English: Comparison of size of basking shark (Cetorhinus maximus) and human. The diagram assumes a length of 7 metres for the shark and 1.75 metres for the human (giving a ratio of 4ː1). The diagram assumes a length of 7 metres for the shark and 1.75 metres for the human (giving a ratio of 4ː1).
Great whites possess large, dagger-like teeth; basking shark teeth are much smaller 5–6 mm (0.20–0.24 in) and hooked; only the first three or four rows of the upper jaw and six or seven rows of the lower jaw function. In behaviour, the great white is an active predator of large animals, not a filter feeder.
This is the size that Gottfried et al. (1996) list as the 'largest mature female' in their study. The smaller silhouette is scaled to 4.7 metres (15 ft), the size Gottfried et al. list as the 'smallest mature female'. On average, male great whites are smaller than females. [2] The largest size obtainable by the great white is controversial.
North Atlantic sharks have 28–29 upper tooth rows and 26–27 lower tooth rows, while Southern Hemisphere sharks have 30–31 upper tooth rows and 27–29 lower tooth rows. [25] Each tooth has a strongly arched base and a nearly straight, awl-like central cusp, which is flanked by a pair of smaller cusplets in all but the smallest individuals.
The eyes are round and of medium size. The mouth usually contains 14 tooth rows (range 13–15) on either side of both jaws, plus one tooth at the symphysis (where the jaw halves meet). The upper teeth are stout and triangular in shape, while the lower teeth are narrower; both upper and lower teeth have serrated edges. [7]

[12] [13] The thresher shark has a short head and a cone-shaped nose. The mouth is generally small, and the teeth range in size from small to large. [14] By far the largest of the three species is the common thresher, Alopias vulpinus, which may reach a length of 6.1 metres (20 ft) and a mass of over 500 kilograms (1,100 lb).
