  2. They have a well-developed sensory and nervous system and have exception vision and heading capabilities, making them efficient predators.
  3. Bonnethead sharks can be found in shallow estuaries, shallow bays and over coral reefs. They spend night time hours on shallow grass flats, searching for active invertebrate prey. They move into deeper water during the day.
  4. Bonnethead sharks are the only shark where the two sexes look different from each other. The female Bonnethead sharks have a broadly rounded head, whereas males possess a distinct bulge along the top of their heads.
  5. The Bonnethead shark has one of the shortest known gestation period in sharks. Its gestation period lasts approximately four-and-a-half to five months. In contrast, the Dogfish has the longest known gestation period of any shark, at 18 to 24 months.
  6. A female Bonnethead shark gives birth to live young, with six to nine young per litter. A Bonnethead pup is about 35 to 34 cm long at birth.
