Reproduction and Lifespan
Manatees have a slow reproductive rate, which is a significant factor in their vulnerability. Females typically give birth to a single calf every 2-5 years after a gestation period of about 12 months. Calves are dependent on their mothers for up to two years, during which time they learn essential survival skills such as foraging and navigation.

In the wild, manatees can live up to 60 years, although many do not reach this age due to various threats.
Conservation Status and Threats
Manatees are classified as vulnerable to extinction, primarily due to human activities. The primary threats to manatees include:
- Habitat Loss: Coastal development and water pollution have significantly reduced the natural habitats of manatees.
- Boat Collisions: Manatees often inhabit areas with heavy boat traffic, leading to frequent and often fatal collisions.
- Entanglement: Fishing gear and debris pose a significant threat, leading to injury or death.
- Climate Change: Changes in water temperatures and sea levels affect the availability of suitable habitats and food sources.
