Top 7 Most Dangerous Animals in the Caribbean

7. Amazonian Giant Centipede

Amazonian Giant Centipede
Scientific Name Scolopendra gigantea
Size Up to 30 cm (12 in) in length
Habitat Terrestrial, found in rainforests, caves, and savannahs
Location Trinidad and Northern Colombia
Danger Level Highly venomous and aggressive, considered dangerous to humans
Number of Deaths in a year  at least one human death (reported)

The Amazonian giant centipede, Scolopendra gigantea, is one of the world’s largest at up to 30 centimeters in length.

This incredible arthropod can be found in the leaf litter, fallen logs, and under stones of the South American and Central American jungles, as well as the Caribbean.

It is a carnivore that eats anything it can overpower and kill. It has the ability to overwhelm not just giant insects, spiders, millipedes, scorpions, and even tarantulas but also small vertebrates such as lizards, frogs, sparrow-sized birds, mice, and bats.

6. Southern Black Widow

Southern Black Widow
Scientific Name Latrodectus mactans
Size Females: about 1.5 inches (38 mm); males: smaller
Habitat Woodlands, fields, and other outdoor environments
Location Found in the Dominican Republic
Danger Level Highly venomous; potentially lethal to humans
Number of Deaths in a year  4-8 (on average)

Latrodectus mactans, also referred to as the shoe-button spider and the southern black widow, is a venomous species of spider in the genus Latrodectus.

The females are famous for their striking black and red appearance as well as the fact that occasionally they may consume their partners after mating. The venom can induce discomfort and other symptoms, although healthy persons seldom die from it.

Their Leg length in relation to the body is long. Females have an hourglass-shaped red marking on the ventral (under) side of their very rounded abdomens. They are shiny and black in appearance.

The size of females varies greatly, especially in egg-bearing (gravid) females. A female who is pregnant may have an abdomen that is larger than 1.25 cm (0.5 in) in diameter.

Moreover, the top of the abdomen of many female widows has an orange or red patch immediately above the spinnerets.

5. Fer De Lance Snake

Fer De Lance snake
Scientific Name Bothrops asper
Size Up to 2 meters (6.6 feet) long
Habitat Tropical forests, rainforests, and lowlands
Location Caribbean island of Martinique
Danger Level Considered one of the most dangerous snakes in the world
Number of Deaths in a year About 7 to 9 percent (people who do not receive anti-venom after they’re bitten)

It is one of the largest pit vipers, with a maximum length of 2.5 meters (8.2 feet) and a mass of up to 6 kilograms (13 lb). Its hue ranges from pale to dark brown, and its body frequently has yellow zigzag lines on each side.

Given the moniker “the ultimate pit-viper” due to its size, venomous output, and fangs, it is feared for being the snake that bites people the most across its area due to its defensive nature and proximity to homes.

Yet like other poisonous snakes, it stays as far away from people as it can.

4. Box Jellyfish

Box Jellyfish
Scientific Name Chironex fleckeri
Size Up to 30cm bell diameter
Habitat Coastal waters and estuaries
Location Caribbean Sea
Danger Level Extremely dangerous, potentially lethal.
Number of Deaths in a year 50-100

Cnidarian invertebrates known as box jellyfish (class Cubozoa) are identified by their box-like (or cube-shaped) bodies.

Several box jellyfish species generate powerful venom that is released upon contact with their tentacles. The bell of the box jellyfish medusa, from which it gets its name, is square and box-shaped.

A short stalk, or pedalium, with one or more long, thin, hollow tentacles hangs from each of the four lowest corners of this structure.

A velarium, or shelf formed by folding the bell’s rim inward, limits the aperture of the bell and produces a strong jet when it pulses.

Because of this, box jellyfish have been observed to swim up to 6 metres (20 feet) per minute, which is faster than other jellyfish.

3. Stone Fish

Stone Fish
Scientific Name Synanceia spp.
Size Up to 30 cm
Habitat Coral reefs, rocky areas, and sand/mud bottoms
Location Caribbean Sea, Cayman Islands, Trinidad, and Tobago
Danger Level Extremely dangerous, considered one of the most venomous fish in the world
Number of Deaths in a year more than 800 to 1,000 stings are reported every year, but the death rate is less.

Stonefish are sluggish bottom-dwelling fish that inhabit mudflats, estuaries, and areas with rocks or coral.

Thickset fish with enormous heads and mouths, small eyes, bumpy skin covered in lumps that resemble warts, and occasionally fleshy flaps, sit on the bottom motionless, integrating nearly perfectly in form and color with their surroundings.

These fish are dangerous. They are difficult to see, and when trodden on, they can inject a lot of venom through grooves in the spines of their dorsal fin. This fish can cause extremely severe and even lethal wounds.

They do not aggressively hunt these creatures, but they do consume some invertebrates that live on the bottom and other reef fish. They choose to wait for food to be brought to them.

Stonefish wait for hours before striking when their potential meal is only a body length away. They can readily suck down and swallow entire their unwary prey because of the pressure that their strong jaws and huge lips provide.

2. Shark

Scientific Name Carcharhinus leucas (Bull Shark), Galeocerdo cuvier (Tiger Shark), Carcharodon carcharias (Great White Shark)
Size 7-11.5 ft (2.1-3.5 m) for the bull shark, 10-14 ft (3-4.3 m) for the tiger shark, and Up to 20 ft (6.1 m) for the great white shark
Habitat Coastal and offshore waters
Location Caribbean Sea
Danger Level Highly dangerous
Number of Deaths in a year 333 human attacks, with 52 resulting in death.

Sharks found in the Caribbean Sea are Bull Sharks, Tiger Sharks, and Great White Sharks.

Sharks are an elasmobranch fish species distinguished by their cartilaginous skeleton, five to seven-gill slits on the sides of the skull, and unfused pectoral fins. The clade Selachimorpha (or Selachii), which includes modern sharks, is the sister group to the Batoidea (rays and kin).

According to some sources, the name “shark” refers to any extinct Chondrichthyes (cartilaginous fish) species with a shark-like shape, including hybodonts and xenacanths.

There are a number of species that are apex predators or organisms at the top of their food chain. The tiger shark, blue shark, great white shark, mako shark, thresher shark, and hammerhead shark are a few examples.

Shark teeth are continuously replaced throughout life and are implanted in the gums rather than being attached to the jaw.

Some sharks lose 30,000 or more teeth in their lifetime; replacement teeth grow in a groove on the inside of the jaw and advance continuously like a conveyor belt.

1. American Crocodile

American Crocodile
American Crocodile
Scientific Name Crocodylus acutus
Size Up to 16 ft (4.9 m)
Habitat Freshwater and brackish water habitats, sometimes coastal areas
Location Caribbean Sea, Hispaniola, Cuba, and Jamaica
Danger Level They are extremely dangerous to humans
Number of Deaths in a year More than 1,000 crocodile attacks a year result in death

The American crocodile’s habitat consists primarily of coastal locations. It can also be found in river systems, but it prefers salinity, therefore, it congregates in brackish lakes, mangrove swamps, lagoons, cays, and small islands.

Other crocodiles have saltwater tolerance due to salt glands beneath the mouth, but the American crocodile is the only species other than the saltwater crocodile that can live and thrive in saltwater.

They are found on beaches and small island formations that lack a freshwater source, such as numerous cays and islets in the Caribbean.

The nostrils, eyes, and ears are on the top of its head, allowing the remainder of its body to be hidden underwater for surprise strikes. Camouflage also aids in food predation.

In conclusion, a range of deadly animals endangers people’s lives in the Caribbean. So be careful and safe.
