Why tarantula molting can take longer than usual? Bigger tarantulas especially, require more energy and time to shed their exo-skeletons while younger specimens like slings and juveniles usually only take about an hour or two. The Goliath Birdeating Tarantula or Theraphosa blondi in the video is from a friend @alongweightogo [Louvaine Hunt] and the beautiful specimen in the video took about a full day to molt and put on massive size! #spider #tarantula #pets #animals #goliathbirdeater | Ace Meta
