Hammerhead Shark Quiz – Cephalofoil Senses and Schools

Hammerhead sharks have a wide, flat head called a cephalofoil. It spreads their eyes apart for a wider view and is packed with tiny pores that sense the weak electric fields given off by prey.

Great hammerheads, the largest species, sweep the seabed for buried stingrays and pin them with their heads. Small bonnetheads were found in 2018 to digest seagrass as well as prey.

Scalloped hammerheads gather in large schools by day near seamounts at places like Galapagos and Cocos Island. Pups are born alive, but overfishing for fins has made several species endangered. Marine reserves and fishing limits now help protect their gathering places.
