The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
On average, an orca eats 227 kilograms (500 lb) each day. [70] While salmon are usually hunted by an individual whale or a small group, herring are often caught using carousel feeding: the orcas force the herring into a tight ball by releasing bursts of bubbles or flashing their white undersides. They then slap the ball with their tail flukes ...
Shark Anatomy (50693674756) The gill slits of a whale shark flaring as it expels water from its pharyngeal cavity. In the shark anatomy image, it depicts the beginning half of the shark, including the gills. The shark gills are especially important and were evolved from the chordate pharyngeal gill slits synapomorphy.
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 ]
English: Comparison of size of killer whale ( Orcinus orca) and great white shark ( Carcharodon carcharias ). This image assumes an average length of 4.6 metres for a great white shark (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), and 6.5 metres for a killer whale (males typically range ...
There has been one report of a shark attacking and killing a whale calf. This occurred in 2014 during the sardine run when a shiver of dusky sharks attacked a humpback whale calf. [98] Usually, the only shark that will attack a whale is the cookiecutter shark, which leaves a small, non-fatal bite mark. [99] [100]
Comparison of the size of an average orca and an average great white shark. Interspecific competition between the great white shark and the orca is probable in regions where dietary preferences of both species may overlap. [129] An incident was documented on 4 October 1997, in the Farallon Islands off California in the United States.
[41] [24] In comparison, large great white sharks are generally around 6 meters (20 ft) in length, with a few contentious reports suggesting larger sizes. [42] [43] [35] The whale shark is the largest living fish, with one large female reported with a precaudal length of 15 meters (49 ft) and an estimated total length of 18.8 meters (62 ft).
