Not definitely black, no!! But to tell an anecdote, when I was a teenager I went with my best friend to the coastal area of ​​the north-central area of ​​Venezuela, specifically the state of Falcón, and on the main avenues at night you could see many small crabs marching with one of their pincers larger than the other were of that species and if you got close to them... they attacked you! It was very funny to see how something so small threatened you with so much force 😅

Very cool picture.
