Weight range of up to 1,500 kg Tiger sharks reach sexual maturity at the age of 4-6 years. The males are then 2.3 to 2.9 m and the females 2.5 to 3.5 m long. The mating season in the North Atlantic generally takes place between March and May. The gestation period ranges from 14-16 months, at which time a female can give birth to anywhere from 10 to 80 pups at a length of 51-76 cm. This is an astonishingly high number, where some scientists believe that this is attributed to the fact that the female feeds the embryos with a secretion passed by way of the uterus, in addition to the yolk sack. It is estimated that the sharks may live up to 50 years. The maximum size of tiger sharks can only be estimated. In 1964, Walter Maxwell caught an 807.4 kg IGFA all-tackle record tiger shark off South Carolina. A shark taken by professional fishermen off Newcastle (New South Wales, South East Australia) was 5.5 m long and was confirmed at 1,524 kg. The Iranian marine biologists H. Assadi and R. Dehghani list the maximum size of sharks in the Persian Gulf and the Gulf of Oman at 7.5 m, but do not list sources in this regard. A female shark that was caught in Indochina in 1957 is also mentioned in scientific literature. The French scientist P. Fourmanoir "calculated" a length of 7.4 m and weight of 3,110 kg based on a photograph taken in 1961. Reports of even larger sharks at up to 9.1 m in length could not be confirmed. One thing is true, even for the monsters amongst tiger sharks: They will disappear, never to be seen again, as soon as a standardized unit of measurement and calibrated scales come anywhere within their vicinity. Wolves of the Sea Tiger sharks migrate seasonally. During the summer, they move to cooler latitudes, returning to the tropical zones at the break of winter. The fish migrate across long distances within a short time and do not shy away from ocean crossings. Studies involving eight sharks which had been fitted with transmitters off the island of Oahu/Hawaii between 1993 and 1997 show that tiger sharks routinely cover larger territories, just like wolves. 61
