KNOCKING HAMMERHEADS
Scalloped hammerheads form some of
the biggest schools, or “shivers,” of sharks
anywhere in the ocean, often with hundreds
of fish gathered together in one place. These
schools swim close to shore during the day,
but move into deeper water to hunt at night.
The biggest ones are made up of younger
males or females. Individuals sometimes
knock one another with their snouts—perhaps
as signals of aggression or courtship.
