In an experiment, a bonnethead pup was born in a tank containing only three female sharks and no male shark.

This species is notable for its large, flat head, which gives it its common name. Taxonomic revision and further sampling are required to reevaluate the status of the bonnethead shark complex through its distribution range. Females are larger than males on average. Population genetic divergence of bonnethead sharks Sphyrna tiburo in the western North Atlantic: Implications for conservation Author: DazJaimes, Pndaro , Additionally, Escatel-Luna et al. These sharks are known to be very tough fighters. They move constantly following changes in water temperature and to maintain respiration.

Similarly, hammerheads can grow up to 20 feet, whereas most bonnetheads are small and grow up to 3 to 5 feet at most. Size at maturation, age at maturation, time of fertilization, rate of embryonic development, size at birth, the energetic investment in producing offspring, gestation period, and the incidence of fertility were found to differ between these population. Studies have shown that the population has declined by around 80%. The worlds three most fearsome species of shark, the tiger sharks, great white and bull sharks all showed up in lower numbers off Florida as they do every year.

Conservation of genetic resources of elasmobranchs is especially important as many shark species have exhibited significant population declines or range contraction as a consequence of increased fishing pressure, habitat loss, or other co-occurring factors (Shepherd and Myers 2005; Cortes et al. Browse 19 bonnethead shark stock photos and images available, or search for tiger shark or angel shark to find more great stock photos and pictures. Unlike the more familiar scalloped hammerhead sharks, bonnetheads have a much smoother and rounder hammer. Bonnethead sharks are considered harmless to humans.
