Boat-shaped.
Greek skaphos, boat.
Scaphocephaly (Greek kephalē, head) is a congenital malformation of the head which gives it an unusually long and narrow shape; something scaphoid is boat-shaped (—as a noun it is the name of a boat-shaped bone in the wrist); a scaphopod (Greek pous, pod‑, foot) is a type of burrowing marine mollusc, which has a tusk-shaped shell with both ends open.
