    Years ago, on an excursion through the most captivating area of southern Venezuela, we stopped at Angel Falls, then toured the Carrao River in a Curiara, or long canoe down to Canaima lagoon. Here the water takes a rusty almost blood red color from abundant minerals and the beaches are powdery pink quartz. The area is well known for its “Tepuys” or flat top mountains. Walking an area off the beaten path with a guide, we came upon an area of large puddles with atypical movement. It seems that the area had flooded after recent heavy rains and the water overflowed it’s bank, sending many Piranhas into these puddles. Our guide took a large branch and put it into the puddle, thus showing the powerful jaws these ancient fish have. It was a site I’ll never forget.

      I wonder what would happen if urban cities get flooded as well and these fish roam freely with the help of rain water.

        it would depend on how well their prey has been swimming. if its been a good year for them then they wont even think to attack people.

    I have seen a specimen of piranha fish being displayed for sale in the seafood market in Dhaka Bangladesh.. At first I can’t believe its piranha as its appearance reminds me of the pictures I saw many times from different magazines, books and even from National Geographic films..But as you mentioned it here, now i realize that its indeed Piranha fish…
