How Small Are Baby Manatees?
Adult manatees can grow to more than 10 feet long and weigh over 1,000 pounds. But every gentle giant starts life as a surprisingly small calf that depends completely on its mother.
If you know anything about manatees, you probably know that they can get to be pretty big. Full-grown manatees usually weigh somewhere between 800 to 1,200 pounds and reach around 10 feet in length. In fact, manatees can grow as large as 3,500 pounds and 13 feet in length!
But manatees don't start out that big as babies. Just as human babies are much smaller than fully grown adults, baby manatees are much smaller at birth. But just how small are baby manatees?
Here, we'll break down everything you need to know about baby manatees including, yes, just how big they really are.
Quick Baby Manatee Facts
- Baby manatees are called calves.
- They can swim to the surface shortly after birth.
- Most calves stay with their mothers for up to two years.
- Female manatees usually have one calf at a time.
- Manatee mothers teach calves where to find food and warm water.
Manatee Birth
When a human mother is pregnant, she usually has to carry her baby for 9 months before her baby is born. This is called gestation. A manatee gestation is actually a little bit longer, around 12 months or a full year.
Not all manatee species are exactly the same. Manatees breed all year round, which means that calves can be born at different times. However, in Florida, most manatees are born during the spring and summer months. In West Africa, most calves are born between February and May.
Manatee births are a pretty rare event. Female manatees do not start to reproduce until they are about four or five years old. When they do reproduce, manatees typically give birth only once every two to five years.
So Just How Big Is a Baby Manatee?
When a manatee is born, it weighs approximately 60 to 70 pounds and measures between about 3 and 4 feet long.
That might sound large for a baby, but compared to a fully grown adult manatee, a newborn calf is still tiny. Adult manatees can eventually become more than ten times heavier than they were at birth.
Manatees can be born either head-first or tail-first. A newborn calf will also have visible fetal folds in its skin. These wrinkles usually disappear after several weeks.
Putting It Into Perspective
A baby manatee is about the length of a large dog but can weigh as much as an adult person. Despite their size, calves still rely completely on their mothers for protection, food, and survival.
Life for Baby Manatees
Once a manatee is born, it can already float to the surface to take its first breath of air.
Baby manatees and their mothers have an incredibly strong bond from birth. Calves begin nursing only a few hours after being born by feeding from teats located beneath their mother's pectoral flippers.
Calves also begin vocalizing shortly after birth. These squeaks and chirps help mothers and babies stay connected while swimming through often murky water.
Baby manatees stay close to their mothers for around one to two years as they learn travel routes, feeding areas, warm-water refuges, and safe resting locations.
Even though many calves are weaned by the end of their first year, they may continue traveling with and learning from their mothers well beyond that point.
This learning period is extremely important. A calf that becomes separated from its mother too early faces significant challenges finding food and navigating seasonal migrations.
Why Baby Manatees Need Protection
Because manatees reproduce so slowly, every calf is important to the future of the species.
Threats such as boat strikes, habitat loss, water pollution, harmful algal blooms, and entanglement in fishing gear can put both mothers and calves at risk.
When boaters follow manatee speed zones and people help protect waterways, they directly contribute to the survival of future generations of manatees.
Manatees: Gentle Giants
We tend to think of manatees as gentle giants, but baby manatees are even rarer and gentler. Because manatee calves are so uncommon and so dependent on their mothers, we must be extra careful whenever we encounter them in the wild.
Manatees are already vulnerable creatures with relatively few defenses against predators and human activity. A calf on its own needs the protection and guidance of its mother to survive.
Hopefully, now you have an even greater appreciation for manatees and their young and understand why protecting them is so important.
