Whatever Catches My Fancy

Variations

Nimloth lives and ends magnetically pulled into Túor’s polycule, because he does that to people. The histories only say that she married Voronwë, one of the few elves to remarry, and speculate that her husband’s mortal nature made such a feat imaginable. But keen eyed historians note that she and her second husband drop out of the books at the exact same time that Idril and Túor make their last voyage. (Eärendil and Elwing lose all their remaining parents at the same time.)

Nimloth lives and raised her daughter to bear the Silmaril proudly. When the Sons of Fëanor come with their demands she cannot bear to see her home burned again. She’s lost two children to them. She sneaks out at night and goes to them under cover of parley and manages to kill Maedhros before being killed herself. This changes nothing about the future except making Maglor a more unhinged kidnap-guardian.

Nimloth lives and cannot bear to see her daughter killed by those who have already stolen two children and a husband away from her so she bears the Silmaril out and gives it to the Sons of Fëanor. Everything changes, the Valar are not petitioned, Morgoth goes unchallenged, Beleriand burns, everyone dies horribly.

Nimloth lives and fights in the Third Kinslaying to protect her young grandsons. She intends to die, instead she finds herself waking up beneath a healer’s hands when Gil-Galad’s reinforcements come. Elrond and Elros are gone and she fights every day to get them back, through diplomatic and extradiplomatic means. The Fëanorians refuse to send even proof of the boys’ safety, until one day when they’re put on a boat and sent to Balar. They barely remember her but they make new memories. She dwells in Númenor with Elros’ kin for years, and after that finds a home in Mirkwood and visits Elrond often.

Nimloth lives only to die in the Third Kinslaying avenging her sons by killing 2 whole sons of Fëanor. If Dior can get 3 then she can have 2. Sans Maedhros and Maglor, Elrond and Elros have a less deliciously upsetting childhood with Gil-Galad and the Valar end up with two extra Silmarils on their hands after the war. Nimloth spends the next three ages getting high-fives in Mandos.

The term "semi-slug" is used to describe an intermediate stage of evolution that occurs as snails evolve into slugs. Nearly 1,000 different species of semi-slug are currently known to exist, and these bizarre little creatures can be found on at least four continents.

Above: Fastosarion brazieri and Varadia amboliensis

Each species of semi-slug is technically still classified as a snail, but its shell is noticeably reduced, becoming smaller and more internalized as the species evolves. A semi-slug officially becomes a regular-slug once its shell is no longer visible at all.

As this article explains:

If life were simple, there would be snails and slugs. Snails carry their homes on their backs; slugs are naked and embarrassed. But life isn’t simple, so of course there’s secret option #3 – the semi-slug, a bizarre creature that sits exactly between the snail and the slug.

Above: genus Satiella and genus Euaustenia

This article describes the distinction between a snail, a slug, and a semi-slug:

In contrast to snails, which have an external shell large enough to accommodate the body, or slugs, in which the shell is completely internal or absent, semi-slugs have an external shell, but the shell is too small to accommodate the animal’s entire body.

Above: Megaustenia siamensis

The evolutionary process that causes the shell to recede is known as limacization, and it's especially common in moist, low-calcium environments where a snail's shell may be more of a burden than a benefit:

Terrestrial slugs are not a monophyletic group, but a case of convergent evolution in which the slug form evolved from different lineages of land snails that gradually lost their shell through a process called limacization. Limacization resulted in adaptive radiation in land snail lineages, as slugs became adapted to diverse moist and protected spaces, such as crevices in rocks and wood debris. The loss of the shell also allowed for more movement and less calcium dependence, making slugs more successful as pests.

Above: Gaeotis nigrolineata, also known as the Puerto Rican semi-slug, has a neon green shell that is almost completely internalized, but the shell is clearly visible through the semi-slug's translucent body

Some semi-slugs have shells that are still opaque and largely visible, with a patch of flesh covering only the outer edges of the shell, while others have shells that are more significantly reduced, transparent, and/or concealed.

This topic was mentioned in my previous post about Ibycus rachelae, but I wanted to write a more detailed post about semi-slugs, because they're just so fascinating and weird.
