Can bushmaster snake survive in captivity?

Theoretically yes - provided the keeper can provide a habitat to mimic its natural environment. HOWEVER - they are a highly-venomous species - and should NEVER be kept by a novice ! Most venomous snakes bite once then leave the victim to succumb to the toxins. Bushmasters deliver multiple bites - all injecting venom ! Even the bite of a juvenile specimen can be fatal to humans.
