How is the shark in jaws characterized?

jaws) is the titular main antagonist of the 1974 novel jaws by peter benchley and the 1975 summer blockbuster film of the same name. he is a 25 foot, 6,000 pound great white shark that fed on amity island swimmers throughout the entire jaws (1975) movie.

answer:

jaws of sharks, like those of rays and skates, are not attached to the cranium. the jaw's surface (in comparison to the shark's vertebrae and gill arches) needs extra support due to its heavy exposure to physical stress and its need for strength. it has a layer of tiny hexagonal plates called "tesserae", which are crystal blocks of calcium salts arranged as a mosaic.this gives these areas much of the same strength found in the bony tissue found in other animals. generally sharks have only one layer of tesserae, but the jaws of large specimens, such as the bull shark, tiger shark, and the great white shark, have two to three layers or more, depending on body size. the jaws of a large great white shark may have up to five layers. in the rostrum (snout), the cartilage can be spongy and flexible to absorb the power of impacts.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
