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



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



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 Sharkshutterstock_332671025.jpg


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



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. Despite its painful sting, the bullet ant is not considered a major threat to humans, and will only sting if they feel threatened.

Vampire Bat



Vampire bats are the only mammal species that feed solely on blood. The common vampire bat, found in Costa Rica, feeds mainly on the blood of mammals like cows, horses, and pigs, and occasionally on the blood of birds. Luckily, they are not considered a threat to humans.
  • Habitat: Vampire bats are commonly found in Corcovado National Park, Puerto Viejo de Sarapiqui, Monteverde, San Jose and along the Cerro de la Muerte.
  • Season: Vampire bats are present in Costa Rica all year round!




Tarantulas are a fascinating part of Costa Rica's unique wildlife. Although they may appear intimidating to some people, tarantulas are mostly harmless to humans and play an important role in the ecosystem by controlling insect populations, and they are also preyed upon by larger animals like birds and mammals.
  • Habitat: They live in various regions of Costa Rica, including rainforests, cloud forests, and other forested areas. They can also occasionally be found in gardens and other urban areas. Don't panic, probably you wouldn't even notice!
  • Season: Tarantulas can be found in Costa Rica throughout the year, but they are more active during the rainy season
