The Cavern (Seed world Evolution Game)

For this, A few notes:

I like the fang development, just so you know they currently don’t have any teeth at all so it would be a new adaptation (you seemed to be typing thinking they already had teeth, if not just ignore this)

Caecilians breathe through their skin, so there isn’t really any need for them to evolve lungs and then long breath holding when they could simply already breathe underwater

And third, why do they go out and hunt brontos? I thought you said they couldn’t eat them anyway

But still, I love the creature itself, and the Hatchetfish evolution Frale. The fish would look sick at night because of their glowing spots. What would they eat btw?

As for the Caecilian descendants becoming stunned or blind on the surface, this wouldn’t be a problem right? Normal Caecilians are blind and live there, and for these seeing such a range in the dark what if they simply came out during the twilight/night, thereby avoiding the light, and slithering back into the water at day

Striked out but is irrelevant

I thought they were venomous?

Hmm, didn’t specify fangs. They don’t hunt brontos, they just lash out at litterally anything that moves within 10 feet (3 meters) they prolly thing the bronto leg is the target tbh. Also they are evolutionarily incentivised to keep doing to so brontos stay scared and don’t just stomp them.

Just going to put this here for the potential ecosystems to get going:

Ancestor: Diatoms
Name: Cave Diatom
Description: Able to photosynthesize using the light made by Cave lights, these tiny plants thrive in the caves, their tiny metal cell walls discouraging most animals from eating them, though some, like cave copepods, still feast away regardless of this

Ancestor: Atlas bear
Name: Edge bear
Description: It is slightly larger than its ancestors, more adapted to the cold conditions of the mountains, it becomes the super predator of the mountain ecosystem, feeding on Frost Titan whenever possible. It has fur and a thicker layer of fat to cope with the cold.

i didnt see any predeur of the edge vally

Ancestor: Ermine
Name: burrower ermine
Adaptations: a muscle at the base of the external ears that allow them to be folded.
Size: the same
Habitat: the surface near the valley edge, burrows

Ancestor: Brachiosaurus
Name: bonefeet branchio
Adaptations: bone plates on their feet to protect them from slimewrathe
Size: tinier than a brachiosaurus
Habitat: surface

Ancestor: Crested Groshawk
Name: giant groshawk
Adaptations: a bigger body and wingspan
Size: significantly bigger than ancestor
Habitat: surface (everywhere where there are other animals)

Ancestor: Guam Rail
Name: edge rail
Adaptations: enzymes that allow it to eat frost ivy and a shorter neck
Size: the same
Habitat: edge of the valley, this species is the basis for many carnivore diets in there

ancestor:slimewrathe
name: nightmaer
Description: i need to clarify two things, first, how utterly devastating bonefeets are for the slimewrathes, their whole strategy is based in intimidation. they are glass cannons, they oneshot themselves when someone sneaks up on them, their skulls can be pulpified by a human with a rock, they have important arteries everywhere, in general weak af. now if you can oneshot a bronto, that doesnt much matter. everyone leaves you alone and suddenly your greatest concern is managing not to scare away prey. scond, the nightmaer is a mess. like quezels or humans or giant snakes, they are temporary anomalies. weird quirks of the environment. as soon as giant dino corpses arent available, or farming becomes unfeasible, or semi-competent mammals get develops, these guys went away. so yeah, next up the actual dudes: huge. 40 feet long, stand up to oneshot brontos on the mother :belgium: ing neck, swallow half the body, drag it underwater with everything outside of the nightmaer’s mouth being eaten away, as they still cannot chew, and rely on other spicies to chew away most of their prey. they are super endangered, with the whole valley supporting only a few, and they inevitably go extinct, though a 20 foot long dwarf sub-species makes in it the deep ocean.

lol mega sneck go brr. mega sneck ded i sad now:(

They are generalists omnivores

Ancestor: Candy Striped Hermit Crab
Name: hardback hermit crab
Adaptations: because of the low amount of shells they evolved an harder abdomen to protect themselves
Size: bigger than ancestor
Habitat: surface ocean

Ancestor: Brachiosaurus
Name: Mountain Leaper
Description: Significantly smaller than their ancestors, these agile dinosaurs hop from rock to rock on the sides of the valley, before the valley edge, eating the scraggly plant life that is present. It has sacrificed size for speed and agility, rapidly able to escape any potential predators

too much of a change and behavior (imo)
how did giant dinosaurs transform into basically mountain goats.

They were already forced into the rocky valley edge by the slimewraiths, as well as the temporary reign of the Nightmares, so while one branch simply migrated and another evolved bony foot-plates, a third group of smaller brachiosaurus simply stayed in the rocky areas full time, to avoid said ‘predators’, and needed to be nimble to be able to optimize their ability to live their, which came at the price of size

Plot armor?



No? Not really, that was just my reasoning for making them able to live in the rocky areas.

Ancestor: Warrah
Name: jumper wolf
Adaptations: longer legs, a shorter mouth
Size: slightly larger than a warrah
Habitat: valley edge
Diet: carnivore
Description: a predator that evolved to hunt mountain leapers.

Ancestor: Hawksbill Sea Turtle
Name: Zaratan
Description: A giant descendant of the Hawksbill sea turtle, these creatures can almost be mistaken for small islands when they break the surface of the waves to breathe, diatoms clinging to their shells. They are giant omnivores, opening their mouths in the seagrass meadows and eating anything they happen to swim by that can fit in their mouths, though they are generally gentle giants, similar to whales in terms of intelligence

By small islands I mean like really small islands, no more than 10-30 feet across (I’m not good with measuring distances if that’s insane still let me know)

Ancestor: Waving Starts
Name: Heat Wavestars
Description: In order to escape competition, their group began to settle in Hydrothermal Vents and began filtering out heat-loving bacteria and chemotropics. To cope with the heat, some of their bodies began to be covered with a layer of bacteria as protection. Their ability to communicate on the radio has been perfected and they are now able to signal it of danger.

Ancestor: Nursery Shark
Name: Hydrosharks
Description: They started looking for food in the depths and eating for Heat Wavestars who started living near the Hydrothermal Vents. They are much larger because of the pressure and also for surviving in the depths. They swim much slower and eat anything but the occasional Heat Wavestars.

Interesting fact, radio doesn’t work underwater. Sorry to disappoint.

it can work, in low fercan

" VLF radio waves (3–30 kHz) can penetrate seawater to a few tens of meters and a submarine at shallow depth can use them to communicate." From wikipedia

ahhh sorry ive heard that communication underwater is impossible because of range limitations, but thats for things like navys where range needs to be miles, not weird sea blobs, where the few tens of meters is plenty
