how many teeth does a zebra shark have
Zebra shark The zebra shark has a cylindrical body with a large, slightly flattened head and a short, blunt snout. The eyes are small and placed on the sides of the head; the spiracles are located behind them and are as large or larger. The last 3 of the 5 short gill slits are situated over the pectoral fin bases, and the fourth and fifth slits are much closer together than the others. Each nostril has a short barbel and a groove running from it to the mouth.[8] The mouth is nearly straight, with three lobes on the lower lip and furrows at the corners. There are 28–33 tooth rows in the upper jaw and 22–32 tooth rows in the lower jaw; each tooth has a large central cusp flanked by two smaller ones.[3]
Great white shark According to J. E. Randall, the largest white shark reliably measured was a 5.94 m (19.5 ft) individual reported from Ledge Point, Western Australia in 1987.[34] Another great white specimen of similar size has been verified by the Canadian Shark Research Center: A female caught by David McKendrick of Alberton, Prince Edward Island, in August 1988 in the Gulf of St. Lawrence off Prince Edward Island. This female great white was 6.1 m (20 ft) long.[5] However, there was a report considered reliable by some experts in the past, of a larger great white shark specimen from Cuba in 1945.[35][36][37][38] This specimen was 6.4 m (21 ft) long and had a body mass estimated at 3,324 kg (7,328 lb).[35][37] However, later studies also revealed that this particular specimen was actually around 4.9 m (16 ft) in length, a specimen in the average maximum size range.[5]
