- At breeding period, the female produces pheromones, a smell that attracts several males and form breeding balls of 1 female and several males.
- They give birth to fully developed live young, who are immediately able to live on their own.
- These constrictors are ambush hunters. They lie in the water or in the vegetation, waiting to pounce on passing prey.
- They have a very slow digestive system and can go for months without eating after a big meal.
- Along with their incredible jaw flexibility, they have more than a 100 curved teeth that help to hold and swallow prey.
- Like most snakes, they rely heavily on their fork-like tongues and chemo-sensation to navigate their environment and find prey. The tongue is flicked in and out of the mouth to taste the air.
