As it is too cold to try to find a swarm of anything where I live I had to try and find a picture that would work of this. As luck would have it I went to the mall to try to find a swarm of kids waiting for Santa and I got nothing :0( Guess its too cold. So I looked through some vacation pics from this past May and found this swarm of Violin Crabs. This was on Sanibel Island in Florida.
Ill try and revisit this word again.
