In this image, a compilation of three independent Sminthurides cf bifidus/penicillifer found in the same sample, male, female, female. I picked the largest specimens from the sample.
(left to right, image I, II and III)
In image I, 2 branches are visible and the tip of the unguiculus (uu).
In image II, 3 branches are visible and the the tip of the uu.
In image III, 2 branches of the filament are visible and the tip of the uu is hidden - probably due to the angle of the specimen.
Literature research;
I learned that the apical filament is branched, but this filament is not a direct extension of the tip of the uu. Thus, NaOH is not useful to deter an assumed separation of the filament and the empodium.
Tough one, but I found some text about these species. Fjellberg lists penicillifer as having many branches. In his drawing (103C; page 180), the filament on claw 3 is drawn with many branches, but the tip of the uu is also drawn and deviates. see also drawing (104F, page 180).
Ferreira et al. (2021) describes Sminthurides bifidus as having 2-3 branches in the apical filament. Here also, the drawings distinct the tip of the uu from the apical filaments.

In the obvious next step from the straight lines of Pick-a-Stick, curves are plotted between the successive points in the strange attractor. The artist is of the opinion that the results are among the most beautiful available on pixelbrain so far, and has so far amassed several engrossed hours watching them emerge out of the darkness. (These, more than any so far, are worth launching the applets for...)
Created using Processing.
See pixelbrain for more, and try out the applets to watch the images being formed.

looks like straight out of a horror movie :)
should give some meaningful skeleton of the lung structure, so it might need some work...

This shock wave plows through space at over 500,000 kilometers per hour. Moving upwards in the beautifully detailed color composite, the thin, braided filaments are actually long ripples in a sheet of glowing gas seen almost edge on. Cataloged as NGC 2736, its narrow appearance suggests its popular name, the Pencil Nebula. About 5 light-years long and a mere 800 light-years away, the Pencil Nebula is only a small part of the Vela supernova remnant. The Vela remnant itself is around 100 light-years in diameter, the expanding debris cloud of a star that was seen to explode about 11,000 years ago. Initially, the shock wave was moving at millions of kilometers per hour but has slowed considerably, sweeping up surrounding interstellar gas.

Hyllus is a genus of the spider family Salticidae (jumping spiders). The jumping spider family contains more than 500 described genera and about 5,000 described species, making it the largest family of spiders with about 13% of all species. Jumping spiders have some of the best vision among invertebrates and use it in courtship, hunting and navigation.
Jumping spiders are generally diurnal, active hunters. Their well-developed internal hydraulic system extends their limbs by altering the pressure of body fluid (hemolymph) within them. This enables the spiders to jump without having large muscular legs like a grasshopper. Most jumping spiders can jump several times the length of their body. When a jumping spider is moving from place to place, and especially just before it jumps, it tethers a filament of silk (or dragline) to whatever it is standing on.
