West Indian Manatee
Trichechus manatus
The West Indian Manatee is a gentle aquatic giant, often called the 'sea cow' for its peaceful grazing habits. Found in the warm coastal and inland waters of the Americas, these curious mammals are a testament to the beauty of our underwater ecosystems.
Quick Identification
Size
Typically 2.7–3.5 meters (8.9–11.5 feet) long and weighing 200–600 kg (440–1,300 lbs), though some individuals exceed 1,000 kg.
Colors
Uniformly grayish to brownish-gray, often appearing greener due to algae growth on the skin or lighter due to barnacle attachment.
Key Features
- Large, flat, paddle-shaped tail used for propulsion
- Flexible, prehensile upper lip covered in thick sensory whiskers (vibrissae)
- Small, widely spaced eyes and no external ear flaps
- Thick, wrinkled skin with sparse hair across the body

An adult West Indian Manatee and a smaller calf swim slowly through the crystal-clear water. They are accompanied by large schools of silvery fish that part as the manatees glide forward, showcasing their characteristic paddle-shaped tails as they undulate through the spring.

Several Sheepshead fish swim through the clear water, navigating around floating vegetation. In the lower right of the frame, a large West Indian Manatee surfaces near a floating barrier, briefly showing its back and snout as it takes a breath before submerging again.

Two West Indian Manatees are swimming near the water's surface in a clear spring. One individual's large, rounded tail fluke is clearly visible as it maneuvers through the water. Several small fish are darting around the manatees, and pieces of lettuce are floating on the surface for them to graze on.

A large West Indian manatee floats peacefully in the center of the frame, slowly moving its flipper and adjusting its position in the clear spring water. Another manatee is visible resting in the background. Several fish, including striped Sheepshead and plain-colored snappers, swim around and beneath the manatees.

A large West Indian manatee floats serenely near the water's surface in the clear spring. Several fish are active in the scene: multiple striped sheepshead swim around the manatee's midsection, and a common snook glides through the background on the left.

A Sheepshead swims inquisitively toward the camera lens at the start of the sequence before several large West Indian manatees glide through the spring water. The manatees move slowly through the crystal-clear water, showing their characteristic rounded bodies and paddle-shaped tails.
Behavior
West Indian Manatees are gentle, slow-moving giants that spend the majority of their time eating, resting, and traveling. Despite their size, they are incredibly graceful in the water, typically cruising at about 5 miles per hour. While they are often solitary, they are not strictly territorial and are frequently seen in small, informal groups, especially during the winter when they huddle together for warmth near natural springs or power plant discharge pipes.
These mammals are highly curious and use their sensitive facial whiskers to explore their environment and find food. They must surface to breathe air every three to five minutes when active, though they can hold their breath for up to 20 minutes when resting. While generally shy, they are known to occasionally investigate docks or slow-moving boats, though human interaction should always be kept passive to avoid disturbing their natural behaviors.

Camera Tips
Capturing the West Indian Manatee requires a specialized approach since they are almost entirely aquatic. If you have a backyard dock in a coastal or canal-front area, the best setup is a high-resolution underwater 'action' camera or a specialized aquatic trail camera mounted to a dock piling. Position the camera about 2-3 feet below the low-tide line, angled slightly upward toward the surface. This allows you to capture the manatee's face and unique 'lip-walking' feeding behavior as they graze on algae or vegetation growing on your dock.
For those using standard trail cameras above water, placement is key. Mount your camera on a sturdy post or dock railing overlooking a slow-moving section of water. Look for 'manatee boils'—circular swirls on the water's surface created by their tails—which indicate a high-traffic area. Use a polarising filter over your lens if possible to cut through the water's surface glare, allowing the camera to trigger on the dark shape of the manatee beneath the surface rather than just the ripples.
Time your captures for the early morning or late afternoon when the sun is at an angle, as midday overhead sun can create too much reflection for clear images. In winter, focus your efforts on freshwater canals or areas near warm-water outlets. Avoid using bright artificial lights at night, as this can startle the animals; instead, rely on cameras with high-quality 'no-glow' infrared sensors. Remember that manatees are a protected species, so your camera setup must be entirely passive—never submerge a camera in a way that obstructs their path or attempt to lure them with food or freshwater hoses, which is illegal in many jurisdictions.
