The same documentary showed footage of a whale shark timing its arrival to coincide with the mass spawning of fish shoals and feeding on the resultant clouds of eggs and ...
The silky shark (C. falciformis) is another contender for the largest requiem shark at a maximum weight of 350 kg (770 lb) and a maximum length of around 3.5 m (11 ft). The largest hammerhead shark is the great hammerhead ( Sphyrna mokarran ), which can reach 6.1 m (20 ft) and weigh at least 500 kg (1,100 lb). [ 31 ]

Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins ...
In the blue whale, the largest species, the fetus grows by some 100 kg (220 lb) per day just before delivery, and by 80 kg (180 lb) per day during suckling. Before weaning, the calf increases its body weight by 17 t (17 long tons; 19 short tons) and grows from 7 to 8 m (23 to 26 ft) at birth to 13 to 16 m (43 to 52 ft) long.
The great white shark is notable for its size, with the largest preserved female specimen measuring 5.83 m (19.1 ft) in length and around 2,000 kg (4,400 lb) in weight at maturity. [3] However, most are smaller; males measure 3.4 to 4.0 m (11 to 13 ft), and females measure 4.6 to 4.9 m (15 to 16 ft) on average.
Large males can reach a weight of over 10 t (9.8 long tons; 11 short tons). [33] [34] Calves at birth weigh about 180 kg (400 lb) and are about 2.4 m (7 ft 10 in) long. [35] [36] The skeleton of the orca is typical for an oceanic dolphin, but more robust. [32]
It is the largest freshwater fish in the world. The beluga also rivals the great white shark (Carcharodon carcharias) and the greenland shark (Somniosus microcephalus) for the title of largest actively predatory fish. [10] [11] The largest accepted record is of a female taken in 1827 in the Volga estuary at 1,571 kg (3,463 lb) and 7.2 m (23 ft ...
