The wet areas of the Amazon are home to one of the largest non-venomous snakes, the green anaconda. It is the world’s heaviest and one of the longest snakes, growing up to 5.21 m. It is characterized by its olive green shade, with black spots along the length of its body and a distinguishing yellow stripe on one side.
These spooky critters have eyes on their heads in order to see what lurks outside of the water while staying almost entirely submerged, allowing them to wait sneakily for their next meal. They live in swamps, marshes, and slow-moving streams, mainly in tropical rainforests. They kill by constricting their prey and swallowing them whole. While you wouldn’t be their first choice of dinner, it’s recommended you steer clear.
Mediterranean Black Widow
Just by looking at it, you can tell that this spider is ten times more dangerous than the original Black Widow. This insect, with its crazy design and large venom glands, is much deadlier than the original Black Widow. You do not want to be by this tiny but very deadly insect, especially the female spiders, as their unusually large venom glands are extremely harmful, specifically to humans. You can distinguish the female from its male counterpart by its dark brown or glossy black color with a red or orange hourglass shape on their bellies.
And don’t let its name fool you into feeling sorry for it. Their names come from the practice of females eating males after mating. Males usually select their female partners by sensing chemicals in the web which tell them whether the female has eaten already.
