Gasteropelecid hatchetfish (tropical freshwater New World characoids...no
relation to the deep-sea sternoptychid hatchetfish) have the ability of
powered flight as opposed to the gliding marine exocoetid 'Flying' fish.
They have heavy pectoral muscles that move their long pectoral fins so fast
that they can leave the water and fly through the air in a straight line
while making a funny buzzing noise (Dammed annoying when you open your
aquarium lid and have a school of these guys start zipping out everywhere
in a panic).
Erm...back to dinosaurs now!!!
