hammerhead 锤头鲨

因这种鲨鱼的头形如锤子而得名。

hammerhead (adj.): also hammer-head, 1560s, "head of a hammer," from hammer (n.) + head (n.). From 1796 (American English) in reference to a kind of shark, so called for its broad, transverse head. The animal is referred to as hammer-headed shark from 1752 and hammer-fish from 1745. The older name for it was balance-fish; there was a full specimen and a head of another under that name in the Royal Society Museum by 1681:
He hath his Name not unaptly from the ſhape of his Head, very different from that of all other Fiſhes, being ſpread out horizontally, like the Beam of a Balance; his eyes ſtanding at the two extremes, as the iron Hooks do at the end of the Beam. He grows sometimes to the length of four or five yards: but this is a young one.
