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

A large West Indian Manatee drifts slowly through the crystal-clear spring water, its massive body nearly filling the frame. Bright sunlight filters down from the surface, creating a dappled light pattern that highlights numerous pale, linear scars across the animal's wrinkled back. In the background, several small fish dart between patches of aquatic vegetation.

Several West Indian manatees are seen swimming gracefully through the clear spring water. A smaller calf stays close to a larger adult as they drift together. Numerous small fish dart around the manatees, taking advantage of the space. The water surface reflects bright sunlight, creating dancing light patterns on the manatees' backs.
May 8, 2026
Several West Indian Manatees are resting and slowly swimming in the clear, blue water of the spring. Faint mist rises from the surface of the water, and lush aquatic vegetation is visible on the floor of the spring as the manatees glide above it.
May 7, 2026
An adult West Indian Manatee and a smaller calf swim slowly through the clear blue water of the spring. They are surrounded by a large school of small fish that move around them as they glide forward.
May 7, 2026
A large group of manatees is seen resting and drifting slowly in the clear, turquoise water of the spring. The sunlight creates shimmering light patterns across their gray, wrinkled backs as they huddle together near the surface.
Apr 30, 2026
Several manatees are seen gliding through the clear, sun-drenched waters of the spring. They are accompanied by a large, active school of small fish that weave around their large bodies. The manatees move with slow, purposeful strokes of their paddle-like tails. Later, the view shifts to the surface where several more manatees are resting, with their backs and snouts occasionally breaking the water's surface as they breathe.
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.
