- Boas reach sexual maturity at 2-3 years of age.
- The female attracts a male with a special scent she emits.
- Fertilization is internal.
- Boas are ovoviviparous, meaning they produce eggs that hatch within the body so that the young are born live.
- 20-60 young are produced in one litter.
- The boa has wonderful camouflage to resemble leaf litter.
- They are also great swimmers; however, they prefer to remain on land.
- To hunt, snakes stick out their forked tongue to collect scents.
- Once collected, the snake will insert the tips of the forked tongue into its Jacobsonâ€™s organ, where the data can be analyzed.
- The Jacobsonâ€™s organ interprets the chemicals such as pheromones to aid the snake with finding its next meal, or even a mate.
- The boa is an ambush hunter and lies in wait of its prey to come to it.
- The boa uses its teeth to catch prey, but as it is a constrictor, it squeezes and suffocates its prey before swallowing it whole, usually head first.
- The boa constrictor can hiss loud enough to be heard 100 feet away.
- The number of boas is dropping because of habitat destruction and the skin trade.
