The Tanaconda is a hybrid animal created as part of the Chaos Effect line. It is a hybrid of the prehistoric reptile Tanystropheus and the modern Anaconda.
A silent hunter, the Tanaconda is a perfect amphibious predator. Its long neck is ideal for darting after fish and constricting any unlucky land-based prey. Venom glands located in the Tanaconda’s throat inject poison into its victims through lethal, piercing fangs.
- The name Tanystropheus means "long vertebra", and the name "Anaconda" may derive from the Sinhalese words hena ("lightning"/"large") and kanda ("stem"/"trunk"). Thus, the name "Tanaconda" could mean "long trunk" or "long stem".
- The Tanaconda is venomous, even though neither Tanystropheus nor anacondas are venomous in real life.
