Day 1 6/26/13 Love Makes a Family: Adopt a Shark

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.
