Captivating Creatures: The Crazy Wildlife of Costa Rica
Costa Rica is a biodiversity hotspot, home to many fascinating and unusual animals. While we do have some potentially dangerous wildlife, the overall risk to humans is low if you take proper precautions and follow basic safety guidelines!
Now let’s review some of the crazy wildlife found in Costa Rica:
The Poison Dart Frog

Highlights
These brightly colored frogs, including the Blue Jeans dart frog above, are some of the most beautiful and poisonous animals in Costa Rica. They come in a variety of colors and patterns, and their bright colors serve as a warning to predators that they are toxic. Local tribes used to rub their darts on the frogs back when hunting for small mammals. The toxins would paralyze their pray, stopping their heart, making it safe to eat the meat afterwards!
- Habitat: Tortuguero, Corcovado National Park, and Monteverde Cloud Forest Reserve. They are often found near streams, rivers, and other bodies of water.
- Season: Poison dart frogs are present in Costa Rica year round due to the country's tropical climate, but the wet season is the best time to spot them as they are more active and easier to see due to increased humidity and rainfall.
Green Palm Pit Vipers

Highlights
Green palm pit vipers are small venomous snakes found in Costa Rica. They're colorful and arboreal, and feed on small prey. Although their venom can be dangerous, they generally won't attack humans unless threatened. They're an interesting species with the ability to blend in with their surroundings, and play an important role in the ecosystem. If you see one, it's best to keep a safe distance and let them be.
- Habitat: In Costa Rica's rainforests, cloud forests, and other forested areas, including popular national parks like Tortuguero, Braulio Carrillo, Monteverde, and Manuel Antonio.
- Season: Green palm pit vipers can be found in Costa Rica throughout the year as they are native to the country. However, they are more commonly seen during the wet season.
The Hammerhead Shark
Highlights
Hammerhead sharks are named for their unique head shape, which allows for better visibility and hunting abilities. They are known to be aggressive hunters and can grow up to 20 feet in length. Despite their reputation, they are not typically a threat to humans and generally only attack if provoked or mistaken for prey.
- Habitat: Cocos Island, the Bat Islands, and the Gulf of Papagayo. These sharks are often found in deeper waters, so it is recommended to go on a guided diving excursion for the best chance of spotting them.
- Season: They can be seen in Costa Rica year-round, but the best time to spot them in Cocos Island is from May to November.
The Bullet Ant

Highlights
Gets its name from the intense pain of its sting, which has been described as feeling like being shot by a bullet. The pain can last for up to 24 hours, and is often accompanied by other symptoms such as fever, sweating, and muscle spasms.
