I am fully aware that siphonophore are not bacteria, you do not have to keep telling me

I’d like to throw my own theory out here and say that the reason hazers may be found on land rather than in water is because they mainly swim around when everything is flooded by the rain, and end up beached on land when it all dries up.

I suspect Green Lizards might be specialized to hunt other lizards, with their reduced agilit in favour of a stronger bite and greater endurance

You forgot to tell about the eggs that noodle flies put in the ceilings. If you actually get one of these eggs, put them on a shelter and wait 1 or 2 cycles, it will, hatch, containing 2 or more baby noodle flies who will follow thinking you're their mother. I do not know a way of noodle flies making these eggs, but i do know that if you have an egg in your hands and a noodle fly sees that, it will be angered and try to kill you the same way.

I feel like lizards are alot more engineered than perhaps we might think.

Red lizard fun fact: they will typically battle and die to green lizards. This is because while reds can deal a lot more damage, luzards usually battle with territorial bites, dealing far less or no damage. Greens play dirty, and are far less reluctant than any other breed to get lethal

I honestly think the laviathans were one of the first "solutions" the iterators came up with to solve the ancient's problem of ascending without the use of void fluid. Obviosly, it didn't work, as the slugcat is still reincarnated after being consumed by it. The devs have straight up confirmed that their similarities to the Void Worm are not coinsidences, so I think that maybe the iterators/ancients were trying to recreate the Void Worm outside of the void sea to help them ascend. My only question is how the ancients/iterators knew about the Void Worm if swimming in the void sea meant the cycle of reincarnation stopped for said swimmer. Perhaps some iterator took a dive and, since they can't ascend, were able to look at the worm without breaking the cycle of reincarnation.

Me, never having played Rain World and knowing nothing about biology: Yeah, I'm in the right place

My personal head cannon for scavengers is that they were designed as a form of entertainment by the ancients

The "poor fucker" "I need to know how these bugs fuck!!" and "Pictured here the world's most docile Miros bird" killed me you're absolutely hilarious 100% I'm a new subscriber<3

The grapple worms COULD be similar to pyrosomes OR, more likely, sea cucumbers. As both creatures are similarly tube-shaped and I believe sea cucumbers can even eject their guts out in a sticky, web-like blast to catch food.

I think jellyfish are actually descendants or offshoots from neuron flies.

Hunter 'exclusive' enemies probably aren't 'extinct' since most of them can appear in survivor (or monk?) through the lineage system.

Idea: maybe the white lizard's chromataphores are consciously controlled? If so, maybe when they flinch or feel pain, they might accidentally change their chromataphores' colours rapidly.

i wouldn't say that the red variants are necessarily extinct. you can get any advanced variant in the monk and survivor through the heritage system (I think thats what its called). perhaps the red variants simply left the area for more food and shelter. and come back when theres any open property.
