forewarning I’ve Never used this site so apologies if I mess something up!

Egg Description:

   It’s found in a dark and damp spots, usually covered in cobwebs and spiders 

Hatch Description:

   This small creature is very nervous, preferring to stick to high altitudes when possible. Due to its small size it’s body isn’t large enough for its front legs to fully touch the ground.

Hatchling Description:

   More mature and more confident, this creature likes to pick fights with other dragons its size. Able to fully walk on its six legs, with some difficulty at times. Is seen often chewing on its forelimbs and scratching at its antenna due to the spikes fully growing in

Adult Description:

   This stealth hunters have returned back to the shadowy and dark areas from whence they came. This large dragons prefer to trap and then stab their prey when it’s immobilized. A common rumor is that the females eat the males, no one’s sure if it’s true or not.

and now the gender differences :D! Females have much larger striping whilst males are much skinnier, and females antenna/horns are larger and visually act more like ears whilst males stay smaller and stuck to their head.

also the spider-man idea is a joke so pls don’t take it seriously!

the spinnerets idea could be potentially for an alternative form but that’s just a concept :)!
