Create an ecosystem: reply to a comment to develop a food / ecosystem web, or create a new web with an original creature

Parent creates an original creature or organism, children (and grandchildren and great grandchildren) create another creature that directly interacts with the animal (or plant) they replied to on the food / ecosystem web. be as creative and out-there as you want!!

Very basic ex:

• Parent: a cat-sized insectivore with a ringed tail, has quills along its back
• Child: large beetle, prey of ring-tailed quill-cat, that eats bark and has bioluminescent wings. is also known to teleport at times, usually during a new moon
• Gchild: A bird with a lizard-like scaly face and underbelly that uses the beetle's bioluminescent wings to decorate their nest and attract a mate. Its song sounds eerily like a scream (but no humans exist to recognize it)
• GGchild: A large color-changing opportunistic carnivore, steals eggs in desperate times, regurgitates undigestible material, such as egg shells and bones

1 rule:
Please no creatures where the ecological niche is hyper intelligence and industrialization. Moderately advanced intelligence is fine, even small natural societies, but please nothing with "take over the world" abilities. nothing kills the fun like imagining an interesting creature with a role in an ecosystem, and being responded to with something like "bipedal hunter, uses advanced tools to launch small metal projectiles at prey, has hunted above creature nearly to extinction."
if you post stuff like this, you will be asked to edit your response to something more game-friendly

HOWEVER, descriptions of creatures made by humans IS allowed, like if humans are an alien species observing the ecosystem from afar. The only thing not allowed is trying to creature a creature that basically dominates the ecosystem

I'll post a few to start!
