Favorite shark

I already posted about the Great White Shark, which is definitely my favorite and most intriguing shark. So I'll post about my second favorite, the Bull Shark! 
Scientific name: Carcharhinus leucas
Found in: Amazon River, Lake Nicaragua (can live in salt or fresh water
Reproduction: they mate in the late summer/early autumn. Pregnant for 12 months. Can have 4-10 pups. 
Predator/prey: Bull's eat mostly honey fish and sharks. Also includes turtles, birds, dolphins, etc. and humans catch and kill Bull Sharks. 
Adaptations: 1. adapted to live in freshwater 2. Has cartilage (no bones) 3. Have 2 dorsal fins.
Endangered/threatened?: they're near threatened. Why? Humans are catching them and not releasing them alive. 
3 facts: 1. Traveled as far up the Mississippi River as Illinios 2. Most responsible for near-shore shark attacks on humans, not great whites 3. Extremely territorial.
