Shark Stewards offers symbolic adoptions of the sharks it tags and releases in the waters of the San Francisco Bay.
Today I became the proud surrogate parent of a hammerhead.
Here are some fun facts about this odd fish:
- Hammerheads swim in large schools that sometimes exceed 100 sharks during the day, but at night are solitary hunters.
- The oddly shaped hammerhead (known as a cephalofoil) is used for navigation and to detect and trap prey such as stingrays
- Like humans, hammerheads have stereo vision, (each eye gets a slightly different view of an object), fantastic depth perception and better vision than other sharks.
- In 2001, a captive female bonnethead (a type of hammerhead) gave birth to a shark without having had previous contact with a male. While “virgin birth” or parthenogenesis had been seen in birds, snakes and reptiles, until 2001, it had never been documented in sharks.
