That's 50 prayers to St. Patrick now and before every bedtime for the rest of your life in gratitude for keeping the snakes away.
Say hello to the spider-tailed Persian Horned Viper, another reason to never want to leave our creepy crawly-free island anytime soon. The viper, who has a weird fringed/pronged tail that resembles a spider, manages to combine two of the worst offenders in terms of nightmare causes and uses it as a means to lure in prey before devouring them whole. So a real nice chap all-in-all.
Only watch this is you're happy to never sleep easy ever again.
