Bull kelp is an annual seaweed-meaning it grows from a spore to maturity within a single year. It grows quickly, sometimes 10 inches (25 cm) in one day. Bull kelp reproduces by spores in spore patches (sori), which are heavy enough to fall to the ocean floor.
Bull Shark Range
Type: Fish Diet: Carnivore Average life span in the wild: 16 years Size: 7 to 11.5 ft (2.1 to 3.4 m) Weight: 200 to 500 lbs (90 to 230 kg) Group name: School or shoal Did you know?
Bull sharks are common in warm, shallow waters along coasts throughout the world. They are known for their particularly unpredictable behavior, as they often travel up rivers and can pose a large threat to those who venture in to the water there.
The Bull shark is found in tropical as well as in sub-tropical seas especially along the shores all around the world. The body shape of this omnivorous animal is undoubtedly remarkable. And that is because Carcharhinus leucas is much wider in comparison to its length than any other sharks.
The Bull Shark (Carcharhinus leucas Valenciennes) can be recognised by a combination of characters including a stout body, short blunt snout, triangular serrated teeth in the upper jaw and no fin markings as an adult.

Once the harem is established, the bull mates with any female not already pregnant or with young. After mating, the female gives birth 14 - 16 months later. The other females protect her while she is giving birth and then help the calf to the surface to take its first breath.
They live in groups or "harems," with an adult bull and 10-15 cows. During the summer-long breeding season, the animals collect by the thousands on isolated coastlines and islands. Females give birth to a single pup a year later.
