Black tip shark

Social Life and Behavior
This shark species is very social and mostly found in larger groups with a strong hierarchy. Scientists believe a major reason for building groups is because these sharks tend to be very shy and timid towards other predators. Their philosophy is power in numbers.
Hunting Behavior
These are athletic and energetic hunters. They have a spectacular technique in which they catapult their body out of the water and rotate themselves the to four times before falling back into the water. It's unclear why exactly they do this, but it's often associated with hunting. They love to hunt for small fish like sardines and herrings, groupers, rays, and smaller sharks.
Offspring
Interestingly enough, females are able to reproduce asexually if males are not available. They are viviparous, meaning they give live birth to up to 10 pups per year. They reach maturity at an average age of about 4 years old for males and 7 years old for females. Most live to 13 years of age, sometimes longer.
Human Interaction
The Black tip Shark population has remained about even in recent years, even with commercial and game fishing. Their body parts are often used for fish fin soup and are harvested of shark oil, liver, and their flesh is considered a delicacy in many cultures. Since their reproductive rate is slower than most sharks, it's a species of concern.
The attack rate on humans is exceedingly low, but since they often swim in the same areas as people, conflicts have happened. There are no known fatal attacks on humans without provocation. It's important to note that these sharks are easily spooked. When threatened, they form an S-Shape with their bodies and roll from side to side.
