That dragon charges at you shortly after being spotted. If you have low light, the collected light children might scatter when it charges, forcing you to recollect them. As a countermeasure, you could hide behind cover or try to move without being spotted in the first place~ Basically, only the crabs and the dragon attack. There are also stones that damage you if you touch them (the red glowing ones), but they're only in specific areas, so don't worry 😉 So, the dangerous places are basically just the areas called the 'Wasteland' and the 'Storm Zone'.

I used to play this a long time ago. I heard there's a trick to dodging dragons, but I was terrible at it. I think I watched gameplay videos for tips. Also, there are crab-like or hermit crab-like enemies that deal damage, but I think you could flip them over with a sound? when you're on the same ground.

The dragon-like one: Are you referring to the Dark Dragon (commonly called 'Shrimp')? I believe it was emitting a searchlight-like beam. Once it spots a player, the searchlight turns red with a 'Jakin!' sound effect, and it charges at you in about 5 seconds. Here's how to deal with it: ① Hide behind cover when spotted When you hear the Dark Dragon's 'Jakin!', hide behind an object that blocks its line of sight. It will return to an undiscovered state when the light turns blue. ② Dodge just as it charges (※Advanced players) You can find videos by searching "Shrimp dodge" on YouTube. ③ Avoid being spotted in the first place Try flying over the Dark Dragon to prevent it from even making the 'Jakin!' sound. As for other attacking creatures, perhaps the Dark Crab (the insect-like creature you first encounter in the Forest or Wasteland)?
