Piranha Fish








Piranha Fish secrete a type of mucus, or slime, from their skin. This
slime provides protection against parasites and infections and helps
the Piranha Fish to move through the water faster. Some fish species
also release toxins in their slime which ward off enemy attacks. Other
fish species use their slime to feed their young.



Gills enable the Piranha Fish to breathe. Gills
consist of thin sheets of tissue containing blood vessels. As water
passes over the gills oxygen is absorbed into the blood stream Carbon
dioxide passes out into the water. The gills are protected by a large
bony plate called an operculum. Some fish species however have lungs
and breathe air.

of a fish. Fins are used for directing, stabilizing, or propelling the
different fish species in water. Numbers of fins vary between fish
species, but there are usually seven. Each of the fins on a fish are
designed to perform a specific function:




      Dorsal fins - The dorsal fin is located on the backs of fishes.

      Ventral fins. The ventral fin is located on the pelvic area of
fishes. The Piranha Fish has Ventral fins to lend stability in swimming.

      Caudal fins. The Caudal fin is located on the tail area of
fishes. The Piranha Fish has Caudal fins to propel through the water.

      Pectoral fins. The Pectoral fin is located on the breast area of
fishes. The Piranha Fish has Pectoral fins to for locomotion and side
