More bug questions (but also bacteria) what's up with bioluminescence??? Like I know with lightning bugs it's a mating thing, but what about glow worms, or those bacteria in the ocean that make it light up nuclear blue sometimes??? Like what's up with that???????

Lots of reasons! (Yes, Wiki links, I know--check the sources!)

Sometimes, for the same reason predatory fungus gnat larvae (and bug zappers) luminesce--to attract prey! Like flying insects, deep sea organisms orient themselves by the light filtering down from above. Many pelagic organisms make a nightly journey to the surface. So, like insects, they'll go toward the light.

Because it looks like the lights from the surface, it can also be used as camouflage.

They might also bioluminesce to make themselves a flashlight. Red light cannot penetrate deep below the water's surface, so many ocean animals are blind to it. An animal that casts its own red light, and is the only animal around that can see that red light, can see in what would be darkness to everyone else. Such is the method of the loosejaw.

Other animals, like vampire squids and bomber worms, emit a dazzling display of blinding bioluminescence to disorient predators.

That said, some deep sea animals *do* bioluminesce for mating displays! Some ostracods, for instance.

Symbiotic bacteria luminesce because their host relies on it, and they rely on their host staying alive. As for why non-symbiotic bacteria luminesce...well, it depends on the bacteria, and apparently we're still not sure. One hypothesis is that it helps mitigate oxidative stress.

Or maybe it's just to make the ocean look cooler.

In the act of working on Ponzu’s reference and solidifying that she’s an ambassador from a deep-water zora realm, I got to thinking about what the other residents might look like. Very rough concepts here.

Ponzu is based on a species of chimaera that travels to shallower waters at night/to spawn, so by extension she’s more suited to go ashore to the main zora domain for diplomatic reasons. The other deep-water zora, however... generally most of them are not so suited to it. Both as far as what they can put up with physically, and how their appearance is taken by the mainlanders. They can be standoffish towards anyone not of their realm, don’t speak much to the point they can be mistaken for mute entirely, and the inability for some of them to emote with facial expressions makes them come off as unnerving.

Daily fish fact #447

Stoplight loosejaw!

They’re able to produce red bioluminescence, the only fishes to be able to do so! Because red is the first colour that gets absorbed into water, deep sea fish tend to not be able to see red light. The red l bioluminescence therefore gives the stoplight loosejaws a light to hunt with that only they can see!

Day 11: Deep Sea fish

The Stoplight Loosejaw

They both can see and produce red light, which gives them an advantage in the twilight and midnight zones. The bioluminescent organs around their eyes earned them the name "stoplight"

my secret santa gift for @evilfarmin!!! ^__^ featuring stoplight loosejaw mermaid etho bc that's my fav fishy <3

ID: digital fanart of EthosLab as a mermaid against a white background. He has dark green, dark blue, dark purple, and black scales that cover his neck, torso, tail, and the top of his forearms. His mask is made of seaweed and he has red bioluminescent photophores under his eyes.

On the upper left, he is drawn from the shoulders up with a casual expression while looking off to the side.

On the upper middle, he is drawn from the shoulders up with an angry expression while looking at the viewer. His photophores are glowing bright red, and he is against a dark ocean background. Above him is a photo of a stoplight loosejaw in real life.

On the upper right, he is drawn from the neck up at a side view with his eyes closed. He has his mask off, showing his jaw that resembles a stoplight loosejaw's. It has an extra hinge hidden underneath and sharp teeth.

On the middle left, his eyes are drawn looking at the viewer with a casual expression. His right eye is blue, his left eye is red, and there are two red photophores underneath both of his eyes. He also has a pale scar over his left eye.

On the bottom, he is drawn swimming with his right hand resting behind his head and his left hand pointing up a finger gun with sparkles drawn around it. He has a carefree expression, and his scale color slowly shifts from dark green at his neck to dark blue at his hips to dark purple at the base of his fins to black at the tips of his fins. End ID

(feel free to correct me if any of the below information is false! I'm just one guy! I won't be able to edit these posts, but a correction is always appreciated anyways)

Stoplight Loosejaw is a species of dragonfish with bioluminescent "stoplights" beneath their eyes! They can unhinge their jaw and shoot it forward to eat prey!

Oarfish are mysterious huge fish that we mainly know from the remains that wash up on shore! It's theorized they could be the origin of "sea serpents" in old stories! They get to be about 26 ft (8 meters) long!

Let’s talk about the Stoplight Loosejaw. This little black animal is a type of deep-sea fish.

[Image from "Oceanic Ichthyology" by G. Brown Goode and Tarleton H. Bean, 1896]

Now this is a very weird and interesting creature: its bones are so soft that you could easily insert a needle into its skeleton (why you personally would want to, I don’t know, but it’s a thing that scientists did, apparently), and its lower jaw, which makes up a quarter of its length, doesn’t have a floor, just one big hole where flesh should be therefore reducing water resistance and allowing the jaws to be snapped shut more quickly (which allows it to catch prey more easily).

Pretty neat already.

But what is most interesting about this animal is that it is one of the few fishes that can produce red light (bioluminescence!!!) (it can also produce green and blue light, but though interesting, red is cooler in this instance).

The red light is especially valuable when hunting prey because red light doesn’t penetrate very deeply in the ocean waters, unlike blue light, so most animals that live in deep waters have evolved camouflage that takes into account blue light and not red light.

For example, that’s why there are a lot of red crabs: in deep waters, that red colour doesn’t actually look red because there is no red light at that depth; instead, the crab will look black and will therefore be very hard to spot.

And because there is no red light deep in the ocean, very few animals have evolved to see that type of wavelength, meaning that the loosejaw can see the red little fishy swimming about, minding its one business, but the red little fishy cannot see the glaring red light shining on it and therefore does not know it’s about to meet its end.

Really, an incredible feat of adaptation, not so much for the red little fishy minding its own business, but definitely for the stoplight loosejaw.

(like a lot of deep-sea creatures, it’s not exactly a looker, but who am I to judge)
