Known as ngu thang maphao daeng in Thai.
They can be voracious feeders & sometimes bites result from feeding response.
Sometimes kept as pets w/ temperament ranging from docile to defensive.
If threatened, 1st reaction is to crawl away & hide. If that doesn’t work, they’ll raise front half of body off ground & go in classical S position while twitching tail against ground/surrounding objects creating distracting noise. If that doesn’t work & provoked enough, they’ll bite.
