Though animal-related deaths are extremely rare, it’s good to have an idea of what animals can cause you some serious harm. The Brazilian Wandering spider is believed to be the world’s most poisonous spider. (Via Flickr)SpidersCosta Rica is home to some pretty scary-looking arachnids, but of the more than 20,000 species of spiders in the country, only a handful present any danger to humans. Unfortunately, within this handful is the most poisonous spider on the planet. The banana spider (Phoneutria fera), also known as the Brazilian wandering spider, is recognized as the world’s most toxic spider. Using a powerful neurotoxin, a bite from this spider causes a loss of muscle control, and if untreated can eventually kill through paralysis and asphyxiation. The spiders are common in the jungles and banana plantations in Costa Rica, but most bites occur from spiders hiding in boots or socks. The bullet ant is widely recognized as having one of the most painful stings of any creature on earth.

Common in Costa Rica and most of Central and South America, bullet ants are widely recognized as having one of the most painful stings of any insect on the planet. Bullet ant victims have described the burning, 24-hour-long pain as worse than being shot, giving the ant its common name. Crocodiles bask in the sun beneath a bridge over Costa Rica’s Tarcoles River. Experts say tourists and tour operators feeding the Tarcoles crocodiles and others throughout the country are part of what is making the country’s crocs more aggressive. Lindsay Fendt/The Tico TimesCrocodilesAfter the United States and Brazil, both many times larger than Costa Rica, this country has more deaths and attacks caused by the American crocodile (Crocodylus acutus) than any nation in the Western Hemisphere. Since 2013, five people have lost their lives to crocodiles in Costa Rica, and the problem shows no signs of stopping.In some areas, the expansion of tourist businesses and residencies has put crocodiles in a closer proximity to humans than ever before, while other parts of Costa Rica are now overpopulated with crocodiles fleeing their former territories. An improvisado, or improvised rodeo clown, is tossed by a bull during Costa Rica’s annual Zapote Festivals. At least 17 bull riders have died in Tico-style bullfights since 2003. Lindsay Fendt/The Tico TimesBullsIt’s no secret that bulls, when provoked, can be dangerous. Yet, for some inexplicable reason, each year thousands of Ticos choose to put themselves into a ring with a pissed-off 600-kilogram beast.Since 2003, toros at Costa Rican rodeos have killed 17 bull riders and dozens more improvisados, or amateur rodeo clowns. Red Cross officials estimate that during each of the major bull festivals in Costa Rica at least 20-30 people are treated for injuries. Cougars are among the most likely cats in the world to attack humans. (Via Flickr)Big catsDue to its size and powerful bite, jaguars (Panthera onca) are mistakingly thought by many to be the region’s most dangerous cat. Actually, of the cat species large enough to prey on humans, jaguars are the least likely to attack.On the other hand, cougars (Puma concolor), Costa Rica’s second-largest cat species, have been known to be aggressive towards humans in their territories. But while a puma is certainly powerful enough to wound or even kill a human, attacks are still very rare and there are no reports of deaths in recent years. Fer-de-lance bites account for almost all snake-related injuries in Costa Rica. Lindsay Fendt/The Tico TimesSnakesThere are 22 species of venomous snakes in Costa Rica, and the Clodomiro Picado Institute, a leader in snake-bite research, estimates that the country has at least two deadly snakes per hectare. Between the years 2000 and 2013, an average of 576 people were treated for snake bites per year, mostly in rural communities along the Pacific Coast.Costa Rica’s most dangerous snake by far is the fer-de-lance (Bothrops asper), known as a terciopelo in Spanish. While this snake is not Costa Rica’s most venomous, its aggression, breeding patterns, and rapid venom production mean it is accountable for nearly all serious snake bites in the country. Aedes aegypti mosquitos can transmit dengue and other diseases. (Courtesy of Frank Hadley Collins)MosquitosWe end with a small but mighty foe. A mosquito bite likely won’t kill you, but the disease you could get from that bite might. The year 2013 was a record year for dengue in Costa Rica, with more than 40,000 cases and at least 13 deaths.This year, a new, more dangerous disease has creeped into the country’s mosquitos with the chikungunya virus. The virus produces the same symptoms as dengue — high fever, headaches, muscle and joint pains, nausea and rashes — but is more aggressive and can last for as long as 10 months.Read previous Into the Wild columns here. “Into the Wild” is a monthly wildlife column from Tico Times staff writer Lindsay Fendt.
