Dire Wolves Grow Up at Colossal Biosciences, Snacking on Deer Marks Maturation
Colossal Biosciences has brought dire wolves Romulus and Remus to life from ancient DNA, raised with surrogate dog mothers, and they are now about 16 months old with maturation to around age three. They recently fed on their first deer carcass and also catch small prey on Colossal’s 2,000+ acre preserve, illustrating their wolf nature rather than domestication. A female pup named Khaleesi, born Jan. 2025, rounds out the trio. They’re friendly toward staff when fed but remain wild wolves, not pets.
