The most exotic species on the planet has a long nose like an airplane's supply hose

One of the unique fish species on the planet is the unicorn fish with a long, big nose like a human.

The spotted zebrafish (Naso brevirostris) has the entire head very much like the face of an angry man. The long nose was actually a long horn that protruded from the top of the head that looked like a refueling tube of an air force spy plane.

In addition, this fish also has a special ability to change color. Spotted mackerel has just been taken to Sealife Center at Weymouth in Dorset, England.

Another unicorn fish was even named "Nimrod" because it looked like a Royal Air Force military aircraft - RAF Nimrod was strange. It has a body of 7 inches (1, 7cm) long and a 2 inch (5cm) long horn.

Ad supervisor Matthew Fuller said: 'Nimrod looks pretty much like an airplane with its incredible appearance.

No one knows why they grow long horns right in front of their heads. It is not used as a weapon, or a swim aid, but I suspect that the horn is used for courtship and attraction. '

Even other unicorns don't look as special as Nimrod. Nimrod changes color and moves to darker areas when angry, stressed with other fish or when changing water.
