Dangerous sea animals.

This  morning we started learning about oceans.
I found out that Lion Fish are the 10th most dangerous fish in the ocean. Lion Fish stings can be cured by putting the wound in some HOT water, and add balsamic salt. Sting Rays are the 9th most dangerous fish in the ocean. Sting Ray barbs can penitrate human skin and can potentially kill.
Later on, I want to find out all 25 most dangerous fish in the sea.
