Piranhas are freshwater fish that inhabits rivers, floodplains, lakes and reservoirs. Although often described as extremely predatory and mainly feeding on fish, their dietary habits vary extensively and they will also take plant material, leading to their classification as omnivorous. They are known for their sharp teeth and powerful jaws. In the dimension of Jumanji, Piranhas may congregate together while inhabiting rivers, lakes or swamps as deadly aquatic predators.

Behaviour

Piranhas have one of the strongest bites found in bony fishes. This extremely powerful and dangerous bite is generated by large jaw muscles (adductor mandibulae) that are attached closely to the tip of the jaw, conferring the Piranha with a mechanical advantage that favors force production over bite speed. Strong jaws combined with finely serrated teeth make them adept at tearing flesh. Splashing attracts Piranhas and for this reason, being in the water when already injured or otherwise incapacitated also increases the risk.
