightly psychedelic quality

Radiolarian parts often get mistaken for poriferan(sponge)spicules:both are composed of silica,and the shapes and size can be pretty similar

(Notice how fig 1a is the spitting image of a radiolarian)

and stopping right here,because this thread was supposed to be just about Haeckels radiolarian "artistry"

The psychedelic could be down to "The Green Fairy",wormwood ( Artemisia absinthium) drink very fashionable in the 19th century with artists,writers and thinkers alikel.lol.

 

@doushantuo his drawings and investigations are fascinating.

I love Haeckel's illustrations, looking for a good facsimile (or original)...

[doushantuo 4,259]

love this one

For comparison,some by Rust:

To be fair,I think these scans could have been better,I have a feeling the originals are more photogenic than this

Like some forams,radiolaria can harbour symbionts(as documented in this article),but I'm posting this principally to show contemporary colour microscopy:

electron microscopy:

1-5 two Challengeron species(Notice that name!)

6-9: Protocystis

 

Although in slightly austere B & W,these are very beautiful,IMHO

Yvie,are you suggesting they were "absinth"-minded?
