Hopping around Costa Rica. Vickie Lillo treks through the Central American rainforests in search of unique amphibians. “Your sword smells funny, " exclaims Disney ’ s Captain Jack Sparrow, with dangling dreadlocks and mascaraed eyes, as he stares down the blade of his nemesis, Hector Barbossa. "Aye. Poison, ” the wily pirate from the Pirates of the Caribbean franchise replies. “From the innards of poisonous toads. Just a scratch, and you' re a dead man in minutes. " I ndeed, indigenous peoples - mostly the Emberás of Colombia and their related kinfolk who, over generations, migrated into Panamá via the Darien Province - utilise the toxic secretions of frogs from the genus Phyllobates, in family Dendrobatidae, to taint the darts of their blowguns. These are then used to hunt spider monkeys, birds and even the elusive jaguar, according to the Bulletin of the American Museum of Natural History in 1978, when the Golden Poison Frog (Phyllobates terribilis) became the third species of poison arrow frog confirmed to be used for this purpose; the others being the Kokoe Poison Dart Frog (P. aurotaenia) and the bright yellow, Black-legged Poison Frog (P. bicolor). Though most of the Amerindians prefer plant poison, specifically curare, Emberá and Noanamá Chocó tribesman rub the tips of their darts against the backs of living frogs or, much worse, impale them through the mouth and hind leg, since agitation results in an increased discharge of toxins. The natives must use extreme caution when collecting the frogs, which are sufficiently potent to kill 10-20 adult men. The amphibians are hauled around in wicker baskets until their poison is required. Luckily, none of Costa Rica’s native inhabitants - of Chibchense and Meso-American origin - exploit the poison dart frogs in this manner. In fact, all anurans are protected, whether they be semi-aquatic, moist- skinned frogs (rana in Spanish) or land-dwelling, dry -skinned, warty toads (sapos). It is illegal to kill them or even keep them as pets – the same goes for all of the nation’s endemic wildlife. But you can wit- ness their beauty and extreme diversity on a jungle night trek, like my husband Gustavo and I did in the town of La Fortuna, just two hours from the interna- tional airport in San José. Arenal Oasis Eco-lodge and Wildlife Refuge is an 18-acre private reserve owned by the Rojas Bonilla family, located smack-dab in the shadow of the smouldering volcano of the same name. An ecologi- cal farm, the back-to-nature facility boasts a dozen rustic cabins - eleven bungalows and a larger villa - all unobtrusively nestled amongst the amazing flora and fauna of the Costa Rican countryside. Two main activities are offered; morning birding tours and evening frog excursions. Freelance guide Jason Torres explains the reason for the incredible diversity of wild frogs - 28 species to be exact - that
