Flight
The most obvious trait of the freshwater hatchetfish is their enormously enlarged sternal region. This is accompanied by large pectoral fins and "extraordinarily powerful" associated muscles which "account for up to 1/4 the total body weight". "Quick beats of the pectoral fins" allow hatchetfish to "lift themselves half out of the water and glide along the surface ... Some species can even leave the water for short stretches" Because of this ability to fly and tendency to jump, aquariums used to house hatchetfish should have a cover which is tightly sealed to prevent these fish from escaping.

Famous quotes containing the word flight:
“Here I am.... You get the parts of me you like and also the parts that make you uncomfortable. You have to understand that other people’s comfort is no longer my job. I am no longer a flight attendant.”
—Patricia Ireland (b. 1935)
“It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy’s edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create “one world.” Instead of one world, we have “star wars,” and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet’s dead.”
—Gore Vidal (b. 1925)
“Sure smokers have made personal choices. And they pay for those choices every day, whether sitting through an airline flight dying for a smoke, or dying for a smoke in the oncology wing of a hospital. The tobacco companies have not paid nearly enough for the killing.”
—Anna Quindlen (b. 1952)
