Throws fish carcass...Thousands of tiny animals gather it
Those tiny animal called water flea by locals fisherman
Their sense's so strong by flesh and fresh blood and carcass
a few minutes later...
The scientist tries so separate the fish carcass from the fleas with fire..
These fleas only lives on the shore, if they get into deep water or sand, they'll die
they eat like piranhas, came out from the sand and feed in a group
if you see the carcass just remains the bone of the fish.
