Box Jellyfish are known to have a strong sting. Some can be life threatening. They have a bell with tentacles coming from the four corners. Some have multiple tentacles coming from each corner. Enoshima
Knowing that they can pack a good sting I was a little nervous getting in the water to get this picture. I did have a wet suit but there were holes in my armor. I was a bit concerned about the area of my neck and wrists. I did not get stung. They were mainly concentrated in a few areas of the surface. I did have to get in and out in the concentrated area.
