Guyana's wetlands and waterways harbor some of the most impressive wildlife in the Americas. The Rupununi savannahs and their network of rivers create a paradise for semi-aquatic species, offering some of the best wildlife viewing opportunities on the continent.

This guide focuses on three iconic species groups — caimans, capybaras, and giant otters — covering where to find them, when to go, and what to expect on your wildlife adventure.

Black Caiman: South America's Apex Predator

The Black Caiman (Melanosuchus niger) is the largest predator in South America, capable of reaching 5-6 meters (16-20 feet) in length. Once hunted nearly to extinction for their valuable hides, these massive reptiles have made a remarkable recovery in Guyana's protected waters.

Black Caiman Facts

Size: Up to 6 meters (20 feet)
Weight: Up to 400+ kg (880+ lbs)
Diet: Fish, capybara, deer, even cattle
Status: Conservation success story in Guyana

Night spotlight tours are the best way to see black caimans. Their eyes glow ruby red in torchlight, and on a good night in the Rupununi, you might count 50 or more caimans of various sizes along a single stretch of river.

Night Caiman Safari

The experience is thrilling — gliding through dark waters with a spotlight sweeping the banks, pairs of red eyes appearing everywhere. Guides can often approach within meters for photographs. These tours typically run 2-3 hours starting after sunset.

Capybara: The World's Largest Rodent

The Capybara (Hydrochoerus hydrochaeris) is one of Guyana's most endearing animals. These giant rodents — reaching up to 66 kg (145 lbs) — are highly social, living in groups of 10-20 individuals near water sources throughout the Rupununi.

Capybaras are semi-aquatic, excellent swimmers who take to the water to escape predators (including jaguars and caimans). They're often seen grazing on riverbanks at dawn and dusk, resting in the water during hot afternoons, or simply socializing in muddy wallows.

Capybara Facts

Size: Up to 66 kg (145 lbs)
Group size: 10-20 individuals typical
Diet: Grasses, aquatic plants
Behavior: Social, semi-aquatic, vocal

Pro Tip

Capybaras are most active at dawn and dusk. Listen for their distinctive calls — a mix of barks, whistles, and clicks used for communication. They're generally calm around humans, making for excellent photography opportunities.

Where to See Capybaras

Capybaras are abundant throughout the Rupununi savannah. You'll likely see them on almost any wildlife tour in the region. Key locations include:

Giant Otter: The River Wolf

The Giant Otter (Pteronura brasiliensis) is one of the world's most endangered mammals and one of Guyana's greatest wildlife treasures. Growing up to 1.8 meters (6 feet) long, these charismatic predators live in family groups and are wonderfully vocal and active.

Guyana is one of the last strongholds for this species, with an estimated 5,000+ individuals — possibly the largest remaining population on Earth. Seeing a family of giant otters fishing, playing, and communicating is one of wildlife tourism's greatest experiences.

Giant Otter Facts

Size: Up to 1.8 meters (6 feet)
Weight: Up to 32 kg (70 lbs)
Family groups: 3-8 individuals
Status: Endangered globally, thriving in Guyana

Incredibly Vocal

Giant otters have over 22 distinct vocalizations for communication. You'll often hear them before you see them — loud screams, snorts, and growls echo across the water as they coordinate hunting and warn of intruders. Each otter has unique throat markings, like a fingerprint.
