It tends to reach an average length of 30 to 40 centimetres, and is filled with tons of venomous sacs, on each of its 13 spines. While the chances of being touched by the Stonefish are fairly small, those affected are encouraged to seek emergency medical help, as the venom can cause heart failure, severe pain and even death. Stonefish are also known to be one of the only species of fish that can survive up to 24 hours out of water.

Chances are that you may have heard about Piranhas, granting the numerous cartoons that the fish species appears in. At this moment in time, there are over 60 species of the carnivorous fish in the South American rivers and lakes. While the fish has often been regarded as a dangerous an indiscriminate killer, studies have shown that they mostly feast upon plant material. However, they do have strong jaws with sharp, triangular teeth that can cause serious wounds upon contact with human flesh. Piranhas are also dangerous due to their signalling mechanism. Once food is found, other fish in the region are signalled, which is why they often attack in groups.

The Tigerfish often proves to be fierce when caught, while also showcasing strong, predaceous instincts in their natural habitat. With this in mind, they are quick, salmon-shaped carnivores that feature strong teeth that tend to protrude once their mouths are closed, thus giving them their fierce look. Attacks on humans are rare, but even handling the fish can be dangerous considering their sharp spines situated on the gill covers.
