      I found this information to be quite helpful to me as I often go to the beach with my dad and look through rock pools for shells.

      P.s. I will tread with caution next time I'm at the beach

      This was a very interesting article! The tiny critters in the ocean tend to be the most dangerous. The Irukandji jellyfish is also very small, but deadly.
