Flish

From Wikipedia, the free encyclopedia

The Flish is a fictional fish theorised and created for the television The Future is Wild. The flish is descended from cod, which was one of the last fish on Earth 200 million years from now. Unlike the cod, the flish can accomplish something beyond any modern fish: flight. Today, flying fish use their broad fins for gliding. The flish takes this one step further. It attaches powerful pectoral fin muscles to its gill arches. It breathes air outside of water. The flish retains two pelvic fins for resting atop the oceanic surface. To provide more force for flight, the caudal fins rotated 90 degrees, so they are flat like the flukes of a whale. Because birds are extinct when flish evolved, the flish filled every niche of seabirds along the global ocean that surrounds Pangaea II. They hunt silverswimmers and are in turn hunted by rainbow squid. Flish hunt by expanding toothed jaws from its beak-like sheath.

Along the northwestern coast of Pangaea II, flish evolved to fit the role of forest birds. Unlike the oceanic flish, the forest flish has hook-like claws on its pelvic fins for hanging upside-down. They are also much smaller, taking on the role of old world hummingbirds and general forest birds.
