Hammerheads

Part of speech: noun

Definitions

1. A type of shark known for its distinctive flattened, lateral eyes and broad, hammer-shaped head that aids in navigation and hunting

3. Describing marine creatures characterized by their unique cranial structure, allowing for improved visual range and enhanced maneuverability in the water

Etymology: "Hammer" comes from Old English "hamor" and "head" from Old English "heafod," so the name is a plain compound of two everyday words. It describes the shark's broad, flattened head, which is shaped like a mallet with an eye at each end. The scientific genus name, Sphyrna, comes from the Greek "sphyra," meaning hammer. The shark's common English name and its formal name therefore describe the same shape in two languages. The same comparison has been applied to other creatures, such as the hammerhead bird, whose crested head looks like a mallet.

Synonyms: shark, predator, hunter
