a few days ago, I have found gunshot fish (it would be funny if gunshot fish was its common name since it doesn’t have one yet)

(it says I visit often)

this fish 1.2 cm in length can make 140 dB sounds (by striking its own swim bladder with its rib, if I understood correctly)

but due to how sound works and also how water affects sound it would be less louder from a distance

but still loud

they say specialized ribs and muscles allow the fish to not instantly die when it makes the sound, but I haven’t found much detailed explanation on how exactly they help the fish not shock itself to death with the sound

pistol shrimps have these funny organs called orbital hoods that serve as helmets to protect themselves from their own shockwaves made when they snap their claws, preventing brain damage. but I don’t see any possible organs in this fish that could shield itself from its own noise.

maybe it’s unnecessary because the pistol shrimp’s noise is much louder than D. cerebrum’s, at 210 dB but I still think 140 dB is still dangerous enough for a fish smaller than a penny (also this fish is smaller than most pistol shrimps)

yeah

This may be a dumb question but

Do we know how flexible sauropod necks were? I’ve seen them often depicted as kinda stiff, like a giraffe’s.

But birds with longer necks, like waterfowl, are *incredibly* flexible.

So we’re sauropods similar? Or do we think their size would restrict flexibility in favor of stability?

Thanks!

Flexibility in the neck is all about the number of neck vertebrae

Giraffes, like all mammals, only have 7 neck vertebrae, making their necks very inflexible

Swans, an example of a long necked waterbird, have up to 25 neck vertebrae

Different sauropods have different numbers of neck vertebrae, but some have as many as 19

So not quite as flexible as waterfowl, but certainly more flexible than giraffes!

The rotating shoulders and extending elbows that allow humans to reach for a high shelf or toss a ball with friends may have first evolved as a natural braking system for our primate ancestors who simply needed to get out of trees without dying. Dartmouth researchers report that apes and early humans likely evolved free-moving shoulders and flexible elbows to slow their descent from trees as gravity pulled on their heavier bodies. The paper, "Downclimbing and the evolution of ape forelimb morphologies," is published in Royal Society Open Science. When early humans left forests for the grassy savanna, the researchers say, their versatile appendages were essential for gathering food and deploying tools for hunting and defense.

Epithelial cells – those lining cavities such as the gut as well as covering organs – packing into tissue take on a 3D shape dubbed scutoid enabling tissue curvature. Here, by studying sea star embryos, the combined influence of cell density, tissue compaction and cell proliferation on scutoid formation and resulting epithelial architecture is revealed

In the modern age of the Voltuade, Dominus are considered to be a species of legend in most territories outside of the Ridge's edge. Cultural icons used by the leadership of Cacean tribeships, lone gone relics or engineered constructs of the old civilization. Whispered tales tell of different types, variants of the wars of corruption. Of betrayals of allies and ruler, though most Tenebraen Collective historians tend to dismiss these as local legend rather than fact. Within the core of the ridge though. Past pirate and salvage expedition shunt routes, upon artificial worlds and super structures of the old civilization, they are hardly consigned to legend.
