Stargazer (photo: Wolcott Henry)
Using its pectoral fins as shovels, the stargazer fish digs into the seafloor sand, leaving its eyes and mouth exposed to spot and eat passing prey. The fish can also produce a defensive electric shock of up to 50 volts, which it creates via a specialized organ located behind its eyes. (via: National Geo)
Leaping Manta Ray (photo: Ralph Lee Hopkins)
The manta ray is a graceful swimmer, cruising the world’s temperate and tropical waters by flapping its large pectoral fins. When the mood strikes, however, those fins are used as wings to help launch the ray up to seven feet (two meters) in the air. Mantas have few predators—only large sharks—so it’s not known why they perform such aerial acrobatics. Because they sometimes leap in groups, scientists suspect the behavior may be a form of courtship—or simply a lot of fun. (via: National Geo)
For birds with wings nothing changes; they fly where they will and they know nothing about borders and their quarrels are very small. But we are always confined to earth, no matter how much we climb to the high places and flap our arms. Because we cannot fly, we are condemned to do things that do not agree with us. Because we have no wings we are pushed into struggles and abominations that we did not seek, and, then, after all that, the years go by, the mountains are levelled, the valleys rise, the rivers are blocked by sand and the cliffs fall into the sea.
