The common blacktip shark (pictured) is nearly identical in appearance to the Australian blacktip shark. Physically, the Australian blacktip shark can only reliably be distinguished from the common blacktip shark by the number of vertebrae (174–182 total, 84–91 before the tail in C. tilstoni, 182–203 total, 94–102 before the tail in C. limbatus).
The blacktip shark is an extremely fast, energetic predator that is usually found in groups of varying size. [5] Segregation by sex and age does not occur; adult males and nonpregnant females are found apart from pregnant females, and both are separated from juveniles. [ 3 ]
The blacktip reef shark has also been known to become aggressive in the presence of bait, and may pose a threat while attempting to steal the catches of spear fishers. [3] The blacktip reef shark is a normal catch of coastal fisheries, such as those operating off Thailand and India, but is not targeted or considered commercially important. [9]
In terms of length, blue whales have often been compared to three school buses lined up back to back. These whales measure 90-100 feet long and are estimated to weigh from 200,000-352,000 pounds ...

They vary widely in size, from as small as 69 cm (2.26 ft) adult length in the Australian sharpnose shark, up to 4 m (13 ft) adult length in the oceanic whitetip shark. [1] Scientists assume that the size and shape of their pectoral fins have the right dimensions to minimize transport cost. [ 2 ]
