Hammerhead shark 雙髻鯊（Sphyrnidae )
The hammerhead 'hammer' is a complex structure that probably serves more than one purpose. :
(1) increasing electroreceptive acuity,
(2) increasing scent-tracking efficiency,
(3) increasing maneuverability,
( 4) increasing lift.

These sharks use a complex suite of 'body language' to establish social rank during daylight hours and use geomagnetic cues to navigate between seamounts at night, when the schools break up to hunt for prey.

I think it is Sixgill shark

係咪應該越細條感官越好??
