The word of the day is
fer-de-lance:
fer-de-lance, any of several extremely venomous
snakes of the
viper family (Viperidae) found in diverse habitats from cultivated lands to forests throughout tropical America and tropical Asia. (

"The rain forests of Mosquitia, which span more than thirty-two thousand square miles of Honduras and Nicaragua, are among the densest and most inhospitable in the world. 'It's mountainous', Chris Begley, an archaeologist and expert on Honduras, told me recently. 'There's white water. There are jumping vipers, coral snakes,
fer-de-lance, stinging plants, and biting insects. And then there are the illnesses - malaria, dengue fever, leishmaniasis, Chagas'."

Shouldn't that be "fers-de-lance"?
