False Water Cobra

False Water Cobra key facts

Care level

Advanced

Lifespan

10-15 years

Size

Usually about 2m, exceeding 3m at most

Diet

Frozen-thawed mice and rats, fish, amphibians

Temperature & Humidity

As an animal of marshes and rainforest it needs a humid setup with a thermal gradient.

Enclosure

This is a snake of over 2 m, so it needs a robust enclosure with a large floor area and a lid that locks securely. It is drawn to water, so provide a container big enough for the whole animal.

Diet & Feeding

In the wild it takes a broad range of prey, including fish, amphibians and small mammals; in captivity appropriately sized frozen rodents form the staple. The feeding response is very strong, so always use a hook at feeding time and keep hands away.

Temperament

Active and inquisitive, but the rear fangs and venom make it a snake for experienced keepers. Recorded bites have caused marked swelling, bruising, numbness, itching and dizziness, with symptoms more pronounced when the snake holds on for a long time.

Notes

Japan's list of designated dangerous animals covers only Dispholidus, Rhabdophis, Tachymenis and Thelotornis among the colubrids, so this species is not included. It is nonetheless mildly venomous, and both the enclosure and the handling routine should assume the risk of a bite. Species+ lists it on CITES Appendix II.

About False Water Cobra

A large South American colubrid known for its cobra-like hood display. Reaching around 2m or more, the False Water Cobra suits experienced keepers only.

7 things to know before welcoming a False Water Cobra

1. 1A Spacious Enclosure

   Adults typically grow to around 2 meters, and some individuals exceed 3 meters, so you'll need an enclosure sized for their adult length from the start. Prioritize enough floor space for the snake to stretch out and coil comfortably.

2. 2Semi-Aquatic Habits

   This species has semi-aquatic habits and appreciates a large water dish it can fully submerge in. A soaking area also helps maintain appropriate humidity levels within the enclosure.

3. 3Cobra-Like Threat Display

   When startled or threatened, this snake flattens its neck into a cobra-like hood while keeping its body horizontal rather than rearing up. In most cases this display, along with a loud hiss, is simply a bluff meant to warn off a perceived threat.

4. 4Rear Fangs and Mild Venom

   This snake is rear-fanged and mildly venomous, so a bite can cause swelling and pain. Handle it calmly and securely, and avoid bringing your face or neck close to the animal's head.

5. 5An Alert, Quick Temperament

   This is an alert, quick-moving snake, and many individuals stay somewhat defensive, so handling calls for calm, confident movements and prior experience. Avoid sudden approaches, and take time to let each snake adjust at its own pace.

6. 6Best Suited to Experienced Keepers

   Its large size, quick movements, and mild venom make this a snake best suited to keepers with solid reptile experience. If you're new to snake keeping, it's worth building experience with a more beginner-friendly species first.

7. 7Temperature and Environment

   Since this species comes from warm, humid regions of South America, maintaining an appropriate temperature gradient and humidity level in the enclosure supports its wellbeing. Provide both a basking spot and hiding places so the snake can choose the environment that suits it best.
