Venomous species guides, care sheets & breeding tips
6 guides written for permitted keepers and apprentices: the husbandry numbers, the handling protocol that keeps the numbers irrelevant, and what breeding each species actually commits you to. Nothing here replaces a permit, a supervising keeper or a confirmed antivenom plan.
Read this first
Venomous keeping is permit-controlled in most places, and city rules are often stricter than state ones. Confirm your permits, liability insurance and which hospital stocks the right antivenom before you acquire an animal — and keep those documents together in the venomous portal. This content is husbandry information, not medical or legal advice.
Intermediate venomous
Western hognose snake
Heterodon nasicus
A rear-fanged colubrid with a mild, saliva-borne toxin. Bites are rare and usually cause nothing worse than local swelling, but it is the honest entry point into rear-fanged keeping: same record-keeping discipline, far lower consequence.
Mixed · 18–30 in (46–76 cm), females larger
False water cobra
Hydrodynastes gigas
A large, intelligent, semi-aquatic rear-fanged snake that hoods when threatened. Bites are painful and swell dramatically, and the size means a feeding-response accident actually delivers venom — this is a serious step up from a hognose.
Mixed · 6–8 ft (1.8–2.4 m)
Advanced venomous
Expert only
Western diamondback rattlesnake
Crotalus atrox
A large, defensive, high-yield pit viper. Hardy in captivity and easy to feed, but the venom yield and strike range make it a two-keeper, shift-box-only animal from the day it arrives.
Hemotoxic · 3–5 ft (0.9–1.5 m), occasionally 6 ft
Gaboon viper
Bitis gabonica
The largest venom yield and the longest fangs of any snake. Deceptively placid, which is precisely the danger — keepers get comfortable, and a cytotoxic bite from this species is limb-threatening even with antivenom.
Cytotoxic · 4–5 ft (1.2–1.5 m), extremely heavy-bodied
Monocled cobra
Naja kaouthia
Alert, fast, and capable of striking upward from a hood at close to a third of its body length. Neurotoxic venom can progress to respiratory failure within hours, so airway support and antivenom access are the whole plan.
Neurotoxic · 4–6 ft (1.2–1.8 m)
Track the compliance, not just the care
Permits, insurance renewals, vet visits and apprenticeship hours all live in the venomous portal. Non-venomous husbandry specs are in the species care guides, and state-by-state legality is on the reptile laws page.
