10 Deadly Creatures under the Sea

7 Sting Rays

Most of us have heard about this ruthless killer group of fish which is a relative to the shark family. Found in tropical and sub-tropical conditions, Sting Rays like to spend most of their time under sand in the sea. The barbed tail of this fish is its primary weapon to defend or attack. They are usually calm but can attack humans if they felt threatened or someone just put their step on it. Death is guaranteed if left untreated.
