Morphology

bonnethead = bonnet + head (transparent) = bonnet + head

A straightforward descriptive compound: the shark is named for its bonnet-shaped head, so meaning follows directly from 'bonnet' + 'head'.

Etymology

The word bonnethead comes from the two English words bonnet ('small cap') and head because its wide, spade-shaped head looks like a little cap. So, the name fits this small, harmless hammerhead shark often found in bays and shallow water.
