#echolocation

[sitting-on-me-bum]

A European noctule bat (Nyctalus noctula), found throughout Europe, Asia, and North Africa. It uses loud echolocation, fast flight and deep dives from above the tree canopy to catch moths, crickets and beetles.

how surprised do you think Rocky was when Ryland told him that some humans actually do have the ability to use echolocation if they practice enough?

like imagine how jealous

“Human see light like humans AND SOUND LIKE ERIDIAN QUESTION?”

[oscar-minimum-wage-stp]

A small creature resembling a cat, but with wings and a more elongated body, peeks out of Oscar's box.

*Oscar is alarmed at first, readying himself to take of if needed*

*The creature's wings look small compared to its body, Oscar can probably fly faster if needed*

(The window is open, I can escape easily if needed)

headcanons will be added here as i remember them and they come up:

full name is shachi keiko

deceased parents (a non-canon storyline that i prefer to treat as canon)

fluent in english, swedish, and spanish (his dialect is peruvian, though he has no trouble speaking to people of any dialect)

completely human, but he doesn't act like it (eats raw fish like a freak, though, he has a hardy gut and doesn't notice smaller parasitic infections from eating raw meat)

he has cannibalistic tendencies, though he has avoided harming anyone violently or by force. he tends to bite at his fingertips till they bleed, and also gnaws on his shoulders absentmindedly. he gnaws on his close friends and is often tormented by thoughts of biting them and eating them.

EXTREMELY sensitive to hot weather. will not be having fun time in the sun this year.

Fanbinding: Echolocation by Darksknight

Bind #(my numbering system is off) Echolocation by Darksknight Date Completed: 12/31/2025 Size: Octavo.  93 pages, 8,535 words Summary: Kirk and Spock don’t realize that they’ve bonded right away. The rest of the crew is a different story.

I was looking at my 2025 stats and realized the number of books I made during the year was going to end at an awkward number.  Clearly that meant I should try to cram another book in before the end, right?  It would have to be a small one because I had three days for both typesetting and binding.  And since I had a friend visiting soon I should make two copies because why not.  And I did actually pull it off!

Octavos are such a great way to use up scraps, in this case some paste paper I made over the summer and some cardstock I mis-measured for an earlier project.  It’s double sided paper and I used different sides for each copy for extra variation.

The typeset itself is very rough and ready, but a lot of fun to knock out quickly.  I didn’t even run it through spellcheck (partly because Chekov’s accent is written out and I didn’t feel like hitting ignore for every word in his dialogue).  I went a little overboard with the Astronomy dingbat font for the title page and scene dividers but stars were the logical choice.  Federation Classic for the titles and Bell MT as the body font, just because I hadn’t used it yet this year .

the thing is echolocation varies so heavily with atmospheric density because sound waves travel differently through different mediums. like sonar (another form of echolocation) is so much more effective underwater because the sound waves can travel much further and faster before dissipating.

so on Erid where there is a surface pressure of 29 atm, echolocation would probably be similarly effective to sight on the surface of Earth.

but that also means that Rocky looking into Grace's atmosphere would likely "see" things as blurrier and further away than they actually are with more distant things fading into noise. it would probably also be quite disorientating because the sound waves would travel at different speeds and relfect differently. I think an Eridian looking into a human atmosphere would be similar to a human looking into a pond or another body of water.

so when Rocky briefly goes into Grace's atmosphere, not only would he have been freezing and suffocating and burning from the oxygen, but he also would have had the eridian equivalent of tunnel vision, making his rescue of Grace even more impressive
