From the smallest insects to the most unassuming creatures, discover the deadliest animals that are more dangerous than you ever imagined.

Cone Snail

With its beautifully patterned shell, the cone snail is deceptively dangerous. Its harpoon-like tooth can deliver venom that, in some cases, can be fatal to humans. Always remember: look, but don't touch!

Box Jellyfish

The nearly transparent box jellyfish can be hard to spot in the water, but its sting can cause heart failure. It's considered the most venomous marine creature on Earth.

African Elephant

They might be one of the most beloved animals in the world, but African elephants are also one of the most dangerous, causing more deaths in Africa than any other large animal.

Poison Dart Frog

The tiny, brightly colored poison dart frog is a lethal package. Indigenous tribes once used its venom for blowgun darts. Even touching this frog can lead to serious discomfort, and ingestion can be deadly.
