The blacktip shark (Carcharhinus limbatus) is a species of requiem shark, belonging to the family Carcharhinidae. Though numerous, it is scattered around the world in tropical and subtropical waters. It commonly inhabits coastal areas and is also known to enter brackish and freshwater systems. This species reaches a maximum length of 3 m (9.8 ft).
The blacktip shark is characterized by a slim build, long snout, small eyes, crescent-shaped caudal fin, and first dorsal spine that is slightly longer than the second one. The pectoral fins are relatively long and narrow. The tips of its upper teeth are noticeably darker than its lower teeth, hence the name “blacktip.” Like other requiem sharks, it has a nictitating membrane that protects its eyes while hunting. The third tooth on each side of its lower jaw is larger than the rest and fits into a notch on the upper jaw.
Despite its name, the blacktip shark is not restricted to having blacktips; rather, this characteristic refers to the fact that in most individuals, the fins have dusky tips. Its coloring is generally pale blue above and white below, with a distinct pattern of small black spots on its flanks. However, individual variability in coloration exists: some sharks may be uniform in coloration (either all-dark or all-light), while others may display countershading (i.e., dark on top and light below).
What attracts blacktip sharks?
There are a few things that attract blacktip sharks to an area. One is the presence of other predators. Blacktip sharks are often found near areas where there are large predators, such as tiger sharks, because they know there will be an abundance of prey. Another thing that attracts blacktip sharks is the presence of food. They are often found near areas where there is a lot of activity, such as seagrass beds, because there will be more food for them to eat.
