THE SCARIEST!<br />
Not all relationships in an ecosystem are nice ones. Parasites are<br />
organisms that live in or on another living thing in order to survive,<br />
causing damage or even death. A parasitic, bloodsucking fish lives<br />
in the Amazon River – and it’s not a piranha. It is called a candiru,<br />
also known as the vampire or toothpick fish.<br />
The candiru finds its way behind the gills of other fish. Once<br />
there, it sticks out its spines so that the victim bleeds and provides<br />
it with a meal. Nasty!<br />
