3 species and a system.


System:Circulatory system: pumping and channeling blood to and from the body and lungs with heart, blood and blood vessels.



 Catfish are probably the most finely tuned creatures on earth. Unlike most fish, they don’t have scales and their smooth skin gives them a heightened sense of touch. In addition tiny hairs that run along the catfish’s side are very sensitive to vibrations. So much so, catfish are rumoured to be able to detect earthquakes days in advance.

Blue Dragons float upside down on the surface of tropical waters and target blue bottle jellyfish. They ingest the poisonous cells of the jellyfish, which they then use on their own predators.
The Blue Dragon packs a deadly venom for anyone who dares touch its body.



 The critters are native to South American rivers, but they don’t spend all their time underwater. They have to come to the surface to breathe. They are not actually an eel but a species of fish called Kinfe fish.
All of an electric eel’s vital organs are crammed into the front 20 percent of its body. The rest is packed with 6000 cells that act like tiny batteries.
an eel can zap out more than 600 volts!
