the only shark that looks like a wrench and sees behind its own head
means A shark of the family Sphyrnidae whose head is flattened and stretched sideways into a T- or hammer-shaped lobe, with an eye at each far end — or, by extension, a stubborn or blockheaded person.
from A plain English compound of 'hammer' and 'head,' both Old English words (hamor and heafod) of solid Germanic stock. The name describes exactly what the eye sees: a head shaped like the business end of a hammer. The word has been pressed into many services — for the shark, for hammer-headed tools and cranes, and as old slang for a dull or pig-headed fellow — all leaning on the same image of something flattened, blunt, and immovable.
