Dead Blue Cannonball Jellyfish – Not as pigmented as usual

The blue cannonball jellyfish has been present in particularly large numbers in the waters around San Felipe this summer. This round jellyfish is not particularly dangerous and while it can sting humans, it usually does not, though it is always best to avoid contact with jellyfish. The cannonball jellyfish is actually edible and is fished in some areas of the world. Apart from the blue variety seen around San Felipe, cannonball jellyfish can range from yellow to whitish-brown.

 

Blue Button Jellyfish washed up.

A few of these vibrant small jellyfish have washed up on San Felipe’s beaches lately. Measuring only an inch wide on average, these are not true jellyfish, but are known technically as Chondrophores, and are made up of colonies of polyps. They are often found in large groups. Blue button jellyfish have a very mild sting that may irritate the skin.

Also, if you have taken a walk when the tide is at its lowest, you may notice what looks like clear pouches of jelly along the beach. These jelly pouches are actually called mesoglea, and are the remains of jellyfish that have died. The mesoglea is simply the last part of the jellyfish to break down. It is mostly made up of water, and it was once the “jelly” looking part of the jellyfish. While it may feel uncomfortable if you accidentally step on one, it will not sting you.
